Science camp (AKA Eco Kids) at the Sebastopol Center for the Arts featured solar oven building (https://solarschoolhouse.org/solarcooking/). We had a competition like this: https://www.bravotv.com/the-daily-dish/jose-andres-top-chef-solar-power-clean-cookstoves The camp was a chance for me to try out some lessons I’m planning for 6th grade science at Orchard View in the fall.
We designed and built fog catchers similar to these: https://www.youtube.com/watch?v=G4GHGBov15U&list=PL6-8azVpUKW4TJG-pbf7Wl9HIqajRCiwk&index=4
