Renewable energy sources are in focus as participants build a wind-powered car using straws, Lifesavers candies, paper, and paperclips, and get their car to the finish line using as few puffs of air as possible.
Hints for use in your library: Do you have a 3D printer and design software? You can make your own reusable wheels instead of using Life Savers!
Participants design processes to treat wtare contaminated with acid, oil, and other pollutants.
Hints for use in your library: Use a large, shallow plastic bin to recreate an oil spill in the ocean. Participants can engineer booms and skimmers out of common items to isolate and clean the spill. Assign dollar amounts to each resource. Give the participants a budget that forces them to make choices as they can’t afford “the best” for both oil and acid removal.
Participants build 3-D models of watersheds and experiment to see how human and natural activities affect them.
Hints for use in your library: Connect several model watersheds together to make a larger area. Or, create a dam or use Lego pieces to build houses. What would happen in a flood?
