Australia (and Antartica, too): Week 5 (July 28-August 1) This week campers are going down under (and then way down under). The Great Barrier Reef is home to over 9,000 known species, including clownfish and regal blue tangs. Campers will make a diorama of Nemo and Dory’s magnificent underwater home. To celebrate aboriginal culture, campers will craft boomerangs, didgeridoos, and dot paintings. We’ll make a quick stop in Antarctica this week to conduct simple ice cube insulation tests and learn how penguins and seals stay warm.
