STEP 1: Identify variables ◦ Identify the following variables: ◦ Independent variable: what is being changed ◦ Dependent variable: what you will observe and measure
Step 2: write a hypothesis ◦ What do you think will be the relationship between your variables. ◦ When writing a hypothesis, use an if, then statement.
step 3: create a procedure ◦ Be specific! ◦ Make sure to include multiple trials. ◦ Be sure to have MEASURABLE results. ◦ Your procedure should be clear to someone who has not been in science class before.
Step 5: Analyze data ◦ With your data create a visual. ◦ What story does the graph tell? ◦ How does the independent variable affect the dependent variable? ◦ Is there a relationship?
Step 6: conclude ◦ Answer your original question. ◦ Accept or reject your hypothesis. ◦ Use actual data to provide evidence for what you say. ◦ Identify any sources of error. ◦ Write in the third person!
