This appealing site by Kapili.com has recently undergone some major changes, including updated content and its own URL. With lots of information and neat photos, this is a great site to learn about how to study and classify life forms, ranging from cells and microbes to plants and animals. Visitors can be guided through the site tour, browse, or search for specific topics. Even though there is only one quiz available in the Activities section, the site is interesting and informative.
