Ages 5 to 8 years. This extraordinary book shows in a simple way how the Sun's light and warmth affect the Earth. Children will be amazed to learn that the sun is actually a star, and that its position and distance from the Earth cause day and night as well as changing weather and the seasons. Simple, brief explanations also describe the Earth's rotation and tilt, the Earth's two poles and the equator, a solar eclipse, how plants make food from sunlight, and how sunlight colours our world.
