The height of the plant under different types of light should be measured.
In an experiment, we seek to determine how a cause leads to an effect. In this case, Susie is trying to know the effect of different types of light on the growth of a plant.
It is true that the easiest way to measure the growth of the plant is to look at the height of the plant. This shows us the extent to which the plant grows.
Let is recall that in this case, the height of the plant is the dependent variable while the kind of light is the independent variable. As the kind of light is changed, the height of the plant which is an indicator of the growth of the plant changes also and this is the crux of what Sarah is studying.
Thus, the type of measurement that Susie should make on the plants to determine how they did in different types of light is to measure the height of the plant under the different types of light.
