Can you make a s'more using only the power of the sun?
Can you make a s'more using only the power of the sun? ScienceU campers make pizza box solar ovens that can harness the sun's energy to make a s'more (melted chocolate and marshmallow between two graham crackers). The oven's thermodynamic design uses direct sunlight, reflected sunlight, absorbed sunlight, and insulation to convert light energy into enough heat energy to cook a s'more!

Well, we've got all the fixings for s'mores!
We've got graham crackers, chocolate - marshmallows - but no campfire!
We're not supposed to play with matches...
But all the power we need is right there in the sky!
The sun!
The sun is a big nuclear fusion reactor constantly sending energy in the form of solar radiation to the Earth.
The trick is to harness that energy to make a s'more!
Today each camper will be making their own solar oven using the materials you see here: a pizza box, aluminum foil, sheets of clear plastic and black paper.
First, find an adult - Tell them to cut a three-sided flap on the top of the box.
Spread glue on the inside of the flap and cover it with aluminum foil to reflect the sun's rays into the box.
Lay black paper in the bottom to absorb the light.
Then tape layers of clear plastic wrap across the opening we cut in the lid.
Time to start cooking!
Campers aim your ovens at the sun!
The sunlight hits the aluminum foil - which redirects it through the plastic window - allowing both direct and reflected sunlight into the box - where it converts the light energy into heat energy!
Hot enough to melt marshmallow and chocolate!
Mmmm...
