Fifth Grade Science Fair Project Ideas 5th grade science projects enable kids to apply everything they've learned over the course of their elementary school careers in order to discover some pretty cool and new things about the world around them. In addition to setting up more sophisticated experimental procedures, 5th graders can analyze their results using more sophisticated math, and may begin to acquire an appreciation for large sample sizes and their ability to produce more reliable averages.
