Use shapes to block light and make shadows on cave walls! Choose from squares, rectangles, circles, triangles, semi circles, and parallelograms to create just the right object. Then match the mysterious outline on the wall by moving the object to make the shadow bigger or smaller. When the shadow is just the right size and shape, see what the cave drawings reveal! With a magical mysterious cave and the chance to create your own shadows and cave drawing designs, Shadow Cave is a cozy and creative exploration of the math and the science of shadows. Families can also choose to play in English or Spanish!
