One Day in the Alpine Tundra by Jean Craighead George*

Johnny is camping in the Alpine Tundra.  A monolith is precarious, about to drop. Various animals scurry about, finding viable plant life.
In short chapters, Ms. George describes this habitat in detail from the animal life to plant life to smaller communities within it.
Very descriptive language and lots of scientific vocabulary.
*Highly recommend.
My mother in law, a fourth grade teacher, used this series to begin her ecosystems unit.

One will learn a lot about various habitats by reading this series "One Day in . . ."
The levels on the back of the book claim the books to be third-fourth grade reading levels.  The Guided Reading levels for all the books are "P"-third grade --which is so incorrect!!
 I agree with the GLE this time!
-Alpine Tundra  (the grade level equivalent is 5.1.)
-Desert (GLE-4.5)
-Tropical Rain Forest (5.5)
-Woods (4.7)
-Prairie (4.9)
