Fourth Grade Science Fair Project Ideas

Building off of what they learned in 3rd grade, 4th graders add a new level of sophistication to their 4th grade science projects. In addition to describing data quantitatively, kids begin to use their observations to formulate scientific arguments and engage in scientific debate. 4th grade science fair projects may involve kids going beyond testing a hypothesis—young scientists can be encouraged to use their results to make predictions about what might happen when the experiment is expanded to test new variables. Education.com's selection of fourth grade science fair project ideas are carefully written with 4th graders in mind, giving them the tools they need to effectively learn about the world around them by pursuing the answers to their questions in a methodical way.
