Author Description

In each two-page spread, a student is introduced to a science concept. 12 total units, 3 each on biology, chemistry, physics, and earth science. Each chapter has self-tests. Suggestions for do-at-home experiments. The original books have been out-of-print for years and nearly impossible to find; this is a reprint from Emmanuel Books (who has full permission to reprint). The reprints are coil bound with a clear plastic cover.
