Solar Ovens

Tomorrow we are starting to work on our solar ovens. There are 3 ways to heat the s'more: radiation, convection, and conduction. Radiation is heating without touching the heat source. An example would be the sun. The sun can melt ice cream from a distance. Convection is heating with a liquid or a gas. An example would be a convection oven. The hot air rises to bake the food. Conduction is when the heat transfers through the object. An example would be touching a hot element. The heat transfers through your hand.
