BETHESDA, Md. (WUSA) -- The lessons of Science and Social Conscience are front and center at the Stone Ridge School of the Sacred Heart.

Families in third world countries are dying from disease because they cook many of their meals over an open flame and students are learning way they can help. Seniors are designing and building solar ovens.

Lisa Valverde says, "This is 2 cardboard boxes and tin foil, and that's it."

That's right. The foil catches the rays from the sun, reflects into the cardboard box, and in minutes the pot filled with water starts to heat up quickly.

Warm temperatures in places like Uganda help water come to a boil much faster than here in the U.S. so the ovens are successful when it comes to cooking grain. And there are no carbon fumes which can be harmful to your health.

Science Teacher Joanna Caudle says it's also really cost effective. "Anything that you can find that limits the amount of wood or charcoal or food that they have to buy saves them money that they can use elsewhere."

At the end of the year, students are holding a solar oven bake sale and sending the proceeds to their sister school in Uganda! Pretty Cool huh?!
