Hola! In Science last Thursday we made solar ovens! In groups of 3-4, we got pieces of cardboard, foil, skewers, and tape.
We could shape it however we wanted to. My group covered our whole structure in the foil. Once done, the teacher gave us a biscuit and two marshmallows each to put inside. We went outside and waited. The result took a while to come so we got magnifying glasses to speed up the process.
We used the reflection coming through the magnifying glass to burn the marshmallows.
Have you ever made a solar oven?
