There are lots of fun shapes you can build using marshmallows and toothpicks.
Build two dimensional shapes that lay flat on the table or three dimensional shapes that stand up from the table.
(This note is for anyone just starting to learn about dimensions. Two dimensional means flat because it can only lay down. It only has length and width. A three dimensional shape is something you can wrap your hand around. It has length, width, and height.)
We built a triangle, 2 squares, a hexagon, and a lob-sided house. What can you build?
If you need some ideas of what to build or want to know more about building marshmallow structures we suggest you check out these two web pages. The first is from Abby the Librarian at the New Albany-Floyd County Library. The second is a YouTube video from Carmelo-The Science Fellow talking about how to illustrate engineering principles using marshmallows and toothpicks.
