theory hypothesis variable control - Hypothesis

An experiment is a specific test of a:

true false - False

Based on your experimental results, detergent (soap) exposure does not negatively impact plant growth

type of fertilizer used type of plant used amount of fertilizer given to plants height of plants

Consider the following hypothesis, "Does fertilizer make a plant grow bigger?" Which of the following would be an independent variable in an experiment designed to test the hypothesis?

Marigold, plastic pot, hyponex soil, no exposure to dawn detergent Chamomile, plastic pot, hyponex soil, no exposure to dawn detergent Chamomile, terra cotta pot, miracle-gro soil, exposure to dawn detergent Marigold, terra cotta pot, miracle-gro soil, no exposure to dawn detergent Marigold, terra cotta pot, miracle-gro soil, exposure to dawn detergent 1. 5 - 5.5 cm 2. 3. 3 cm 4. 5. 4 - 4.9 cm
