During week 9 and 11 students from Na17 at Staffangymnasiet in Söderhamn were given a wet assignment. They would study their own showering and calculate how much energy it takes to warm up their shower water for a whole year. Then they would approximate how much it corresponds to the school’s 1000 students and how much they should be able to save by showering shorter and more rarely.
The first part of the task was individual. But the generalization to the whole school they did in a larger group to be able to get a reasonable average to work with. Right now, the students are writing a short report as an account of the task.
In the photograph, you can see the group cooperate to get a good average value.
