Plan a test to determine the best paper towel. Will you test absorbency or strength or …?
Problem Statement: One testable question that can be answered by performing an experiment.
Hypothesis (“If (I do this) then (this) will happen.”)
Test(Independent/manipulated) Variable Outcome(Dependent/responding) Variable or what
you plan to measure and how Control(Constant) Variables or all the factors to be
kept the same in the experiment List of materials you think you will need

Finalize the Investigation Write your procedures or the steps you will follow in your experiment. Each procedure step needs to be numbered. Each step needs to begin with a verb. Check procedures to insure that all variables
are kept the same (constant) except the one you are testing (independent/manipulated).
Collect the materials needed for the experiment.
Create data tables.

Conduct the Experiment
Start the experiment to test your hypothesis. Observe and record the quantitative data (numbers or
measurements) collected during the experiment on a data table.
Repeat the experiment three or more times to confirm results.
Graph your data from all trials. (Dry Mix) Restate your data in a narrative form as the Results.

Drawing Conclusions What was investigated? (Describe the problem
statement.) Restate your hypothesis, and tell if it was supported(true) or not supported (false). What were the major findings? (Explain your
results.) Look at everything that may have affected your
results. What possible explanation can you offer for your findings?
