Logical 5th Grade Science Fair Project Ideas You Should Try!

So, the date for science fair has been announced and you still haven't got a clue what you are going to present, right? Here is a list of some science fair project topics for 5th graders.
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.
