The scientific method is a process of steps in order to get a conclusion. First, a scientist will observe something. It could be really anything. Then he/she will ask themselves a question. Like how does it do that? Or why does it do that?
Then they will form a hypothesis. This is where you will ask yourself what will be the outcome of the experiment.
Next you actually perform the experiment. If the experiment comes out as your hypothesis predicted, then you accept your hypothesis.
If not, you reject your hypothesis.
Of course, in science you just don't do one experiment. You do it multiple times and even with different circumstances.
Constants are factors that are not changed in the experiment. Since the experiment is testing different colors of light on plant growth, light color is being changed, and is therefore not a constant. Hope this helps! :)
Explanation: The two finches eat different kinds of food. The woodpecker finch eats insects and the large ground finch eats seeds. They do not compete for the same resources.
