2. Part 1: Designing the Experiment My Question:
______________________________________
_______________________________________
Part A: Things I could change or vary:
Part B: Things I could measure or observe: 2

3. Identifying Variables
I will
change:
I will
measure or observe:
Place one item from
Part A here
Place one item from
Part B here
I will not change these things:
(These things will control my experiment):
Place remaining items from Part A here.
I will not measure or observe:
Place remaining items from Part B here. 3

4. Asking a Testable Question
(Refining my beginning question)
When I change _________________________________: What happens to ________________________________?
What I will change
What I will measure or observe
Write the question that will guide your experiment:
__________________________________________________________________________________________________________________________________________
Predictions
(List 3 possible outcomes: Increase, Decrease, or No Affect.)
Based upon my question, I predict: 1. 2. 3.
Choose a prediction and generate a hypothesis statement:
Hypothesis:
If_______________________________________
then_____________________________________
because___________________________________. 4

5. The Procedure
(Others should be able to follow the way you set up your controlled test.)
Procedures

6. What I will change or vary (independent variable):
Number of trials I will conduct or amount of samples: ______
The data I will collect by measuring or observing
(dependent variable):
What I will measure or observe
How I will collect the data:
_____________________________________________
How I will record the data (for example: table, chart, picture): ____________________________________________________________________________________________ 6

7. Part 2: Conduct the Experiment
Data Collection:
What I will change (independent variable)
What I will measure or observe
(dependent variable)
Record your Data:
This chart is intended as an example to help get you started.
You may design your own chart to fit your experiment.
Results
(Use metric measurements.)

8. Y axis X axis Graphing your Results
Which type of graph is best- line graph or bar graph? ______________
Graphs should reflect the trials and the average of the trials.
What I measured or observed
(dependent variable) Y

(Note: Both axes will need to be labeled and the appropriate scale marked) 8

9. Title of Graph: __________________________
Y-axis: ______________________________________
X-axis: ______________________________________ 9

10. Explain your Results
1. Looking at your graph, describe your results.

3. Compare your initial predictions and the actual results from your experiment. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
4. Explain real world uses relating to the results of your experiment. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
What are some questions that you have for further investigation?
