Question

drag and drop the items to accurately match them to the correct variable. experiment 1: how do the different chemicals in fertilizer affect plant growth? the variable is how the fertilizer affect plant growth depending on the different fertilizers. experiment 2: how long does it take three different types of enzymes to digest a liter of milk? the variable is the time needed to digest the milk. length of the enzyme, outcome (dependent), test (independent), three different types of enzymes, control, plant types, length of time, plant grows, types of fertilizer, three different types of milk

Explanation:

Experiment 1:

Step1: Identify independent variable

The factor being changed is types of fertilizer, so the independent variable is types of fertilizer.

Step2: Identify dependent variable

The variable that responds to the change in fertilizer and is being measured is plant growth, so the dependent variable is plant grows.

Experiment 2:

Step1: Identify independent variable

The different elements being tested are three different types of enzymes, so the independent variable is three different types of enzymes.

Step2: Identify dependent variable

The outcome being measured is how long it takes to digest a liter of milk, so the dependent variable is length of time.

Answer:

Experiment 1 - Independent variable: types of fertilizer; Dependent variable: plant grows
Experiment 2 - Independent variable: three different types of enzymes; Dependent variable: length of time
