Ouch! What Causes a Sunburn?

How I discovered that it’s all about UV rays

Hello, kiddos,
This is Professor Mordy Maven, Thinker, Wonderer, and Figure-Outer of all things Science-ish. What that basically means is I try really hard to figure stuff out. I do the hard work so you don’t have to!
Summer’s finally here, and I couldn’t be happier! No classes means I have more time to do my own research. After all, as much as I learn at school, I always learn a lot more on my own. Like the time I learned that the most common form of color blindness is red-green but there’s also blue-yellow color blindness, called tritanopia! And aside from all of my own experiments, I also love getting the chance to see my old summer friends. I was especially looking forward to seeing my good friend, Pinny. Or as we call him, Pale-Pale-Pinny. That guy is so pale that when his mother puts on white bed sheets she can’t even find him! So imagine my surprise when a guy claiming to be Pinny walks over to say hi to me. This guy is the same size as Pinny. His voice sounds like Pinny. The tag on the inside of his T-shirt actually says Pinny. But, but, but…. he’s bright red! And not only that, parts of his skin are peeling off. Yuck!
