1AKA: Scientific Inquiry The Scientific MethodAKA: Scientific Inquiry
2What is the scientific method? The scientific method is a series of steps to solve a problem or questionYou 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.
3Step 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.
4After you make observations, you become curious. Step 2: Ask a QuestionAfter 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?”
5Step 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.
6Step 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.
7Experiment 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.
8Step 5: Interpret the data Gather all your results/data from your experiment and create a visual graphic (chart, graph, etc.) to represent them.
9Step 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.
10Step 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.
