Instructions for Day 4 activity (biology size game):

It was a huge success last year and the best activity we did! I hope you guys have fun doing it. It is
actually a good game for us too. I wasn’t able to get the correct order the first time.


  • Understand how small things actually are in comparison to other objects.
  • Understand the hierarchy of cell structure: atoms make up molecules which makes up organelles which makes up cells.
  • Prep work before activity:
  • Print out handout and cut the cards


  1. Go through the ppt to review cell structure and basic macromolecules
  2. Arrange the cards from smallest to largest size
  3. The answers are in the ppt
