2. If the student decides to add a control to the experiment, which of the following should the student do?

• 1. Grow at least three plants with each type of fertilizer.

• 1. Add a plant that receives no fertilizer.

• 1. Measure the height of the plants more frequently.

• 1. Record other non-pollinating insects seen during the time

• 1. Conduct observations on the same 15m x 25m area
