1 Introduction to the Scientific Method: Planning an Investigation Launch It!Introduction to the Scientific Method: Planning an Investigation
2 Launch it! Intro to the Scientific Method Key Question: What steps do scientists take before they actually do the experiment?Initial Thoughts: (Hint: what did Dr. Golderberger do?)
3 Evidence: Airplane Launcher BrainstormIn your lab group, “play” with your launcher and make observations. You have 10 minutes.Things I could change or vary:Things I could measure or observe:
4 Choosing Variables I will Change: I will Measure: I will keep these the same:What vocabulary words could you use for these?Manipulated/independent variable And Responding/Dependent variable
5 Asking A Question:What is the effect of _______________________ (manipulated variable)On the _____________________? (Responding Variable)
6 Making a Prediction or “Hypothesis”: As the _______________________ increases/decreases (Manipulated Variable) the _______________________ (Responding Variable) will increase/decrease/stay the same.You also need to provide a reason WHY you making that prediction. More on that later…
7 Evidence 2: Scientific Questions W.S. Change the broad, general question into a TESTABLE question.Work in your table groups. I will check 1 person’s worksheet in each group.
8 The Scientific Method Make observations Think of a testable question Research the topicMake a hypothesisPlan the experimentConduct the experimentRecord the dataAnalyze the dataMake a conclusion/Revisit hypothesis
9 10/2/12 Do Now: Analysis Questions What are the first 2 steps a scientist does in the scientific method?Why did you predict the responding variable the way you did?Why is it important to keep the control variables the same?
10 Summary 5-6 sentences Make sure this is thoughtful and thorough. What did you think before about the scientific methodWhat did you learn about the scientific methodFurther Thoughts, questions, connectionsMake sure this is thoughtful and thorough.
11 ReflectionThink of another toy or sport item you could experiment with, and identify one manipulated variable and one responding variable and explain how you would test it.
12 Big IdeaScientists carefully plan experiments to answer questions and solve problems.
