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.
THE REVIEWS ARE IN!
★ "Adler shows his customary skill for explicating mathematical concepts in this smart exploration of floatation and density."-Publishers Weekly (starred review)
★"It's rare to find a picture book that uses simple, hands-on activities so successfully, leading young children to a fuller understanding of a scientific concept."
"—Booklist, Starred Review
"This title supports the Common Core State Standards that focus on measurement skills, interpretation of data, and incorporation of key ideas and details in the text. Recommended for math collections in public and school libaries and classroom shelves."-School Library Journal
CCSS ACTIVITY FROM Booklist
"This book directly addresses readers and asks them to try putting different objects in water. Then Adler introduces various physics concepts, explaining why objects sink or float. Have students try the experiments in the book. After determining whether the objects sink or float, have the students go back in the text to find the explanation of why that's the case.
