Second Grade Science Projects (79 results)

Science Buddies' second grade science projects are the perfect way for second grade students to have fun exploring science, technology, engineering, and math (STEM). Our second grade projects are written and tested by scientists and are specifically created for use by students in the second grade. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, second graders can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.
