(4) K-3 Illustrated by Michael Koelsch. This introduction to dinosaurs contains the usual facts and speculation about what these prehistoric creatures looked like, how fossils were formed, and why they disappeared. What sets this book apart from other, similar volumes, are experiments and activities that demonstrate, among others, how dinosaurs may have communicated and how dust affects the atmosphere. The accompanying color art tends to be silly.

(4) 4-6 Illustrated by John Dykes. This collection of facts about marine life, tides, and ocean currents has photographs of Bill Nye on every page. Fans of the television show will recognize the features "Try This!" (activities) and "Check it Out!" (factual asides), though the experiments suggested are disappointingly routine or impractical. The accompanying color illustrations are quieter than the chatty text.
