Scientists conduct experiments to gather information that will prove or disprove their hypotheses. Chapters explain how experiments are set up with controls and variables, how to write up observations, ways to accurately record data for analysis, and the importance of repeating experiments and comparing results. An example experiment illustrates step by step how students can go about running an experiment for their own science project.
