Need help with thesis statement?

Question

i am writing an essay on the effect of bean growth under different color lights and i have no idea what to say in my thesis statement...
i would love some help

Answer 1

The effects of different colored lights on bean growth are (blank), (blank), and (blank). If you find three effects, then this sets up your paper's form throughout. Put the most important effect last as a built up.

Answer 2

Here's my suggestion.

You will need at least four samples. One to grow under daylight as a control and then one to grow under each of the primary colours in light (i.e. red, green, blue).

You are going to want to track rate of growth, sizes of plants, effect on leaf size and shape.
