In my class, we use this worksheet as we do a grass experiment. That experiment runs as follows:
As a class, we determine what variables we should control between two cups of grass, one which will be grown in the sun and one in a cabinet. Things we control: seed type, seed amount, soil type, soil amount, container type, water amount, etc.
We take turns watering the grass and each week we record data. After two weeks we draw conclusions.
P - Problem
I - Gather Information
H - Hypothesis
T - Test Hypothesis
D - Data Analysis
C - Conclusions
This worksheet can be EASILY modified for any experiment that you are doing and want the students to take a note of all steps of the scientific method!
You could even use it to take notes on the steps of the scientific method if you wanted.
