Solar Oven Investigation

We have been testing solar ovens in science. These are my observations. The question is what oven heats up the fastest. The first oven started at 23.1°c after 3 minutes the temperature was 29.3°c and after 3 minutes of cooling the temperature was 26.0°c. I think it heats up because of the black paper at the bottom of the box. It cooled down because the black paper absorber the heat. The second oven started at 23.6°c after 3 min the temperature was 25.2°c and after 3min of cooling the temperature was 21.5°c. I think that the second oven heated up slower because there was plastic instead of black paper. The way solar ovens are built effect the results.
