(4) 4-6 21st Century Science series. Attempting to explain genetics research and then present some of the resulting ethical issues, this book accurately introduces chromosomes, DNA, meiosis, gene splicing, cloning, medical applications, and the like. But some of the text is dense, perhaps necessarily for the short-paragraph format. Photos and diagrams colorfully supplement the text. Glos., ind.

(4) 4-6 21st Century Science series. Broad in coverage and optimistic in attitude, this volume introduces subtopics ranging from the planets, stars, and galaxies to deep space probes and predictions of humans returning to the moon and exploring Mars. Also covered are telescopes, rockets, and the search for extraterrestrial life. Breadth and a highly segmented format result in rather superficial treatments, but the text is augmented with color photographs and diagrams. Glos., ind.
