Build a Bridge Together Challenge
Work as a team to build a bridge from household materials that can hold a book — a hands-on engineering challenge that demands real collaboration.
What You'll Need
- 1Paper and cardboard
- 2Tape and rubber bands
- 3Straws or popsicle sticks
- 4String
- 5Books for testing weight
- 6Two chairs or stacks for bridge supports
What You'll Need
Paper and cardboard for structural elements
Tape and rubber bands for fastening
Straws or popsicle sticks for supports
String for reinforcement
Books for weight testing
Two chairs or book stacks set 12 inches apart as bridge supports
How to Play
Set up the challenge: two supports about 12 inches apart. The bridge must span the gap.
Spread the building materials on the table.
Explain: "Build a bridge that connects both sides and holds a book for 10 seconds. You have 20 minutes."
Step back and let the team plan first. Encourage: "What's your design? Who's building what?"
During building, resist the urge to help. Let them discover what works and what doesn't.
When time's up, test with a book. Count to 10 together.
If it fails, discuss and rebuild. If it holds, celebrate and add more weight.
Why It Works
Bridge building is one of the best team challenges because it requires planning before building, role assignment during construction, and collective problem-solving when things fail. The physical nature of the challenge means ideas can be tested immediately — you find out in seconds if your design works. Unlike many team activities, bridge building rewards the team that communicates best, not the team with the strongest builder. The testing moment creates shared tension, and the success (or spectacular failure) creates shared memories.
Tips
Set a firm time limit. Pressure creates better teamwork and faster decision-making.
Don't pre-teach engineering principles. Let them discover through trial and error that triangles are strong.
If the bridge fails, ask: "What did we learn?" rather than "What went wrong?" Frame failure as data.
Take photos of each attempt. The progression from attempt one to a working bridge is a great visual story of iteration.
