Explore your environment with our Life Science 3-book BUNDLE. Students begin by studying the different kinds of Ecosystems. See how food chains work by creating your own food web. Look through a microscope at the tiny world of microorganisms. Next, delve deep into ecosystems with Classification & Adaptation. Classify animals by their kingdom all the way down to their species. Then, do a case study on the adaptations of the koala. Finally, take a look at the building blocks of life with Cells. Compare single-celled and multicellular organisms. Look at the big picture by seeing how cells become organisms. Each concept is paired with hands-on activities and experiments.
