Scientific Inquiry & The Scientific Method

Asking Questions About the World

Scientific inquiry is the process of exploring the world by asking questions, making observations, and seeking evidence-based answers. The scientific method is a step-by-step guide scientists use to investigate mysteries and solve problems.

Steps of the Scientific Method

  1. Ask a Question: Notice something interesting and wonder why or how it happens.
  2. Do Background Research: Gather information to understand your topic.
  3. Form a Hypothesis: Make an educated guess that you can test.
  4. Experiment: Plan and carry out a test to see what happens.
  5. Analyze Data: Look at the results and see what they mean.
  6. Draw Conclusions: Decide if your hypothesis was correct.
  7. Share Results: Tell others what you learned!

Why Is Scientific Inquiry Important?

Scientific inquiry helps us figure out how things work, from why leaves change color to how diseases spread. It’s not just for scientists—anyone can use it to solve problems!

Real-World Applications

  • Doctors use the scientific method to test new medicines.
  • Engineers use inquiry to design safer cars.

Examples

  • Testing which type of soil helps a plant grow best.

  • Figuring out why a bridge wobbles in the wind.
