For me, this project has been one of the highlights of the year! The idea was sparked when I knocked back talk of cooking s’mores on a bonfire at camp. Being close to summer (and a stressful situation for the adults) we had decided to forgo the bonfire option at Narnu. So I posed the question “how can we cook s’mores without a fire?”. From here we learnt all about heat transfer; conduction, convection and radiation, and applied this to making a solar oven that would maximise the heat from the sun to cook s’mores. The students went through many phases of designing and modifying their solar ovens, and by the time it came to making the oven, everyone had a really clear vision of what their solar oven would look like. While we didn’t get to use the oven at camp, it was a great success and deliciously fun. Here are some photos!
