The document outlines the scientific method process of conducting an experiment. It discusses forming a research question about how fertilizer influences plant growth and generating a hypothesis. An experiment is proposed that tests different amounts of fertilizer as the independent variable on plant growth as the dependent variable, while controlling other variables like sunlight and temperature. The experiment would collect data on plant growth with different fertilizer amounts and draw a conclusion about how the fertilizer influences plants.
