Question

a student wants to see if plants prefer rainwater or tap water better. they fill a seed tray with soil, put one bean in each pod, and water half the pods with rain water and half the pods with tap water once per week. what are the independent and dependent variables in this experiment? o independent: soil dependent: type of water o independent: type of water dependent: number of beans germinated o independent: type of water dependent: type of beans o independent: type of water dependent: number of beans

Explanation:

The independent variable is what the experimenter changes or manipulates. Here, the type of water (rain - water or tap - water) is being changed. The dependent variable is what is being measured as a result of the change in the independent variable. In this case, the number of beans that germinate is being measured.

Answer:

Independent: type of water; Dependent: number of beans germinated
