Introduce your fourth grader to the concepts of solstices by observing the length of her shadow on the shortest day of the year, compared to other solstices.

Encourage a group of third graders to play this fun game of Whistle Hide-and-Seek as a warm-up to get them prepared for finding a "lost" camper.

Your child helps the environment while saving your family money in this fun and rewarding "Gas Guzzlers" competition.

This activity is a great way to stretch the boundaries of your child's imagination and build up important critical thinking skills.
