Solar kitchen

By Alejandro Gil

I perform this activity when the energy theme arrives. It works very well with the groups of the first years of ESO. 

It consists of making a solar kitchen (or solar oven) with recycled materials: one or two cardboard boxes, sheets of newspaper for thermal insulation, some aluminum foil and some plastic film to let the sun's rays go through. 

We dedicate two or three classes to make them and one for them to make a report with the materials used and the steps they have followed. 

Finally we use them! When recess is over they put in a pizza or a sandwich and I prepare some fruit sticks with melted chocolate... delicious!!!
