Dependent Variable(s)
Paragraph that describes the independent
variable and how it is measured. Important
points include:
Paragraph that describes the dependent
variable and how it will be measured. Important
points include:
• What is the IV?
• How will it be measured? What SI units will
be used?
• What are the IV groups that will be tested?
• How many times will you repeat the trial?
• What is the DV?
• How will it be measured?
• What SI (metric) units will be used?
Hypothesis
Short paragraph (1–4 sentences) that describes the formal hypothesis. Begin with an
“if…then…because…” statement and be sure to include:
•The specific relationship between the IV and DV
•An explanation based on background information
Constants
Control Group
List the parts of the experiment that must be
kept the same from trial to trial in order to
ensure that the results change due to the IV.
Be specific. If the volume of distilled water is
critical, then list the exact volume of distilled
water that you will use (e.g., 25.0 mL of distilled
water).
Describe the control group and explain why it
was picked as the control group. How does it
determine a baseline for comparison?
