Just a quick question??
Kids no matter what age come up with experiments all an their own?? Ask your child what he/she is interested in... And why?? And you will get a great... Unique... Science experiment all on your own!!! Just use the books for general science experiments format ...... Forget what other kids have done ..... Kids have the best imaginations out there..... Let them question and explore the world as they see fit.... And the science will follow smile
