Science Notebook: Plan a Fair Test
Name:
Date:
Today I am practising: changing one thing while keeping a simple comparison fair
1
Compare two paper towels. Circle the one thing you will change: brand.
2
List one thing to keep the same: amount of water.
3
Choose the same-size cup for both trials.
4
Predict which towel will absorb more.
5
Record one result after an adult-supervised test.
6
Explain why changing two things at once is confusing.
- Set up and supervise all water activities; use small amounts and wipe spills promptly.
- Keep the test to one clear variable and one simple measure.
- Distinguish a prediction from the result without treating the prediction as a score.
