Not only do I like animals and plants, I also like refrigerators and all the things inside them. So I was delighted to be asked to write How Do Refrigerators Work? (Chelsea House, 2009). I also wrote How Do Islands Form? for the same publisher.
If you think refrigerators are cool, you can find out about other objects and how they work in my book Everyday Things (Franklin Watts, 2001). (Did you know that people wrote with pencils for at least 300 years before the eraser was invented? The rubber eraser, that is. Before people invented this nifty device, they used wads of bread to rub out mistakes.) 
I have also enjoyed writing biographies for young readers, and was honored to be asked to write about diver Sammy Lee for Zaner-Bloser's "Voices" reading program. In addition to Sammy Lee, I also wrote Swimming the English Channel; Jesse Owens; Cuba; The Camels of Egypt; Traveling in South Korea; Wildlife on the East African Savannah; Hurricanes; Hyenas; Caves; Manatees; and a work of fiction entitled Caterpillar Countdown.
I am especially honored by my association with the Audubon Society and my history of writing for its environmental-education school newspaper Audubon Adventures. This program, which includes four full-color newspapers on different topics as well as a teacher guide and other materials, has been named one of the Top Ten environmental programs in K-12 schools. I have written articles and activities for this series, as well as teacher guides, on topics as diverse as dragonflies, habitat, backyard birds, and gray whales.
