Paper Beam Lab
Low-Tech Structures · Hand tools + basic materials
Today’s challenge
Fold and compare beam shapes using the same span and load.
Grade 3 focusSmall models, simple measurement, teacher-provided tests, and one purposeful revision.
Grade 5 focusLoad ratios, repeated trials, tradeoff analysis, and material-efficiency scores.
Success example · inspiration, not a design to copy
Look closely. What makes this successful?
Folded shapes create stronger beams without using unlimited material.
What to do
- Understand. Read the challenge. Circle the important need, rule, or safety limit.
- Plan. Use the thinking spaces below before you begin making.
- Make. Build, model, code, practice, or investigate carefully with your team.
- Check. Use evidence—not guesses—to decide what worked.
- Improve or explain. Make one useful change or share your strongest conclusion.
Engineer’s thinking
1. What will you keep the same?
2. What one thing will you test or change?
3. Record the result with a number, tally, or clear observation.
4. What should you improve next?
Evidence check
Show what you learned.
Your teacher will look for: A beam comparison chart, measured load result, and claim about the strongest shape.
My evidence
