Celebrating Earth Hour

I'm looking forward to celebrating Earth Hour on Saturday night, and so are my kids. For some reason, it's so exciting to sit around in the house with all the lights out and no technology! (My kids have fond memories of the Big Blackout of 2003 when they played hide-and-seek in the dark in a friend's house.)

I've been looking for a picture book about Earth Hour to read to my kindergarten students. So far, I haven't found one that specifically focuses on Earth Hour. If you've come across one, I'd love to know about it. Maybe there's an opportunity for someone to write one, since Earth Hour seems to have become a worldwide tradition!

To celebrate Earth Hour at my house, we usually play a board game by candlelight (and eat snacks). Do you have any great ideas for celebrating Earth Hour?
