A flow chart visually outlines the steps of the scientific method, including collecting information, forming a hypothesis, designing and conducting experiments, comparing observed and expected results, drawing conclusions, refining hypotheses, and reporting findings. Arrows connect each stage, with icons such as a microscope, beaker, and computer illustrating the process. A chart lists three scientific experiments, each showing an example question, the independent variable, and the dependent variable. The experiments cover fertilizer effects on plant growth, enzyme digestion time for milk, and how medium density affects light speed.
