FORMING THE QUESTION AND HYPOTHESIS
What do you believe will happen?
Hypothesis: A testable hypothesis that clearly leads to your investigation. The hypothesis is
written as an “If...then” statement, with a cause (manipulated/independent variable) and effect
(responding/dependent variable) sentence.
Why do you think it will happen?
Background is relevant information from your personal experiences, along with
scientific research (i.e. science concepts) that connect to your question and hypothesis.
2
1
3
Define the concept and describe the relationship between each science concept on the triangle
This information supports your hypothesis, and should be written in paragraphs.
DESIGNING THE INVESTIGATION
How will you set up your experiment? Draw what your experiment will look like. Be sure to
label all materials and equipment!
Experiment details
Manipulated/independent
Variable
Control
Number of trials
Constants
What kind of data are you going to collect?
Quantitative
(Responding/dependent
variable measurements)
Qualitative (observations)
Materials: (List with amounts)
How will you do the experiment?
Procedure: List the steps (use bullets or numbers). Be sure to use all items on your materials list, and
explain how each will be used.
COLLECTING AND PRESENTING DATA
Attach your data table and graph.
What qualitative data did you record?
ANALYZING AND INTERPRETING RESULTS
Be sure to write this information in paragraphs.
What did you find out in your investigation?

Restate the hypothesis. Does the data support or reject your hypothesis?
Why did it happen?


Using your graphs, identify any observable patterns. Also use science terms from the
background information to make inferences that explain why the hypothesis was supported or
rejected.
Show the relationships between your science terms and explain how they connect to your
investigation.
How could your experiment be improved?




Are there sources of human error or limiting factors? (Sample size? # of trials? time period of
lab?)
If you did this experiment again what would you change?
What if you had unlimited resources, how could you test your hypothesis?
Is there a follow up experiment that you could do now?
