Description

1996 CBC/NSTA Outstanding Science Trade Book

A pygmy shrew is small—it's among the littlest mammals! A ladybug is even smaller, but it hardly seems tiny when you compare it to a protozoa! And there are many things smaller still—so small that we can see them only with a microscope. Would you believe there are particles that are so tiny that we can't measure their exact size? Explore the huge world of the very small!
