It’s a handmade science kit and the kit contains basswood plywood, screws, foam balls, rubber band, etc. Usually, we are using it in schools, classrooms, and home science, etc. Children can follow the instructions to make this model, and can also bring their own colored pens to color the model. But it does not enrich the knowledge of the sun, the earth.
Students can rotate the model and observe how the sun, the earth, and the moon work. In addition, students can also illuminate three planets with a flashlight to observe the influence of the moon on the earth.
