A hypothesis is your guess about what will happen in an experiment. It’s like making a prediction. You use what you already know to come up with an idea.
To make a reasonable hypothesis:
- Ask a question about something you want to learn
- Think about what might happen
- Write it down in an “If…then…” statement
For example: “If I water a plant more, it will grow taller.”
Conducting Experiments
Experiments test your hypothesis. They help you find out if your guess was right or wrong.
Steps for a good experiment:
- Gather materials
- Set up your test
- Change only one thing at a time
- Experiment more than once
Remember to stay safe! Always ask an adult for help when using tools or chemicals.
