It can be surprising which objects float and which don't. An apple floats, but a ball of aluminum foil does not. If that same ball of foil is shaped into a boat, it floats! Why? And how is it possible that a huge ship made of steel can float? Answering these questions about density and flotation is David A. Adler's clear, concise text, paired with Anna Raff's delightful illustrations. Activities that demonstrate the properties of flotation are included.
"Adler shows his customary skill for explicating mathematical concepts in this smart exploration of floatation and density. Several experiments allow for a hands-on approach: Adler suggests filling a sink with water and testing whether different objects float, as well as using modeling clay to demonstrate how shape is as important a factor as density. Raff’s pastel palette and cheerful characters keep the mood light and pair well with Adler’s explanations, which are clear without being dauntingly technical." —Publishers Weekly (starred review)
David A. Adler is the author of many children's books, such as Mystery Math: A First Book of Algebra and Fractions, Decimals and Percents. He lives in New York.
