It can be surprising which objects float and which dont. 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?

Adlers clear, concise text, paired with Anna Raffs delightful illustrations. Activities that demonstrate the properties of flotation are included.
