The Scientific Method The method that all scientists use to conduct experiments The goal is to solve a problem or to better understand an observed event
Step 1:Ask a Question The first step to any experiment is to ask a question Example: Why does it get warmer in a room when there are a lot of people in it?
Step 2: Form a Hypothesis A hypothesis is a proposed answer to a question You are predicting what will happen It can be tested Example: The temperature of the room will increase when more people are in the room.
Step 3: Test Your Hypothesis Set up a controlled experiment to test your hypothesis Manipulated Variable: The variable that causes a change in another Responding Variable: The variable that changes in response to the manipulated variable
Test Your Hypothesis Cont. “ We will test our hypothesis by putting different amounts of people in the same size room at a same starting temperature for 45 minutes and measure the temperature at the 45 minute mark.” Manipulated Variable: The amount of people Also known as the Independent Variable Responding Variable: The temperature Also known as the Dependent Variable
Step 4: Analyze Data Collect data from your experiment in an organized way Usually in tables or graphs Does the data support the hypothesis? If yes, continue to step 5 If no, repeat the experiment or conduct a different one
Step 5: Develop a Theory (Conclusion) A well tested explanation for a set of observations To be proven, a theory must always be true
