Informative. This wasn't the best pick for a read aloud with my boys because they weren't very interested, I was hoping they'd like to learn more after our somewhat recent trip to the Hoover Dam. Not so much.

I enjoyed it, and I think kids who enjoy non-fiction would like it better. The pictures and diagrams were nice.

Amy: I liked it because it taught me all about energy.
