3rd Grade Science Fair Projects

For their 3rd grade science projects, kids begin investigating the answers to their questions much like actual scientists would. Instead of simply collecting qualitative data (describing what they observe), 3rd graders graduate to collecting and presenting quantitative data by measuring their results with increased accuracy, communicating their findings in simple charts and graphs, and describing their observations in written prose. Education.com's collection of 3rd grade science fair projects give kids the opportunity to apply their newly acquired skills to thinking critically about the world around them while having serious fun in the process. Browse our collection of third grade science projects and experiments by using the boxes to the left to filter by topic, and find that exciting science project your child will be sure to love.
