(Proceed with caution: It's really difficult to thoroughly research superheroes, so I depended on my uncle, my dad, and not-so-scholarly sources from the Internet to educate me. In other words, please send me a comment to let me know if I've messed something up royally. Also, this post is BY NO MEANS saying that any of these characters consistently feature quality science.)
1. Metal Men: A group of robots who each represent -- and are made of -- a single metal. The characters were Gold, Iron, Lead, Platinum, and Tin.
Lessons learned: Each character took on features of their namesakes. Gold could be pounded very thin and was a good conductor, Iron was strong, Lead could stop radiation, Mercury could liquify (and was hot headed), and Platinum could stretch or flatten. As far as I can tell, Tin was rather useless. One Metal Men website (which is fairly educational) quotes him as saying, "I turn to powder at 200 degrees centigrade but I'll do my best to be worthy of you all, if you'll give me a chance."
Lessons learned: There are things called "atoms" that are really small. Mass is determined by more than just size. Large amounts of energy can be produced by atomic (nuclear) power.
3. Metamorpho: This superhero has the ability to embody any element found in the human body or any combination of those elements.
Lessons learned: Different elements have different properties and can be combined. Metamorpho also offers readers a glimpse of which elements reside in the human body. (Here is some of what those elements do.)
Lessons learned: There are different kinds of suns (stars), gravity can vary on different celestial bodies, and the sun can serve as an energy source.
5. Ant-Man: Another small guy, like the Atom, he is able to shrink down to the size of an ant while maintaining strength proportional to his regular size.
Lesson learned: Ants are crazy strong for their size.
*6. The Flash: Again, you're probably familiar with this guy but he can get some extra credit for his ability to create sonic booms.
Lesson learned: Sonic booms occur when an object moves through air faster than the speed of sound.
Got any more instances of superhero science? Let me hear about them in the comments section below.
