Appropriate for Grades K-4 With this kit, reading instruction flows into science exploration as readily as water moving downstream. While older or more advanced readers will enjoy reading about a set of raccoon twins as they try to solve the mystery of the disappearing pond in Cycles in Nature, younger or less advanced readers access similar factual information in Water. Students explore water cycle processes through a series of hands-on activities developed by teacher Michelle Rose. Introduce or wrap up the topic with that time-tested favorite, Cloudy With a Chance of Meatballs.
