ESA Space for Kids
ESA Space for Kids is the European Space Agency’s children’s site about space, with reading, games, things to do and multimedia.
A cartoon character named Paxi guides explanations of planets, stars and Earth. Separate sections for reading, games, making and video can fill a quick visit or a longer space-themed afternoon. After a Paxi animation, a child could draw or model the idea in their own words.
