Question

Part I: Preparation
This experiment will be done using the following images and data. There are two cups, one EXPERIMENTAL and one CONTROL group. Each one will have four beans planted in it, and the EXPERIMENTAL cup will get half as much water as the CONTROL cup. all the other factors (like how much light and air they get) will remain the same.
State what you predict will happen in the Hypothesis section below.
Part II: Planting
1. In the CONTROL group there is gravel, soil, and four beans in the cup. 30 mL of water is added to moisten the soil. See Figure 1 below.
In the EXPERIMENTAL group, there is gravel, soil, and four beans in the cup. 15 mL of water is added to moisten the soil.
