Linking science to literature is a good way to teach. So many books are available to help you do this. You want to make sure your young students understand, however, just because it's in a book, it may not be a true fact. This can lead to some time spent researching, fact checking, and verifying.
Joanna Cole's The Magic School Bus series is fact-filled fun for students to read the text, peruse the sidebars, and scan the pictures while learning science. Because of all the sidebar information and comic-book type comments in the graphics, however, it's not the best choice for a read-aloud, in my opinion.
Seymore Simon's books are a wonderful addition to your classroom library. He writes nonfiction books as well as fiction stories on a wide variety of science topics. A few of his books are in Spanish.
