Unit 1 Study Guide

I want to see if different colors of light help plants grow better. I am going to take four plants (all the same type) and set them up underneath different lights. One will be a white light, one will be red, one will be blue, and one will be green. Everyday, I will water them the same amount at the same time. I will also record how high each plant grows for two weeks and then look at my results. What is the independent variable?

What is/are the constant(s)?

I want to see how taping my thumbs will affect my time it takes to button up a shirt. I will test the same person - they will do three trials buttoning up the same shirt with their thumbs taped to their palms. Then I will do three trials where their thumbs are not taped up. I will average the time in seconds that it takes to button up and shirt with their thumbs taped and without their thumbs taped.
