Would you like to try to create a project that has a 'carbon trigger'? A carbon trigger can be created by calling an API that calculates when the electricity production in your local area is the most 'green' - a great moment to run a dishwasher or a gas dryer. This repo contains instructions for a hackathon and workshop activity for students. There are also 'train-the-trainer' instructions for teachers, coaches, and instructors.
If you're participating in a hackathon, here.
