Understanding the Scientific Method: A Step-by-Step Guide

The scientific method is a structured approach to inquiry that helps us systematically investigate questions. This guide outlines the five key steps: 1) Ask a Question – identify what you wish to explore, such as the effects of sunlight on ice or plant growth. 2) Form a Hypothesis – make an educated guess about the outcome. 3) Develop a Procedure – create a step-by-step plan for your experiment. 4) Gather Data – record your observations and results from multiple trials. 5) Draw a Conclusion – analyze the data to validate your hypothesis.

  2. Steps in the Scientific Method Step 1: Ask a Question Step 2: Form a Hypothesis Step 3: Develop a Procedure Step 4: Gather Data Step 5: Draw a Conclusion

  3. Ask a Question What do you want to learn about? • What happens to ice in the sun? • Does a plant grow faster in the sun or in the shade?

  4. Form a Hypothesis Make a prediction about what you think will happen. • The ice will melt faster in the sun. • The plant will grow better in the sun than in the shade

  5. Develop a Procedure Make a plan that says what steps you are going to take and what materials you will use: • Step 1: Make ice cubes • Step 2: Put one set of ice cubes in the sun and one in the shade. • Step 3: Measure the time it takes the ice to melt.

  6. Gather Data Make a note of what happens. Do more than one trial. • Write down the time it takes ice to melt. • Write down how many inches a plant grows.

  7. Trials Each “trial” means one test. When you retest, you will have more than one trial. Repeated tests make your results more reliable.

  8. Draw a Conclusion What does the evidence (your data) tell you about what is happening? Was your hypothesis right or wrong?
