## Ready when they can

- Carry out a simple test with one thing changing at a time
- Observe what happens and describe the result
- Use the result to suggest an answer to the original question

## Lesson: Testing to find answers

You have practised looking closely. A test can help answer a question about what you observe. Ask an adult to help choose a safe test. For a fair comparison, change one thing. Keep other things that could affect the result the same.

**Example.** Mia asks which kind of towel holds more drops before leaking. An adult helps her stretch dry, equal-sized pieces over matching cups. She uses the same dropper and waits the same time between drops. She counts only the drops held before the first leak. Towel A holds 2 drops and B holds 5. B held more in this test.

*(drawing: These bars show drops held before leaking. The longer bar shows more drops.)*

Watch while the test happens. Describe what you see. If you did not see clearly, say so. You may need to try again before suggesting an answer.

To read a bar chart, find the name under the bar. Read the number above that bar. Here, sponge C held 4 drops and sponge D held 6. The numbers count drops. A longer bar shows a larger count.

Use the result to answer the question you asked. Mia's result tells her about holding drops in this test, not towel colour. One test does not tell her what every towel will do. If someone says every ball bounces, one ball that does not bounce shows that the claim is not true.

**Recap.** Ask a question, make a fair comparison and watch closely. Use the result to suggest an answer.
