The Sun consists of a colorful teaching model, reproducible activity cards and background information. Explore the layers of our nearest star. From Corona to Core, each layer has been recreated. The model is made of resilient, non-toxic, EVA foam, with removable pieces that stimulate problem-solving skills and develop small motor skills. The book covers contain background information, activities, and extension ideas. Teachers can cut out the task card and use it in a learning center or as a group activity. The models are 10" x 14.5"x .75" thick.
