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 how magnetic force works, how to make and use a compass, build a circuit, 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.
