While trying to cross a moat, Archimedes the Goat and Skinny the Hen learn why objects sink or float.

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.

Introduces the concepts of floating and sinking by following a fictional captain on the high seas who wonders why his boat floats and his treasure sinks.

Besides the sea, on Mr Peffer's place, there lived a cow, a donkey, a sheep, a pig, and a tiny little mouse. One warm sunny morning for no particular reason, they decided to go for a row in the bay . . .

Two pocket-size pets meet and get into a tussle when Pug insists that Pig is a pudgy pug, and again when Pig calls Pug a muddy pig.
