1 AKA: Scientific Inquiry
The Scientific Method AKA: Scientific Inquiry

2 What is the scientific method?
The scientific method is a series of steps to solve a problem or question You might hear this referred to as scientific inquiry. You and other scientists use the scientific method every day to answer a question or solve a problem.

3 Step 1: Make an Observation
An observation is when you use your senses to view the natural world. Example: Students observed that some frogs in their area had deformities.

4 After you make observations, you become curious.
Step 2: Ask a Question After you make observations, you become curious. A question will be based off of your observations and curiosity. Example: “Could pollution be causing the frog deformities?”

5 Step 3: Write a Hypothesis
A hypothesis is a possible answer to your question. A hypothesis is written in what we call an “If/then” statement. Example: If there is an increase in exposure to pollution, then some frog eggs will develop into deformed frogs.

6 Step 4: Perform the Experiment
An experiment is when you use specific materials and follow procedures to test your hypothesis. This is where you make more observations and collect data! Example: Students created 3 groups of frog eggs and exposed each group to pollution for different amounts of time. The number of deformed frogs which developed was recorded for data.

7 Experiment continued. Control Group/Variable – A group that receives no experimental treatment/the variable that doesn’t change. Independent variable – the one factor that is changed during an experiment. Dependent variable – the variable that changes because of the independent variable.

8 Step 5: Interpret the data
Gather all your results/data from your experiment and create a visual graphic (chart, graph, etc.) to represent them.

9 Step 6: Make a Conclusion
A conclusion is a summary of your experiment and what you have learned from it. Example: The pollution experiment supports the hypothesis that frog deformities can be caused by exposing the eggs to pollution.

10 Step 7: Communicate your results
Share your ideas, experiment, results, and conclusion with peers so they can learn. You can communicate by talking, writing, presenting, etc.
