Investigation Planning and Analysis

Mr. Anderson's video tutorial explains how to plan and carry out scientific investigations. It covers identifying phenomena, defining the purpose, gathering evidence, and creating a plan. The video includes two example investigations: one with taped eggs to determine their contents and another with cars on a ramp to measure roll distances. The tutorial emphasizes the importance of setting up investigations properly to gather meaningful data.
