About the Author

Jodi Wheeler-Toppen is the author of more than 10 books for children and teachers. She holds a PhD in science education from the University of Georgia. She lives in Atlanta, Georgia, with her family. When she's not doing science with children or teachers, she's trying to build a whatcha-ma-jigaroo out of spare parts. It will surely be a remarkable device (if she can ever get it to work)!
