Do your readers wait until the last minute to start their science project? Don’t worry, award-winning author Robert Gardner has everyone covered. Each experiment in this book follows the scientific method, and can be completed in an hour or less. Readers will explore leaf anatomy, use a tree’s shadow to measure its height, and find out how old that tree is. Most experiments also include ideas for science fair projects, in case readers have more time than they originally thought.
