A student wants to know which part of his local beach contains the most turtle nests during nesting season. He makes a prediction to investigate based on his observations and plans his experiment. He performs the experiment to collect data. Once his experiment is completed, he gathers his evidence and analyzes it to form a conclusion.What part of the scientific method is needed to form a better hypothesis for this investigation?

Suppose you are investigating the effects of infrared light on plant growth. After growing many plants and recording your measurements, you form the following : plants that are exposed to infrared light will grow larger and faster than plants in normal sunlight.
