1. 10-1-12 Do Now Pick up your science journal from the back table.
Open it up to the Pellagra Big Idea section, and be ready to share what you think is the Big Idea of the Pellagra Story (Hint: Look back at the Key Question)

2. Big Idea
Scientists use the “scientific method” to help solve problems and answer questions.

3. Scientific Method Intro
Key Question: What is the scientific method?
Initial Thoughts: (Hint: what did Dr. Golderberger do?)

4. The Scientific Method Evidence 1-
The scientific method is the only scientific
way accepted to back up a theory or
idea. This is the method on which all
research projects should be based. The
Scientific Method is used by researchers
to support or disprove a theory.

5. The Scientific Method
The Scientific Method involves 7 steps: Scientific Question/Problem
2. Research the problem or question
3. Hypothesis
4. Materials
5. Procedures
6. Data, Observations & Analysis
7. Conclusion

6. The Scientific Method
1. Scientific Question/Problem - Develop a testable question or problem that can be solved through experimentation.

7. What is a “Testable Question?”
A testable question is one that can be answered by designing and conducting an experiment.

8. Testable Questions have two parts
 A manipulated variable (cause) – the variable that is changed.
 A responding variable (effect) – the variable that is being measured.

9. Forms of Testable Questions
Testable questions always have the same type of format…fill in the blanks with the variables.
What is the effect of __MV___ on __RV___?
Does changing ___MV____ affect ___RV____?
How does changing __MV___ affect __RV___?

10. The Scientific Method 2. Research the problem or question
- You do research and find out as much as you can about your topic.

11. The Scientific Method 3. Hypothesis A hypothesis is an educated guess.
You predict what you think the
answer to your question might be.
Write it in an “If…then…because…
statement.

12. Hypothesis Write a hypothesis from the testable question.
What is the effect of temperature on the height of a plant?

13. Hypothesis If temperatures rise,
then the height of the plant will increase,
because plants need warmth to grow.

14. The Scientific Method 4. Materials
List all of the materials you will use during the lab.

15. The Scientific Method 5. Procedures
Write the “logical steps” you will follow to complete the experiment.
Test your hypothesis.

16. The Scientific Method 6. Data, Observations and Analysis
Record your data (results) here.
Written Observations
Data Table
Graph

17. The Scientific Method 7. Conclusion – Restate hypothesis
State your data/Say what happened
Support/Explain: Use data to substantiate your hypothesis claim.
Reflection including scientific reasoning for the changes to be made in variables.

18. Evidence: Rocket Launcher
Brainstorm
In 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:

19. The Scientific Method
1. Scientific Question/Problem - Develop a testable question or problem that can be solved through experimentation.

20. What is a “Testable Question?”
A testable question is one that can be answered by designing and conducting an experiment.

21. Asking A Question:
What is the effect of _______________________ (changed variable)
On the _____________________? (Responding Variable)

22. Testable Questions have two parts
 A manipulated variable (cause) – the variable that is changed.
 A responding variable (effect) – the variable that is being measured.

23. Forms of Testable Questions
Testable questions always have the same type of format…fill in the blanks with the variables.
What is the effect of __MV___ on __RV___?
Does changing ___MV____ affect ___RV____?
How does changing __MV___ affect __RV___?

24. The Scientific Method 2. Research the problem or question

25. The Scientific Method 3. Hypothesis A hypothesis is an educated guess.

26. Hypothesis Write a hypothesis from the testable question.

27. Hypothesis If temperatures rise,
then the height of the plant will increase,
because plants need warmth to grow.

28. The Scientific Method 4. Materials
List all of the materials you will use during the lab.

29. The Scientific Method 5. Procedures
Write the “logical steps” you will follow to complete the experiment.
Test your hypothesis.

30. The Scientific Method 6. Data, Observations and Analysis
Record your data (results) here.
Written Observations
Data Table

31. The Scientific Method 7. Conclusion – Restate hypothesis
State your data/Say what happened
Support/Explain: Use data to substantiate your hypothesis claim.
Reflection including scientific reasoning for the changes to be made in variables.

32. Analysis Questions
What is the first thing 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?
Bailey Laronde is the most amazing person in the whole world<3

33. Summary
3-4 sentences
What did you think before about the scientific method
What did you learn about the scientific method
Further Thoughts

34. Reflection
Think of another toy you could experiment with, and identify one manipulated variable and one responding variable.

35. Rocket Lab
Scientific Question- How does the person affect the distance of the rocket?
Research the Question- how materials affect the rocket, background information about rockets and launchers.
Hypothesis- If (students’ name, MV) shoots the rocket, then they will have the greatest distance (RV) because (why you think that person will shoot the greatest distance).
Materials- person, rocket, meter stick, chalk, sidewalk, data table/ pencil

36. Rocket Lab Procedure- 1. Gather Materials
2. Designate starting line and direction of rockets.
3. Line up with rocket.
4. Launch rocket.
5. Measure flight distance of rocket.
6. Record data.
7. Repeat steps 3-6 with others in your group
8. clean up
