Grandma Science is Sharon F. Johnson, Ph.D. She is a science educator with over 30 years of science teaching experience. She frequently performs science magic shows for her grandchildren and their friends; thus, the children started calling her, Grandma Science. This is her second children's book. Her first book, The Littlest Beach and The Great Coral Reef, takes children on a beach walk and snorkel and highlights reef conservation. She is also the author of Synergized Middle School Chemistry, a complete, introductory chemistry program for grades 5-8.
