Simple Experiments and Investigations

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.

Example Activities

  • Mixing baking soda and vinegar to see bubbles.
  • Planting seeds to watch them grow.

Why Experiments Matter

Experiments help us learn by doing and let us discover new things.

Examples

  • Mixing colors to see what new color they make.

  • Testing which objects float or sink.

In a Nutshell

Experiments help us answer questions by testing and observing.
