Discover our Solar System through 5 fascinating experiments. Using Patarev, a creative modeling clay, you'll be able to create scale models of the planets while learning about their unique features, before building a mini Solar System and observing how eclipses work. The instructions also show how to make a spinning top that, once spun, will help you understand and illustrate the Earth's movements, which give rise to days and seasons. A collection of discoveries that are as fun as they are educational, designed in collaboration with Jean-Loup Bertaux, an astronomer at the CNRS and a planetary scientist.
