A test is a fun way to answer a question. If your question is "Which toy car is fastest?", you can find out by racing them!
A good test is a fair test.
This means you only change one thing at a time. If you are racing cars, you must:
- Start them at the same time.
- Let them go from the same place.
- Use the same ramp.
💡 Fun Facts
- You can test which material is best for an umbrella by pouring a bit of water on different things (like paper, plastic, and fabric) to see which one is waterproof.
- A simple test is to plant two cress seeds and put one in a sunny window and one in a dark cupboard. This tests if plants need light to grow.
- Scientists write down or draw what happens in their tests. This is called 'gathering and recording data'.
