Home, sweet home! This title is about Earth, the planet we live on! Earth is one of the rocky planets in our solar system, but it is the only one we know of that can sustain life. Learn about how the Earth rotates on its axis, giving us day and night, and how it orbits and is warmed by that giant star we call the Sun. This book will allow students to make observations to determine the effect of sunlight on Earth's surface.
