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!

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!):

Here's a chapter from the NSTA publication Everyday Science Mysteries on Baking Bread.
