Students will need access to the Gizmos app within ExploreLearning.com to use this material.

This is modified paperwork from what is readily available on their website. I have found their "paperwork" to not be user friendly, so I've created my own to use with my students.
I use this activity to help students learn about variables, not to learn about "ideal" plant growing conditions.
By the end of the activity students will easily be able to identify the Independent Variable and be able to analyze why it's important to control all other parts of an experiment.

This activity usually takes most students about an hour to complete.
