-
Choosing a Topic
- Figure out what area of science you want to learn about
-
Identify the Problem
- Write an Experimental Question
-
Research the Topic/Problem
- Find out what scientists know -or- what you already know
-
Write the Hypothesis/Prediction
- What you think will happen; "If... then... because..." sentence
-
Design the Experiment/Procedure
- Procedure: The steps you follow in the experiment
- Independent variable: Only one per experiment; factor we want to see what it does
- Dependent variable: Several per experiment; D= Data (Measurements & Observations)
- Experimental Group/Set-up: Where you test out the Independent variable
- Control Group/Set-up: Where you test out the opposite of the Independent variable
- Trials: The Exp. Group and the Control Group should each have at least 3 set-ups (ex: 3 plants in Exp. Group and 3 plants in Con. Group)
- Controlled Variable: Several per experiment; factors that are the same in the Exp. Group and Con. Group
-
Analyze the Data
- Figure out what the results are
-
Write a Conclusion
- Two paragraphs that answer the Experimental Question
- 1st Paragraph-- Claim: Answer the Exp. Question; Write about what you learned ; Write if the hypothesis was accurate or inaccurate
- 2nd Paragraph-- Evidence: Writes about data (measurements or observations) that you collected to help support your claim
