"Alice and Oliver know that the Sun is very important. The Sun gives us light and life and without it, none of what they can see through their window would exist. In this engaging book, the children will explore the mysteries of our very own star! Inside, Sun-related topics--from its immense size and power to solar eclipses, light speed, and more-- are covered. Fun activities at the back of the book reinforce the information and let kids test what they've learned. Includes a helpful parent's guide too."--
