Week 4 of this independent study packet for third graders brings on new challenges in various subjects.

The activities in this workbook do double-duty as both vocabulary practice and earth science review with a collection of word scrambles, crosswords, and quizzes about animals, plants and planets.

Why does the earth spin? How is a rainbow formed? Feed the flame of curiosity in your child, and find out the answers to some of those age-old questions about how the world works.
