Earth in Space [PDF ebook] 

Meet Earth, the colorful planet that we call home! Earth is here to introduce readers to many of its features, including layers, seasons, rotation, tilt, orbit, and location in the galaxy. Students will dig into Earth’s crust, dive into the hydrosphere, and blast off into the Milky Way to learn about what makes Earth unique. Extend the learning with the Explore the Phases of the Moon activity found in the back of the book.
