Polarity

This is one of the easiest and also most effective science labs I did all year with my students. Very user-friendly, and the beauty of it is that its simplicity allows students to see that science is all around them, and that it has eluded them this long only because they weren't trained to ask the right questions. This could work in lower grades as well.
