Things That Float and Things That Don't

Illustrated by Anna Raff
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.
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.

Anna Raff is an award-winning illustrator of many children's books. She has an MFA from the School of Visual Arts and lives in New York City.
