Today in science we learned about gravity, tension, and compression. We found out that even though these forces are invisible, they are the ABC’s of structural engineering.

Today’s Challenge: Design and build a structure that demonstrates tension in some parts and compression in others.
Materials: 2 cardboard squares, 12 straws, 12 straight pins, 1/2m of masking tape, and 1/2m of string

The students did a fantastic job of working together. They are learning so much!

Joint construction and strengthening materials are next.
