Nathan is conducting a science experiment for their school project. They are trying to understand the relationship between the amount of sunlight a plant receives and the growth of the plant.

What is the difference between independent and dependent variables in this investigation?

What is the relationship between the IV and DV?

• The amount of sunlight is manipulated by Nathan, while the growth of the plant is measured or observed. Plant growth is affected by the amount of sunlight.

• The growth of the plants is manipulated by Nathan while the amount of sunlight is measured or observed. The sunlight is not affected by plant growth.

• The growth of the plants is manipulated by Nathan while the amount of sunlight is measured or observed. The sunlight is affected by plant growth.

• The amount of sunlight is manipulated by Nathan, while the growth of the plant is measured or observed. Plant growth is not affected by the amount of sunlight.

Priya, Luna, and Aiden are conducting an investigation. Why is it important for them to have a control group and an experimental group in their investigation plan? Select ALL that apply.

• To compare the results from the control group to the results from the experimental group.

• To compare the results calculated by hand to the results calculated by a computer.

• To establish if there is a cause-and-effect relationship between the independent and dependent variables.

• To establish if there is a correlational relationship between the independent and dependent variables.
