Scientific Inquiry

What Is Scientific Inquiry?

Scientific inquiry means asking questions about the world and trying to find answers through careful investigation. Scientists use special steps called the scientific method.

Steps of Scientific Inquiry

  1. Ask a Question: What do you want to know?
  2. Make a Guess (Hypothesis): What do you think will happen?
  3. Plan an Experiment: How can you find out?
  4. Test Your Idea: Do the experiment and watch what happens.
  5. Record Results: Write down or draw what you observe.
  6. Share What You Learned: Tell others about your findings!

Why Is This Important?

Scientific inquiry helps us solve problems, learn new things, and become great thinkers!

Try It!

Think of a question like, "What happens if I put a bean seed in the dark?" and investigate!

Examples

  • Testing if plants grow better in sunlight or shade.

  • Observing which objects sink or float in water.

In a Nutshell

Scientific inquiry is how we ask questions and find answers by experimenting and observing.

Key Terms

A guess you make before testing to see what will happen.
Experiment
A test you do to find out if your guess is correct.
