1 AKA: Scientific Inquiry THE SCIENTIFIC METHOD

2  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. WHAT IS THE SCIENTIFIC METHOD?

3  An observation is when you use your senses to view the natural world.  Example: Students observed that some frogs in their area had deformities. STEP 1: MAKE AN OBSERVATION

4  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?” STEP 2: ASK A QUESTION

5  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. STEP 3: WRITE A HYPOTHESIS

6  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. STEP 4: PERFORM THE EXPERIMENT

7  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. EXPERIMENT CONTINUED.

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  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. STEP 6: MAKE A CONCLUSION

10  Share your ideas, experiment, results, and conclusion with peers so they can learn.  You can communicate by talking, writing, presenting, etc. STEP 7: COMMUNICATE YOUR RESULTS
