The Arithme-Tickle duo is back--this time tackling science--with riddle-rhymes about everything from dinosaurs to gravity. The illustrations incorporate clues about the riddles, and the answers themselves are subtly included for anyone who needs a little extra help. J. Patrick Lewis"s clever word puzzles and bestselling illustrator Frank Remkiewicz"s engaging illustrations harmonize perfectly in a fun, informative book that will inspire even reluctant young scientists to explore the world around them. Endnotes expand on Albert Einstein, the solar system, and other fascinating scientific topics.
