## What Is an Experiment?
An experiment is a special test to find answers to questions. Scientists use experiments to learn how things work.
## How to Do an Experiment
1. **Ask a Question:** What do you want to find out?
2. **Make a Guess (Hypothesis):** What do you think will happen?
3. **Try It Out:** Do a simple test.
4. **Watch and Record:** Write down or draw what happens.
5. **Share Results:** Tell others what you learned!
## Safe and Fun Science
Always ask an adult for help and use safe materials.
