When Miss Fox shows up to school one day on her bicycle rather than in her car, her students are surprised. Is her car broken? No, she tells them, she is "going green." After her students show an interest, Miss Fox explains to them that going green means using less water, energy, and different kinds of stuff. After the kids joke about saving water by not taking showers and saving paper by not doing homework, they get serious and start coming up with some changes they could make, like using heavier blankets instead of turning up the heat or turning off lights when leaving a room. It looks like going green is going to be fun! This upbeat story is a great way to introduce the concept of treading lightly on the earth. It may even inspire kids to go green themselves.
