Popsicle Bridges! For this activity, the set-up was simple. I separated the students desks by 1 foot, gave each group 25 Popsicle sticks and 3 feet of tape. Their goal was to make the strongest and most aesthetically pleasing bridge across the great desk divide!
This is sort of what I was talking about in my post on STEM in my classroom with the reproduction of the pyramids, aqueducts, etc. How these feats were acheived using engineering / technology of the past.
