Vibrant, full-color photos and carefully leveled text will engage beginning readers as they learn about the visible light spectrum and how sunlight reacts with particles in the air to affect the sky's color. A picture diagram shows how light waves scatter when they reach Earth's atmosphere, while a picture glossary reinforces new vocabulary. Children can learn more about the sky and Earth's atmosphere online using our safe search engine that provides relevant, age-appropriate websites.
