In Light and Shadows, children will unravel the secrets of science with simple experiments using easy-to-find ingredients. In this title in the Let's Experiment! series, children are accompanied by two characters: Professor Albert, who will teach them the scientific explanation behind each experiment; and Greg the Robot, who will guide them in their practice. They'll have a ton of fun learning what happens to light when it encounters different obstacles, how to build a periscope, how to create a rainbow, and much more! For each experiment, there is also a "mess-o-meter" for parents to know how messy the experiment can be, as well as the level of difficulty.
