The students camped out and learned outdoor skills like edible plant identification and water filtration methods from local guides and teachers from the local vildmarksgymnasiet (wilderness high school)- a type of Swedish school that combines usual academic lessons with practical outdoor skills in hunting, camping, fishing, and backcountry guiding.
Ann and her colleague Anna-Karin from Sydvatten ran a role-play activity on water management, my colleague Torsten Krause led a workshop on conflicts over water in Sweden and California, and I led an exercise on virtual water. We traced the water needed to grow our food, for example showing that a simple margarita (cheese and tomato) pizza requires enough water for more than 20 showers.
I also asked the students to test out and give me feedback on some quizzes and worksheets that my master's student, Seth Wynes, has developed as part of his LUMES thesis on high-impact actions for high school students to reduce their carbon footprint. In the quiz, only one group correctly identified that avoiding flying was a more effective way to reduce their carbon footprint than upgrading light bulbs. (In fact, Seth's research has shown that avoiding one long-haul flight saves more than 10 times more carbon than upgrading light bulbs, and yet the Canadian high school science textbooks he's analyzed suggest light bulbs as a climate solution more than five times as often as they mention air travel). I hope we can incorporate these teaching materials in local high schools here in Sweden, as well as the Canadian schools where Seth is working to implement them.
