Fair-Test Challenge
Maker Foundations · Low tech
Today’s challenge
Change one variable, collect evidence, and explain an improvement.
Grade 3 focusPicture routines, modeled tool use, two-option sketches, and short spoken evidence statements.
Grade 5 focusStudent-managed roles, measurable criteria, material budgets, and written design decisions.

Success example · inspiration, not a design to copy
Look closely. What makes this successful?
The same test is repeated and the team records evidence before changing the design.
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 two-trial test table and a before-and-after explanation supported by evidence.
My evidence
