Build the Strongest Paper Bridge

What You’ll Need:

• 3–5 sheets of paper

• Tape

• Two stacks of books or cups (for supports)

• Coins or small objects (for testing weight)

Project Overview:
Design a paper bridge that can hold as much weight as possible using only simple materials.

Instructions:

1. Set up two supports (books or cups) about 6–8 inches apart.

2. Your goal is to build a bridge that spans across the gap.

3. Plan your design:

   • Think about how bridges stay strong

   • Try folding paper into shapes (like triangles or tubes)

4. Build your bridge:

   • Use tape to secure your design

   • Make sure it sits evenly across both supports

5. Test your bridge:

   • Slowly add coins or objects one at a time

   • Count how many it holds before collapsing

6. Record your result and think about what worked or didn’t.

Challenge Extension:

• Try a second design and compare results

• Which shape holds the most weight and why?
