Grab your materials and set the timer! For this STEAM-based activity, students will need to build a freestanding bridge as tall as possible from one square to another.
Setup: On the floor, use masking tape to create two 6in x 6in squares (Square 1 and Square 2) that are 8 inches apart.
Challenge: Build a freestanding bridge as tall as possible from Square 1 to Square 2 that can hold as many coins as possible. Freestanding means that your structure cannot be attached to anything. Your bridge must not touch the area between the two squares.
Materials: 2 pieces of paper, 2 cardboard tubes, 6 straws, 2 chenille stems, 6 paper clips, 4 mailing labels (or 6 inches of tape), coins
Time: 8 minutes
A. 10 points if your freestanding structure does not touch the space between Square 1 and Square 2
B. 20 points if the bases of your structure are completely in the 6-inch squares
C. 5 points for every inch of height of your structure
*height is measured vertically from the center of the space between Square 1 and Square 2
D. 10 points if your structure successfully holds 10 or more coins
E. 20 points for the creativity of your structure
F. 20 points for how well your group worked together
