Perhaps the most successful way to truly grasp an important science concept is to see it in action. This awesome book invites readers to put on their lab coats and transform into scientists. They'll perform several simple experiments by following step-by-step instructions, accompanied by helpful images, and are encouraged to reflect on their results. By each experiment's end, they'll have discovered an essential principle of science for themselves in an entertaining and unforgettable way, such as creating rainbow-colored celery with food coloring to show how water moves through plants. Additional activities provide for more learning opportunities--and another chance for fun!
