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.
For 8th grade students.
