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.

Earth's neighbors have landed: the planets that is! Your child can make his way across our solar system, planet by planet, learning interesting facts like any good astronaut, and making a 3-D mobile.
