Booklist Review - How Do Animals Help Make Soil?

Dirty is the perfect name for a series that will have kids wanting to head outside and see
some of the interesting points the books make about soil—what it is, how it’s formed, what it’s good for.
How Do Animals Help Make Soil? looks at the way creatures, from earthworms to sheep, add nutrients to
the soil; the work of decomposers such as dung beetles and microbes is shown as well. The books are
neatly laid out, with simple text captioning the many color photographs. A good gambit is used to get kids
to turn pages: each spread ends with a question. All of the books end with a science-lab feature that offers
simple experiments for budding scientists. Full of useful information, this series makes the most ordinary
of substances fascinating.
