This is short and sweet since I have very little time to cover nuclear science with Acids and bases in a Physical Science class. When I get to the part where the slide asks whether an acid is worse or a base, most kids will say acid because of the social stigma of acids. I have a story to tell them about was almost severely burned with a strong base. It was in a hospital kitchen no less! I usually follow this up with a simple acid base lab using cabbage, litmus, and universal. I also usually show a movie about Einstein's contribution to the development of the atomic bomb or about Chernobyl for the nuclear section.
