Africa: Week 3 (July 14-18) Africa is the world’s wealthiest continent in terms of natural resources; however, with a huge desert and vast, semi-arid Sahel, access to drinkable water can be a challenge. To help solve the issue of water scarcity, campers will make a water filtration system using sand, gravel, charcoal, and cotton. Because Africa is home to one of the world’s most enduring civilizations, campers will design and build the iconic Egyptian pyramids. Expect kente cloth weaving and Masai necklaces to celebrate some of the people lucky enough to call this rich, diverse continent their home.
