Ok at school we are doing this thing, where we have to make a brochure about energy and present to the grades below us. We are doing a little presentation where people walk up to us and asks us about our topic, and everyone else has props for there presentation apart from me. My topic is on where earth will be in the future, and conserving energy-what happens when you do and don't.

I don't have much time because we are doing it first thing in the morning.

Please help!

Any ideas for props? Like what kind of props would you use for conserving and not conserving energy and where Earth will be in the future?

Thanks in advance!
