the purpose of Liam and Colsen's solar over project was to find out how to make a solar pizza box oven more efficient. the first result we got was 29.3 degrees with direct sun for about 20 minutes. Our second trial we had 56.1degrees within 20 minutes that is a jump of 26.8 degrees. the only thing changed to the box was instead of having a black piece of construction paper inside the box with tinfoil around it we switched the paper for a piece of aluminum and kept the tinfoil. our controls were to keep the size of the box the same, the angle of the flap, angle of box towards the sun and color of box. We were very successful in this experiment but I feel like closing all the holes in the box would have trapped the heat in the box and have a more controlled constant heat.
