Let’s get started
A testable question is one we can explore by observing or measuring fairly.
Learn together
- Wonder: Which paper airplane flies farther?
- Change just one feature (for example, paper type) while keeping other things the same.
- Measure both flight distances and record the results.
Example to explore
Question → Fair test → Measurements → Evidence
Try it yourself
- Which is easiest to test with a measurement?
- During a fair test, you should usually…
- Write one question you could test safely with a grown-up.
Hands-on project
Design and test two safe paper airplanes, measure three tries each, and make a mini results chart.
Reflect and grow
What evidence helped you answer your question?
