WeCoExist Turns a Classroom Bin Into a Waste-Reduction Quest

Field notes

The project combines a physical ultrasonic sensor with a classroom data workflow: readings move to the cloud, then appear as class-bin graphs, school averages, and longer-term trends. The homepage also provides teacher-oriented material, including a quick-start guide, three investigations, resource links, and curriculum links. Its stated audience is Year 5–6 education, and the site says the system uses no student data. A robot character is presented as a guide that encourages, celebrates, and interprets changes in the readings.
