Ask classmates to share their ideas and knowledge. “Do you know if plastic spoons are recyclable? I’m always so confused about how to sort trash . . . There are so many bins!” “I know, climate change is really scary. The news lately has me so freaked out. Do you think there’s anything we can do?” Remind classmates about energy-saving habits in a friendly way. “I’m gonna head home now . . . Would you mind flicking the lights off on your way out?” “Hang on one second, I’m just going to close that door -- apparently it helps save energy.” Share your own efforts to save energy. “I just went and talked to Ms. Ashton about switching to better lightbulbs -- I read somewhere that the new ones are way better for the environment -- and she was really nice about it! She said they’re expensive but she’ll think about it.” “Ever since that Earth Day presentation, I’ve turned into an energy vigilante . . . I’ve been trailing my sister around the house for days flicking off all the lights she turns on, haha.” Invite classmates to work together. “I think people are just confused about how to sort their trash. The way it’s set up now doesn’t really make sense. I might make some flyers this weekend to explain it more clearly . . . Want to come over and help? “I know it’s not the most exciting thing, but I really think it would be awesome if the school switched to more energy-efficient windows. It’s better for the environment AND we’d save a ton of money on heating. I’m going to talk to Mr. Wu about it on Monday. No pressure, but if you came with me, I bet it would be more convincing. We need your debating skills!”
