This sentence ain’t got not good grammar.

5. What you change in the experiment
DEFINITION #1
Independent Variable
What you change in the experiment
(to make life easier for your students, you may want this “change” to be measurable - i.e. weight, mass, volume, height, etc..)

6. The result from the change you made
DEFINITION #2
Dependent Variable
The result from the change you made
(this variable, also known as data, “depends” on your independent variable and, again, should be measurable)

7. The INDEPENDENT VARIABLE and the DEPENDENT VARIABLE are close relatives and can be found throughout the following steps of scientific inquiry: QUESTIONS HYPOTHESIS DATA TABLES and GRAPHS

8. All scientific experiments begin with simple questions….
It is this sense of inquiry that ESP begins its journey….
…with a QUESTION

16. Question: Let’s try an example...
How does the length we pull backwards on the toy car affect the distance it will travel?

17. Can you identify the IV and DV?
How does the length we pull backwards on the toy car affect the distance it will travel?
Can you identify the IV and DV?
IV = length we pull backwards on the toy car
DV = distance it will travel
LOOK FOR THESE PHRASES THROUGHOUT THE EXAMPLE

18. Hypothesis 
If the length we pull backwards on the toy car is increased, then the distance it will travel will decrease.

19. Length pulled backwards on the toy car Distance it will travel (DV)
Data Table
Length pulled backwards on the toy car
(IV)

20. Distance it will travel Length we pull backwards on the toy car
The effect of the length we pull backwards on the toy car on the distance it will travel
Distance it will travel
(DV)
Length we pull backwards on the toy car
(IV)

21. can be seen throughout the entire experiment
The phrase
“length we pull backwards on the toy car”
and
“distance it will travel”
can be seen throughout the entire experiment

23. Procedure
List a 3-step procedure that would make this a valid (fair) investigation.
What am I going to change? (IV)
How will I change it? (Include all of the experimental variables from the data chart)
What data will I collect? (DV)

24. Conclusion Restate the hypothesis
Write a possible conclusion statement for this investigation.
Restate the hypothesis
State whether your data supports or does not support the hypothesis
Include all of the data (IV and DV) from the graph
