This lab is a wonderful introduction to a capacity unit for 2nd grade. Students have fun using marshmallows to determine which container has the largest capacity.
This zip file includes:
-an introductory PowerPoint presentation
-a pdf file that explains the project (list of materials, directions, student journal page, data collection page, and reflection page)
My students had so much fun! Make sure to save a few marshmallows for the kids to eat at the end!
