1. Complete Scientific Method Review Sheet

a. Be able to identify...

i. Manipulatedllndependent Variable (MIX)- The

independent/manipulated variable is what I change

between my two groups or the thing I am testing.

ii. Responding/Dependent Variable (DRY)-The

responding/dependent variable is what has been fone,

the results you will see at the end.

b. Write a testable question. (rewrite the problem statement)

i. Must be written in the correct format... What is the

effect of

c. Identify constants. Things I can't touch...they do not

change.

d. Write a hypothesis.

i. Must be written in the correct format. If...(independent

variable, then...(dependent variable).

2. Know how to construct a bar graph.

a) There must be a space between your 1st bar and the Y axis.

b) Your bars must be equal width

c) You must have equal spaces between bars

d) Axis must be labeled including units

e) Your graph must have a title.

f) The Y axis must have a constant interval (each line on the Y axis

must have the same value)

g) You should use approximately 75% of the available graphing

space.

3. Construct a Line Graph

and following

â€¢ Be able to list ordered pairs. (x,y) format
