Ursula Marvin didn’t have rocks in the head, but she had rocks on the brain! And meteorites and all sorts of neat science things. She was a girl who was told “learn to cook.” And instead, she decided to cook up some good trouble by finding moon rocks, meteorites and more in the harsh Antarctic landscape.
This picture book biography, Rock Star: How Ursula Marvin Mapped Moon Rocks and Meteorites by Sandra Neil Wallace and illustrator Nancy Carpenter is a fun introduction to a woman of science. Starting with a highlighted look at her childhood in Vermont, we then see the early years of her science career where she would explore, learn and add to the knowledge of the world about areas we knew little about. The bulk of the story is about the trip of a lifetime and how it would open our eyes to things only seen in the skies, but which, once in a while, would crash to the ground in the unforgiving landscape of ice, cold and storms. 
The illustrations are not simple or overly complex. They do have decent details and colors. The cover gives a good example of things, but there is more to them as well. They are fun, lighthearted, but allow you to see things are happening and they are dangerous. Overall, the story and text is actually cozy.
The theme of cbr18bingo Wheels is Traveling (I know it should have been Map, but I went eenie meenie and this got Wheels). Marvin would travel to the ends of the Earth. And these pieces of meteorites, and perhaps even the moon, would have to travel. Granted, not by wheels, but by flying. And in that became discoveries right along side the science that showed us how to use the wheel.
