Paper Bridge STEM Challenge Worksheet

Science experiments lesson 26: Paper bridge challenge · Set 247 · 40 questions

What you do (Shape makes strength): 1. Place two books 15 cm apart, low and steady. 2. Lay a flat sheet across and add coins one by one in the middle until it falls. 3. Fold the same kind of sheet into a zigzag and test it the same way. 4. Record the coins each shape holds, then wash your hands.
