In this study of Physical Science, you'll be introduced to the stunning world you live in, as well as the universe around it. From the composition of air to icebergs to astrophysics, you will recieve thorough lessons in each element of the physical world. Sixteen modules are included, that are designed to be completed in a total of 32 weeks time, though the course can be adjusted to your own needs. "On your own" questions throughout the text are designed to help cement concepts, while "Study Guide" questions prepare for tests. All information that must be memorized is centered and in bold text, and all definitions and important terms are also bolded. Experiments using only household equipment, graphics, illustrations, charts and other visual representation of various concepts are also included for maximum clarity. This second edition is newly updated, with more color illustrations and higher-quality drawings. Fuller responses to student questions; easy-to-perform (and more engaging!) experiments; in-text graphics for online resources; additional material for advanced learners; and an extra test booklet (sold separately) are also new improvements. Topics include the atmosphere; hydrosphere; weather; structure of Earth; environmentalism; physics of motion; Newton's laws; gravity; and astrophysics. 510 pages, hardcover. Due to these changes, editions should not be mixed.
