TED Publishes My Video on TED-Ed!



I haven't had a chance to post about the video production process much, but here is basically how it went down:


  1. A friend nominated me on the TED-Ed website.  You can nominate your friends, too (or yourself!) by clicking the "Get Involved" link.
  2. Jordan Reeves, head of TED Ed, sent me an email to set up a time to talk on the phone about possibilities.  At this point, they make it pretty clear that the whole thing is completely exploratory--no guarantees.
  3. I agreed to try to write a script for a three minute video.  
  4. Discovered that writing a script for a good three minute video is really, really challenging.
  5. Sent the script to the editorial team.  Bit my nails for several weeks.
  6. The editorial team decided that they liked the script!  Hooray!  I made it to round three.  This one's easy--all I have to do is take a look at their suggested edits and check for scientific accuracy.  
  7. I have decided that all writers should have professional editors:  I am not a writer, but their editing added a certain je ne sais quoi to the wording in my script.  Definitely better than it was when I sent it.
  8. Round Four:  record the voiceover.  Since I live close to New York City, and I was on vacation at the time, I made the trip down to the TED Ed offices in Chelsea to use their cute little recording booth.  Rose, the science journalist and voiceover editor, directed me through the recording. I did not have to go down to the office--if you live far away, they send you a 'portable recording studio'.
  9. Then, I have to wait.  And bite nails more.  They send the voiceover and script out to a group of selected professional animators and wait until an animator chooses a voiceover.  If you don't get chosen, that's the end of that.  The reason the animators have the choice is because they often put in many MANY hours to put the videos together--and these are real professional who are volunteering their work hours (kind of like the teachers that put the lessons together).  Some of these guys/gals work for places like Pixar and Dreamworks.  Others just rock on their own.
  10. Marc Christoforidis picks my script!  WOW!  I am so excited.  Here is his professional reel on Vimeo.
  11. Then, we work together...emailing back and forth for weeks.  He sends me animated sketches (animatics) and stills to get my feedback and so I can check for accuracy.  He did an amazing job of interpreting some difficult places in the script.  I never even saw what he looked like until his picture was posted on the TED site!  He's got cool hair.

Edible Science Model Projects, Part 6: 2nd Annual Periodic Table of Cupcakes

Our Second Annual Periodic Table of Cupcakes was a success!





If you want to do this sort of project these are things to keep in mind:

  1. Give students plenty of time to plan the project, shop for materials (parents don't like last minute requests) and to make the items that need to be made ahead of time (cupcakes/fondant icing).  We have used a full period to plan it two weeks in advance.  This gives you plenty of time to send a notice home, and plenty of time for parents and kids to shop and make things.
  2. This year, it took a little longer to build the table.  I underestimated the difference in construction time that 4 fewer students would make--keep that in mind when you're doing this sort of project in your classroom.  I use our 90 minute block period for table construction (with the cupcakes and fondant icing already made).  Last year, with 11 students we finished it with time to take pictures and clean up.  This year, with 8, it took two hours, PLUS clean up time.  If you have a group of 20 students, with good planning you should be able to get it done in one class period.  
  3. Make sure you have one copy of the periodic table per student.  If you want the names of the "newest" elements, check online.  Unununium has a new name now, and so do a few of the others!  Mendelevium, Livermorium and Copernicium are a few.
  4. I suggest doing this project towards the end of a unit on the periodic table.  A great way to introduce the periodic table is by explaining why Dmitri Mendeleev's creation was so extraordinary...use this TED-Ed Video to start it off right!

This is AMAZING! My 7th grade students loved this TED talk...

I recommend showing this TED talk to all of your middle school students.  Amy Cuddy discusses how to change your life by changing the position of your body for 2 minutes!  My seventh graders absolutely loved this video:  they had a quiz in French class right after their science class, so we spent the final three minutes of our class in a POWER POSE to lower cortisol levels and elevate testosterone!

Photo from Amy Cuddy's TED Talk showing an example of the POWER POSE that we used in class.


I also liked this video because it tells the story of how personal experience shaped Dr. Cuddy's research and the problem that she investigated.  For those teachers who are focusing on teaching the scientific method, she clearly shows a slide that is her Problem Statement and discusses her hypothesis, as well as details on her experimental methods.  She also displays graphs of her experimental measurements (hormone levels).

I Feel the Need...the Need to Knead! Baking in Science Class for Thanksgiving

A beautiful tradition at my small, independent Montessori school is of breaking bread with the entire school community (toddlers, middle-schoolers, teachers and staff) on the day before Thanksgiving.

This year, in 7th year science class, we made a Hand-Kneaded Whole Wheat Bread, and had some science lessons along with it.  I do this with the 7th years because they already had life science with me last year, and they understand anaerobic cellular respiration, proteins in living cells and cell division already.   I got the recipe from Cooks Illustrated (a science lab of cooking!) and the science to go along with it from various sources.

Here are the loaves prior to baking (student-made!):

Edible Science Model Projects: Part 5--Cell Cakes Project, Year #2

Last year, we did a Cell Cake Project in the grand tradition of edible science model-making!  It was a tremendous success, and it remains the most popular post on my blog by far!
This year's newest member of the project;  The Bacterial Cell

This year is the second year of the project, and I decided to make it meatier (or cakier, or whatever) by adding a research and presentation component to it, as well as adding critical thinking to the project by adding different cell types and asking students to compare and contrast them.

"Remember, the primary goal of this project is to describe the similarities and differences between animal, plant and bacterial cells. "
-Mrs. Kaplan

Difficult Concepts: Teaching the Reason for the Seasons in Middle School

My last post on teaching the reason for the seasons in middle school focused on the biggest misconception of  most people when it comes to the concept, and an excellent curricular resource that I have successfully used for years to help teach this concept that is difficult to teach.  It is difficult to teach mainly because of the misconceptions that many people (including very smart people--some of them are teachers!).

I didn't even talk about the ACTUAL reasons--I spent all of my time on UNTEACHING a misconception, which is one of the challenges of being a science teacher!  Kids come to us with all sorts of ideas about how the world works, and we have to ensure experiences that help them understand what is right about their models and what ideas need, ahem, "reworking".  So here they are:

Here is a summary of the reasons for the seasons:
Images from http://www.physicalgeography.net/fundamentals/6h.html


1. The big, overarching, reason for the seasons is that the Earth is tilted 23.5 degrees from vertical on its rotational axis; and the Earth revolves around the Sun with the axis always pointing in the same "direction" in space. This results in several phenomena:

  • The number of daylight hours a region receives varies based on latitude and season.  If the Earth were not tilted, it would be like an equinox every day: 12 hours of sunlight and 12 hours of darkness.  In the northern hemisphere, in summer, Connecticut gets around 15 hours of daylight each day and 9 hours of darkness.  As you move north in latitude, the number of daylight hours in summer increases, so Anchorage, Alaska would get 19 hours of daylight on the same day that Jacksonville, Florida gets 14.


http://www.paulnoll.com/Oregon/Birds/climate-photoperiod.html
  • When there is daylight on a part of the Earth it warms up.  When there is darkness, it cools off.  In the summer, New England warms up for 15 hours or so and then cools off for 9 hours.  It warms for longer than it cools...this happens day after day after day so there is an overall warming effect.   In the winter, the opposite happens: there are many more hours of cooling time--15 hours of darkness--than warming time (9 hours) and day after day, this results in a cooling effect.
2. The other reason for the seasons is that the Earth is a sphere and so the solar intensity per unit of surface area differs based on latitude and time of year.  If daylight hours were the only thing that determined the average temperature at a certain latitude, then areas above the Arctic Circle would be the hottest places on Earth in Northern Summer, because it receives 24 hours of daylight (see chart above). So, there has to be some other factor at work here: many equatorial regions only have two seasons--hot and wet or hot and dry!  It's always hotter there than at the poles.  The solution is solar intensity per unit of area which changes based on the angular height of the sun.  
  • Angular height of the Sun in the sky changes throughout the day, with the Sun at it's highest point at solar noon; it also changes throughout the year, as shown in these diagrams:
Angular height of the Sun at 40 degrees Northern Latitude at different times of  the year.
http://www.extension.org/pages/62239/identify-sun-and-shade-areas-in-the-landscape
  • Solar intensity changes in proportion with angular height. A great activity to do with students is using a flashlight held at constant height over a piece of graph paper.  Trace the outline of the circle of light and then tilt the flashlight slightly.  The new shape is an oval with a much larger surface area (count and compare the squares) over which the same amount of light is spread.  So the solar intensity per unit of area in the image to the right is much less.

Now my post is too long, and I have to teach a class in 5 minutes!

Boy oh, boy! Cellular biology and immunology have come a long way since I was in college!

The last time I took a college course in cellular biology or immunology it was about 1994.  Since I am a science teacher, my professional journal-reading tends to concentrate on methodology research in science education, for example: Science Scope, Teachers College Record, or the Journal of Science Education and Technology.

Because of that, I live for "current events" projects or assignments in my classes.  It gives me and my students an opportunity to dive into what fascinates us about science at the cutting edge.  One of my tools for current events is my TED-talk-Tuesdays! I choose a few TED talks from TED.com and show them to my classes after previewing them (always preview your TED talks! you want to be prepared for jokes by the presenter or images--diagrams of human anatomy and such--that the kids may not be expecting).

My mind was blown today, though! The talk we watched today was by David Bolinsky, medical director of BioVisions biological animations studio at Harvard University.  It is amazing to me how much MORE we know now about the molecular mechanisms inside the cell than we did when I was in college!  I feel like I need to go back to school just to catch up!

After watching the talk, I searched around the internet for the full version of the amazing 3-dimensional animated, narrated and annotated video and found it here:

The Inner Life of a Cell - Harvard University

I found it helpful to also view the same process in an animation format that was less visually complicated.  For a traditional flash animation of the same process (shown in 2D) with labels and explanations, click this link: http://multimedia.mcb.harvard.edu/flash/extravasation.swf

I absolutely love my job! (aka Best Science Teacher Annual Goal...Ever!)

Like many professions, each year teachers create professional goals that they would like to accomplish for the year. Establishing these goals is meant to spur the development of a set of professional skills. Periodically throughout the year, teachers meet with supervisors to discuss progress on the goals and to collaboratively problem-solve any items that are hindering accomplishing of the goals.

Last year at my final 'goal progress' meeting, I met with other teachers to discuss our goals and talk about ideas for goals for the present school year.  I had the BEST idea for a goal...it was the kind of idea that makes you so excited to get started on accomplishing it!  What a way to love your job.

Here is what I wrote:
"Goal : To develop a thematic tradition in the middle school science classroom of “Celebrating Science” and to begin bringing that theme outward into the community. 
Steps I will take to achieve that goal:
  • To develop lessons, materials or events in science class that celebrate science.  For example: to create special thematic lab experiments and classroom decorations for Halloween; to organize events that celebrate the astronomical phenomena of the changing of the seasons, lunar or solar eclipses, milestones in science—like Newton’s birthday, or to further develop events like last year’s Periodic Table of the Cupcakes or the Cell Cake Project.
  • To build community awareness and anticipation of the events with the school newsletters, parent “awareness” email blasts and other media.
  • To guide middle school students to create ways of sharing the actual happening of the event with younger students in the school.  For example, by visiting the classes and sharing the Periodic Table Cupcakes with them after explaining what the project was all about and answering questions from the younger students."
This entire goal can translate from teacher-ese into English as:  "Spend your energy on how to have fun in science class!"

So this year, as I plan Halloween Science in the lab (Halloween falls on our extended-period lab day this year--Hooray!) I can have fun planning it...get really 'into it' and elaborate on it, develop it into something that excites even me!  All the while, I know I am working on accomplishing a professional goal that I set for myself which adds to my feeling of satisfaction about it.  

I will definitely post about my Halloween Science Day this year and other events...but not yet...some of my students and parents read this blog and I don't want to give anything away.  If you need some ideas, try this link to Science Bob's site of Halloween science demos.

By the way, a big shout-out to Liisa Petersen, who is one of the best science teachers I have EVER met, and an absolute pro at loving her job and having fun.  One thing that is on the list this year is to try to model her FLUGTAG event.

If At First You Don’t Succeed… GREAT!! — Maria Montessori

This article explains why a Montessori Education can be the key to an extraordinary beginning in the sciences, or any investigative field: 

If At First You Don’t Succeed… GREAT!! — Maria Montessori

This is one of the most important things about a good science program, too! My students were laughing the other day after watching an amusing TED talk by a researcher who said, "Do you know how I know that I made a measurement error? Beca
use that (dot on the graph/outlier) is messing up my data!" Guiding students to become friendly with error is essential in science because that is where many of the great discoveries have come from: what is assumed to be error or anomaly is actually a great discovery. Case in point: Kepler's ellipses.

TED Talk Tuesdays: The Science Of Happiness and Living Extraordinary Lives

Last year a friend gave me a book called Flourish by Martin E. P. Seligman, a professor of psychology at the University of Pennsylvania. I didn't read it.  Until this summer.  I highly recommend this book to educators, business people, members of the military or people who love someone.  Click here for an extremely biased review of the book.

As a scientist, the ideas in this book appeal to me because the findings about improving well-being and happiness and the techniques that Dr. Seligman presents and teaches in his book are research-based.  Life is short.  If I don't have to figure stuff out by trial-and-error, if I can just try something new that is proven to work--great!    I'm a working mother of two. It saves me time and improves my satisfaction with my life.  I definitely have had a few, "if I only knew this when I was younger.." moments while reading this book.

As a teacher of adolescents, this book and the UPenn Positive Psychology Center website gives me concrete, ready-to-use tools (like this complete 7-day curriculum on teaching positive psychology to adolescents) that I can use with  my students to help them learn to take an active role in improving their relationships with each other, their satisfaction with school and life and improving their outlook on life in a cognitively lasting way.

Today was TED Talk Tuesdays in my classroom.  We watch TED talks for science and technology current events and to observe effective presentation styles.  Here is the talk we watched today.  Shawn Achor is a psychology researcher and professor at Harvard University and CEO of GoodThink, Inc.  His positive psychology class at Harvard in 2006 was the most popular psychology class in Harvard's history. He also happens to be a very effective--and funny--presenter.  He presents many of the ideas that Seligman discusses in his book.  Watch out!  He only has 12 minutes and he talks really fast!  Enjoy!

Yale-Peabody Astronomy--Day 2, Part 1: Sunspots

My head is spinning!  We learned so much today...lectures on gravity, the Sun, meteorites and meteors! Okay, one topic at a time:  Sunspots.
This is the sunspotter tool that we used today.


Today, we got a chance to practice using a Sunspotter telescope.  An ingenious tool to safely view sunspots on the surface of the sun.  The Peabody Museum has purchased a supply of these tools and as part of the Fellowship, we can borrow them for about 1 month to do sunspot investigations with our students.  You can purchase one here.  Charting sunspot locations over a period of time can be used to show that the Sun rotates, and can be used to discover the direction of rotation of the Sun.  One interesting thing that I noticed, was that the Sun moved out of the field of view unbelievably quickly!  Every couple of minutes, the Earth would rotate enough so that the image of the Sun was completely off of the viewing platform.

I was quite surprised by this, and Dr. Michael Faison, astronomy professor and Director of the Leitner Observatory and Planetarium at Yale confirmed that the Sun's apparent motion is one solar diameter approximately every 2 minutes!  Fascinating!

Right here,  you can see today's image of the Sun from Spaceweather.com.  In the image, you can see many sunspots.  When we were using the Sunspotter, we could see 4 of the largest of them.

Update on Hydraulic Fracturing Post

I recently received a comment (that I did not post on my blog) about my recent post that was entitled "Teaching Earth Science and Hydraulic Fracturing". The comment read "Do you teach your students to look at both sides of an issue?" and provided a link to a rebuttal "movie" to the Gasland film. I didn't watch the rebuttal.

I never click on links that I'm not sure of, and I sure as heck don't post comments from anonymous people on my blog. If you have a comment worthwhile to post, you have an identity, or at the very least a profile that would allow contacting you for intelligent dialogue.  I love debates!

If you'd like to have a debate in your class on hydraulic fracturing, try this fantastic point/counterpoint article "Should Fracking Stop?:  Extracting gas from shale increases the availability of this 
resource, but the health and environmental risks may be too high.   It was published in the peer-reviewed journal "Nature".  It is a good guideline for concepts, ideas, good science and a bibliography of resources for older students.

I'll answer that question anyway. "Do I teach my students to look at both sides of an issue?". Yes, I do. Teaching students to absorb facts without encouraging and nurturing their critical thinking skills is useless and can be downright harmful--especially in the age of the Internet, the tabloid press and political ads in a Presidential election year!

I do not teach "anti-natural gas harvest" rhetoric. Educational studies have shown that when a teacher uses the kind of teaching techniques that would allow heavy inserting of his/her own ideals into discussion that it inhibits critical thinking (Kimbrough, 2007; Oliver and Lalik, 2004).  This is not good teaching.

Harvesting our country's natural resources and being ecologically responsible are not mutually exclusive

It is exactly that mindset that has politicized environmental care and stewardship from the start. There is nothing political about it. Humans will not survive if we carpet-bomb the atmosphere and poison our water sources.  So I encourage my students, their parents, my friends and family and my readers (that's you) to contact their congresspeople and tell them what they think of it all.

I am a scientist and a teacher.  I teach my students to look at all available (reliable) data and then to come up with solutions, ideas, causes and relationships and then to test again.  I also teach them that ANYTHING is possible.  Even hydraulic fracturing without chemicals that destroy aquifers and make residential and farmlands uninhabitable.

Teaching Earth Science and Hydraulic Fracturing (Fracking) Awareness

Today, I was writing curriculum for my Earth Science class.  I wanted to include some current news and issue to study about how humans are living with and/or affecting geologic events.  My focus was primarily on the earthquakes that can be associated with hydraulic fracturing techniques used to recover natural gas from shale deposits.  What the frack?  I was very disturbed by the reading and research that I did.  I guess I am wondering why it is totally necessary for the drilling companies to use hundreds of thousands of gallons of poison mixed with water for the drilling?

Most disturbing finding:  that in 2005, Congress passed legislation making hydraulic fracturing companies exempt from many key regulations in the Clean Air Act and the Clean Water Act?  I immediately made some calls to all of my congressmen about regulating the pollution created.

Regardless of my own personal convictions, as a science teacher, I believe it is my responsibility to present a current scientific controversy and teach students to think critically about it.  This means thinking about it from both sides and coming to a conclusion on your own.  This fantastic article called "Should Fracking Stop?" that was published in the peer reviewed journal Nature provides source-cited point and counterpoint.

"Extracting gas from shale increases 
the availability of this resource,
but the health and environmental risks may be too high."

Spectacular Sunset Effects in Manhattan on July 11 & 12, 2012

Sunset in New York City on July 11 & 12, 2012 will be spectacular!  The sunset on these days are aligned perfectly with the grid of streets and buildings in Manhattan giving photo-opportunities that are worthy of museum walls!

This is a photo that Neil deGrasse Tyson (the planetarium director at the Hayden Planetarium) took in 2001: 


Tyson has dubbed the effect: "Manhattanhenge", likening it to the solar observatory effects (lining up on the solstices) of the ancient stone circle Stonehenge on Salisbury Plain in England.  For more details, click here.
On the 12th of July you will see a half-sun: half above the horizon and half below at 8:25 PM.  On the 11th of July you can see the full disk of the sun at 8:24 PM.  However, you should definitely find your viewing spot a little earlier. so you can watch it come into view.

There is a special presentation on July 11 at the planetarium that will be followed by a live viewing of Manhattanhenge outside the museum.

Viewing suggestions from the AMNH website:
 "For best effect, position yourself as far east in Manhattan as possible. But ensure that when you look west across the avenues you can still see New Jersey. Clear cross streets include 14th, 23rd, 34th. 42nd, 57th, and several streets adjacent to them. The Empire State building and the Chrysler building render 34th street and 42nd streets especially striking vistas."

It's enough to donate TWO flocks of chicks to families with children-- This will change their lives for generations and change the lives of the people in their community! Read how it works: "In Tanzania, Omari and Kulwa were struggling to raise a family on just 50 cents a day. With the training and chicks they received from Heifer, egg sales have boosted their daily income to $2, so they can now buy food and still pay school fees. Now, through passing on the gift, all of the children in their village are going to school." Thank you so much for making this happen! I'll post an update when I get the donation confirmation

So, I checked my AdSense account.  I was going to remove the ads, because let's face it, I thought.  I'll probably never get a check from them.  THEN IT HIT ME:  Leave the ads.  In fact, let's put MORE of them in there.  Then, send a message to the universe that any AdSense check I get (I've never gotten one--I don't even really know how it works) will go straight to my favorite charity:  Heifer Project International.  

My goal is to be able to donate a Heifer, but maybe that is too modest a goal for such an amazing community.  I'll post on my AdSense account progress as you guys click like crazy on the ads...you just never know...

Broken Wine Glasses? Don't Fret; Model Gravitational Lensing, Instead!

Today, I purchased two very expensive crystal wine glasses to replace ones that I have broken.  On the way home, I broke them.  Accidentally.  Not to worry!  Now I can use the bases as very expensive crystal "gravitational lens" modeling tools.

In  this TED Ed video that I saw (amaaaaaaaaaaaaaaaaaaazing), physicist Patricia Burchat explains dark energy and dark matter in such a fascinating and interesting way.  I would love to have her as my physics professor.  In the video, she explains and demonstrates the use of a wine glass bases as a "gravitational lens" that bends space/time and light.
Watch it!  So good.

Meaningful Work

One of my favorite things each year at my amazing school is that I get to give a speech at our 8th year graduation.  It is a very moving ceremony each year, because many of our graduates have been in the school since they were very, very young--some as young as two years old!  Last year, the theme of my speech was Believe Impossible Things, but this year I took a different tone:


Meaningful Work
by Rebecca Kaplan

Good evening, everyone!  I am happy to see you all here tonight.  The theme of my speech this evening is one that is very dear to all Montessorians.  It is entitled, “Meaningful Work”.  I read a book this year called Outliers, by Malcolm Gladwell.  It was absolutely fascinating, I couldn’t put it down.  It is an amazing work of nonfiction that discusses the relationship between opportunity and meaningful work in the context of some of the most interesting people in our country.  Has anyone in here read this book?  Well, if you haven’t, I highly recommend it.  Malcolm talks at length about the meaningful work that we all are looking for and this is what he says about it:

“Those three things--autonomy, complexity, and a connection between effort and reward--are, most people agree, the three qualities that work has to have if it is to be satisfying.  Whether or not our work is fulfilling is what ultimately makes us happy.  Being a teacher is meaningful. Being a physician is meaningful.  Hard work is a prison sentence only if it does not have meaning.  Once it does, it becomes the kind of thing that makes you grab [your family} and dance a jig.” (p.149)

When you feel the way I do about the universe--the way it is put together and the way it is expanding and unfolding--you can see that it is easy for me to love being a science teacher and to find my work meaningful.  And if you look at this fantastic group of students sitting up here on the dais you can understand how much more rewarding and meaningful my work has been for me over the past two years.

I would like to extend my sincerest and most profound gratitude to each student and to their parents.  I have had the chance to be their science teacher, SSAT coach, lunch server, recess supervisor, student advisor and “professional expert project consultant” and I have enjoyed every minute.  The two years I have spent with these young men and women are two of the most extraordinary years in my career.

Never before have I been given the opportunity to spend as much time with my students as I have with you--getting to know you, laughing with you and learning how you learn best.  How rewarding it has been to be met with such willing dedication, passionate enthusiasm, tenacious hard work and above all, exuberant good humor.  We have done a lot of hard work, but we have also had a lot of fun.

Some of our work over the past two years includes:
  • Discovering Newton’s Laws, or “rolling lots of marbles down a track”.
  • Learning the foundations of experimental design, aka “making coke and mentos fountains”.
  • The principles of rocket science, affectionately referred to as “blowing stuff up”.
  • Exploring phase changes in matter, or “making ice cream in a bag”.
  • Discovering chemical and physical changes, which I like to refer to as “lighting things on fire”.
  • Learning the relationship between astronomy and cartography in navigation, or “getting lost in the athletic field (which is flat and has no trees) even though you had a compass and directions”.
  • Modeling the layers of the earth (playing with clay and playdough).
  • Using solar observations and models to prove the direction of the rotation of the earth, or “drawing with chalk all over the parking lot”.
  • Experimenting to examine a heating curve of H2O, affectionately nicknamed by the students as the “watching grass grow” lab.
  • Last and most: the extraordinary Expert Project.

The Expert Project was a complex independent study project that was hard work that came with an exciting and satisfying payoff at the end.  So, “Expert” and all of these other works that I have just told you about have in common the very qualities of meaningful work that Malcolm Gladwell was talking about in his book.   You can tell when you are doing meaningful work--it always has that same feeling: it’s hard work, but it’s easier somehow.  It is satisfying.  In fact, many times it also feels exhilarating.

Think back, everyone (graduates, parents, students and teachers): think back to some of your most fulfilling work at Fraser Woods Montessori.  It was independent and autonomous.  It was complex and difficult.  Above all, however, it was satisfying and rewarding.

My advice to our graduates is:
Remember that rewards of meaningful work are infinite--it pays you back with as much as you put in.  Reap the unlimited rewards that life has to offer you by finding your meaningful work and throwing yourself into it.

The philosopher Theodore Geisel commented wisely on the rewards of finding your own meaningful work.  Do you know who Theodore Geisel is?  Dr. Seuss!  He said:

“You have brains in your head.
You have feet in your shoes
You can steer yourself
any direction you choose.
You're on your own.  And you know what you know.
And YOU are the guy who'll decide where to go.

You'll look up and down streets.  Look 'em over with care.
About some you will say, ‘I don't choose to go there.’
With your head full of brains and your shoes full of feet,
you're too smart to go down any not-so-good street.

And you may not find any
you'll want to go down.
In that case, of course,
you'll head straight out of town.

It's opener there
in the wide open air.

Out there things can happen
and frequently do
to people as brainy
and footsy as you.

And when things start to happen,
don't worry.  Don't stew.
Just go right along.
You'll start happening too.

Congratulations!
Today is your day.
You're off to Great Places!
You're off and away!”

Exerpted from Oh The Places You’ll Go, by Dr. Seuss

I love you all, 8th years!  Good luck!

Win! Yale-Peabody Summer Astronomy Fellowship!

EPIC WIN!
I get to spend three days with the telescopes and planetarium at the Yale University Leitner Observatory.  "Excited" doesn't even come close to describing how I feel about this.  

It also comes with some perks: free money, plus a membership to the Yale-Peabody Museum (the original dinosaurs, people) multiple field trips with bus costs, planetarium shows and museum admission covered for all of my classes.  But that's, like, not even the best part.  

TELESCOPES.  Have you seen their telescopes?  Yes!  I am especially interested in learning how to build a scope/viewer that will let me and my students observe sunspots (and future eclipses).  I have no idea if they will teach me how to do it, but I'm going to ask.

TED-Ed Cricket Beat Box. TED Talk Tuesdays just got a boost.

I do this thing in my science class called "TED Talk Tuesdays" where we watch TED talks that I've previewed or that students have recommended.  Then, we talk about them.  It's way more fun than science current events from the newspaper.

The newest one I've seen is from the new-ish? TED-Ed series.  Science teachers, take note!

Science Vacations With Kids in Baltimore and DC

Okay!  So what does a science teacher do with her own children when on vacation?  I take them to fabulous science museums all over the country!  On the docket for this vacation:  a trip down to Baltimore and Washington DC.  Amtrak is having a deal on companion tickets to Baltimore: save 30%.  It's a pretty good deal and the kids love the train.

Why Baltimore? you ask.  The most amazing aquarium I've ever been to!  The Baltimore National Aquarium on the Inner Harbor in Baltimore.  When you get to the site, click Plan Your Visit>Discounts and Promotions to find deals on the tickets, which are pricey.

 I usually buy my tickets for everything a la carte, but you can find some packages for hotel, meals, and VIP admission to the aquarium right here at the Visit Baltimore Harbor Magic Site.  

Other destinations: the new science museum in Baltimore: The Maryland Science Center.  This museum is also right on the water in the Inner Harbor.  I booked my hotel on Priceline, and it allows you to select the Inner Harbor location.  

I haven't been inside YET, but I was in Baltimore in December and went for a walk around the beautiful harbor.  There was a long line outside the museum waiting for it to open on a sunny Sunday.  Both the Aquarium and the Science Center have incredible deals on Friday nights!  Starting at 5pm, they sell tickets for full admission for $8.  Amazing!  You can add on additional activities (like IMAX movies, 4-D theater, dolphin shows, etc.) for a small fee.

There are so many cool places to go with kids in Baltimore's Inner Harbor! But those are the two places I will take my kids in March.  

The next day, I have friends who live in DC, so we're staying with them and then going to the FREE museums there:  

The National Air and Space Museum is first on the list:  it's a classic!  I remember seeing my first IMAX film here in 1982...it was amazing!  The Space Shuttle Discovery is arriving there in April, so we'll be too early for that. 


Then, my older son is insisting on seeing the Hope Diamond at The Smithsonian National Museum of Natural History.  The best part is: we can go in and see the diamond and leave for lunch without worrying about admission:  the admission to the DC museums is free!

Science Project Timeline

I have been running science fairs successfully with my students for 12 years now.  For new teachers, managing a project of this size and scope can seem daunting.  Why not just copy what I've got so far and make changes where you'd like to make them?

This link will take you to my 6th and 7th grade Project Timeline, which has worksheets, guidelines and rubrics attached for most of the items that are to be submitted.  Let me know which work best for you...if you'd like me to post something in particular, drop me a comment!

Edible Science Model Project: Part 4: Periodic Table of the Cupcakes!

Here we are, folks!  The Periodic Table of Cupcakes was a phenomenal success--thank goodness for 90 minute lab block periods...

We had a TON of extra cupcakes.  So, after all of the classes in the school had an opportunity to see the Table of Cupcakes, we sent representatives to the Lower Elementary School classrooms to explain what they were and to share them.  The younger kids got a real kick out of "eating Plutonium" or "eating arsenic".


...too bad you can't taste them from there, the homemade marshmallow fondant was incredibly tasty.  Click here to view the inspiration for the project and the link for the recipe for the fondant.  Keep in mind--it's so easy a 7th grader can make it (a Very Smart 7th grader).

Modeling the Scale of the Solar System? Try THIS one on for Size--It Covers the Entire Country of Sweden!

Many teachers of astronomy begin with activities or projects that help students to grasp the enormous scale of the solar system--which is a good idea, because all of the diagrams we see in textbook give us the poorest sense of it.  (See this post for more information on that...)




However, here's the biggest one on our planet--in Sweden.  It begins with the Sun (the Ericsson Globe) in Stockholm--modeled at 110 m in diameter and ends at the Terminal Shock.  The Terminal Shock (the edge of the heliosphere) in the Swedish model is 950 km away from Stockholm!

Educational Rap: Rhythm, Rhyme, Results has excellent new science songs!

They have SMASHING new songs--The Planets and The Periodic Table of the Elements.  My students request the songs regularly.  By  most accounts, they preferred The Planets right away; some students now are finding that they like the Periodic Table better, but maybe just because that is what we are studying.

Click here to view the lyrics, listen to samples of the songs and/or purchase the music.  Today only, you can download a FREE song on the Civil Rights Movement.

Edible Science Model Projects: Part 3--The Periodic Table of Cupcakes!

Our success with the Cell Cakes in 6th year science inspired our 7th years to create the Periodic Table of the Cupcakes which will be occurring next week on Wednesday.  Maybe I'll ask Daria Musk to join us in a hangout of the creation!?   That would be really fun.  I will post photos and a student-edited video when we are done.

Instead of using icing for the writing, we are going to use edible cake pens (found here) and we are making our own Marshmallow Fondant.  Why the extra work?  The pre-made fondant that you can purchase tastes not-great, and by all accounts this easy recipe makes delectable fondant that you actually enjoy eating, instead of peeling it off the cake (like an orange rind) and then eating it.

Why fondant?  Because then we can pre-make the atomic symbol:  we can write out the symbol and the atomic number (and mass if we have the space) and then form an assembly line of sorts to put it all together. Theoretically.  We'll see.

Anyway, here's the YouTube video that inspired us and the Huffington Post article that describes the video.

Edible Science Model Projects: Part 2--Cell Cakes!





So this year, we made Cell Cakes instead of Jello Cells.
This is a project that you don't have to encourage the kids with--they want to spend all of their time discussing, planning and creating it.  They seem to have an inexhaustible supply of energy for learning about cell anatomy when they are going to be able to eat it!

The criteria for these cakes were:

  1. Must contain all of the structures that were on the worksheet that I handed to them: (nucleus, golgi body, ER, rough ER, ribosomes, vacuoles, mitochondria, cell membrane and cell wall for plants) 
  2. Must contain a minimum of three additional structures (this requires independent research)
  3. Labels are clear and legible
  4. Each structure is easily discernible from the others and looks as much like the real thing as is practicable.
The advantage of the Cell Cake over the Jello Cell:
  • less messy 
  • no heating required
  • the cakes can be baked at home and brought to school
  • more attractive and tastier product
Disadvantage:
  • looks (usually) exactly like the diagrams in the text and online, so students don't get a sense of how all cells look slightly different--the ziploc bag animal Jello Cells took care of that.
  • no opportunity for sectioning lessons, which was a MAJOR disadvantage
