I managed to be on the Clear Spring School campus in time to observe a bit of what high school science teacher Pete Golden calls science on a shoestring. He and his chemistry class have been on a mission to melt lithium to form an ingot. It is a challenge because it burns in the presence of water vapor, or oxygen. In the photo below, they used a burning candle to remove oxygen from the air, and used a desiccant pack to remove water vapor from the jar. The magnifying glass is being used to focus the suns rays directly on the lithium film inside the aluminum lined crucible. While the experiment did not lead to successful results, it leads to enthusiastic successful learning. It is all part of what we do at Clear Spring School. Hands-on, hearts engaged is not just for the wood shop. Make, fix and create.
