Are pee and rain similar? Both flow, they take the shape of the container they're in--from a rain gauge to a toilet bowl--and they have a definite volume. That means the water that falls from the sky and some of the waste from the human body are both liquids! In this humorous book, readers learn all about this state of matter, from its features to examples and where the liquid goes after you go! All of the science information supports knowledge building, a key component of the science of reading.
