8. Warm Up-
Did you like designing your own experiment yesterday?
Explain your answer.
“Yes, I did like designing my own experiment because…”
“No, I did not like designing my own experiment because…”
What did you find difficult? Why?

9. Objective

 Students will be able to describe what they know
about scientific method and identify the controls and
variables in a given problem.

10. Scientific Method Vocab
Review

 Cut out the words and definitions
 Match the word to the correct definition
 Raise your hand to be checked
Once checked, glue the matching word and
definition into your notebook

11. Vocab Review

 Variable- An unknown; a part of the experiment that changes
 Constant- A part of the experiment that does not change
 Control-The part of the experiment that the independent variable is left out- the
one thing you are testing for is not included; used to compare the
results; may be part of the test or may be from research
 Independent Variable- Change that occurs in an experiment that is directly
caused by the experimenter
 Dependent Variable- May be part of the test or from research; change that occurs
due to the independent variable
 Hypothesis- An educated guess from research to try to answer the problem or
question given; testable
 Problem- A question to be answered

12. Controls and Variables


13. Homework

 Patty Power Problem

14. Warm Up-
Distinguish between an independent variable
and a dependent variable. Give an example.

15. Objective

 Students will be able to differentiate between
independent and dependent variables, and use them
to write a hypothesis.

16. Lisa Simpson
Homework

 Control- untreated hair
 Independent Variable- Rogooti hair product
 Dependent Variable- the speed of hair growth
 Problem- Does Rogooti affect the speed of hair
growth?
 Hypothesis- If Rogooti affects the speed of hair
growth, then the treated hair will grow faster
because the hair product will promote hair growth.

17. Patty Power Homework

 Control- Group B
 Independent Variable- New Sauce
 Dependent Variable- Amount of Gas
 Conclusion- the new sauce appears to work
 Why do you think 8 people in group b reported
feeling better?
 Placebo Effect

18. Controls and Variables


19. Warm Up-
What do you think is a control group? What do
you think is an experimental group? Give an
example for each

20. Objective

 Students will be able to differentiate between
independent and dependent variables, and use them
to write a hypothesis.

21. Controls and Variables

 Go over

22. Reminder

 Control- what you are testing against to see if what
you are testing will work; independent variable is
left out
 Independent variable- what you are testing; the
change you are making in the experiment
 Dependent variable- DEPENDS on the independent
variable; what you are measuring

23. Writing a Problem

 Always in the form of a question
 Includes the independent and dependent variables
 Does _________________ (independent variable)
affect ____________________ (dependent variable)?

24. Writing a Hypothesis

 Included the independent variable and the dependent
variable
 If ________________ (independent variable) affects
_______________ (dependent variable), then _____________
(what you think will happen) because
_______________________________ (explanation).

25. Gathering information
from Scenarios

 Read the scenario
 Identify
 Control
 Constants
 Independent variable
 Dependent variable
 Experimental groups
 Write the problem for the scenario
 Come up with a hypothesis for the scenario

26. Homework

 2 Scientific Method Problems

27. Warm Up-
Write a problem and form a hypothesis for the situation.
Naomi thinks she came up with a special ingredient to make
gum last longer. She has asked 10 of her friends to help her
out. She gives 5 people the old gum and 5 people the new
gum.

28. Objective

 Students will be able to differentiate between
independent and dependent variables, and use them
to form a hypothesis.

29. 
 Marshmallow Muscles
 Control- Spongebob
 Independent Variable- Muscle Cream
 Dependent Variable- amount of marshmallows lifted
 Conclusion- claim is not supported
 Microwave Miracle
 Hypothesis- If the microwaved food affects the time it takes the fish to
complete the maze, then the fish will complete the maze quicker
because they are now smarter.
 Control- fish that ate the regular food
 Independent variable- microwaved food
 Dependent variable- time it takes to complete the maze
 Conclusion- special food does not appear to work or make the fish
smarter
