Middle school kids are old enough to understand the significance of science fair projects. They can even come up with their own ideas for such projects. However, they need help from parents or teachers for implementing their ideas. Though parents are not expected to make a project for their kids, they must guide them, whenever required.
While choosing a science fair project for 5th graders, one must understand that complexity of the project is not the deciding factor for good grades. Many students present the simplest scientific facts in the most interesting way and get away with A grade.
