Lake Life

Introduction to life in a lake

• Picture Book - Pond by Gordon Morrison, ISBN 0-618-10271-X “As winter melts into spring, birds return to the pond, turtles and frogs crawl out of the holes in which they buried themselves during the cold months, and the trees at the water’s edge begin to bud. Witness the array of life in and around a pond throughout the course of a year.”
