What’s It Like? With CK-12, students can create an account by entering their email address and a password. They can then explore the site, which is divided into Mathematics, Science, and More. Mathematics includes subjects from arithmetic to trigonometry and statistics. Science covers all the bases: biology, chemistry, and physics, as well as life, earth, and physical science. The More section offers history, technology, and economics. Within each subject, you can click on a circle, each of which contains a number of Concepts (short, chapter-like lessons). For example, if you click on Phases of Matter, you will be given a list of topics that includes evaporation, sublimation, and solutions. Within these topics, you can choose from a series of modalities: Read, Practice, Video, Real World, and more.
