Summer camp themes tend to focus on activities that are best experienced outdoors. Summer is a great time to focus on water play, team sports, field day activities and messy art projects.
Dedicate one week of summer camp to a Field Day/Olympic theme. Invite local athletes or coaches to visit your campers, and plan team-building games such as three-legged races, pass-the-baton relays and egg tosses. At the end of the week, pass out medals and ribbons to all participants. Another popular summer camp theme is messy art projects.Teach campers to make their own play dough on picnic tables outdoors, experiment with food coloring and water balloons, and invite campers to try "splatter" painting their own t-shirts. The messier the better, and campers enjoy bringing their creations home.
