Solar Cooking for a Developing Nation
Background: Solar energy is the least polluting and most inexhaustible of all known energy sources, and it is free.
Cooking in a solar oven is easy, fun, and helps the environment. Many Americans are aware of the need to take
responsibility for the greenhouse gas emissions we create. Carbon dioxide released from burning fossil fuels like
oil, coal, and gas is harmful to the environment, and is created when using electricity or gas to cook your food.
Using a solar oven can be an important step towards your family becoming “carbon neutral”, and for some families it
is a necessity for cooking food and pasteurizing water. People from all over the world depend on solar ovens. The
Peace Corp has provided a grant to fund the research and construction of solar cookers to be used in third world
countries where there is no electricity for food preparation. You have been divided into design teams to complete a
prototype cooker for testing and evaluation.
Framing question: Why would your solar oven be useful in the developing country of your choice?
Four questions about your developing country:

2. Research a solar oven design (GROUP)
a. Must be made from common household equipment (cannot be purchased)
3. Decide on the food item that will be cooked (GROUP)

4. Build a solar oven (INDIVIDUAL)
a. You must have proof! Pictures are great but you could bring it in too.)
5. Redesign your solar oven to work more efficiently (GROUP/ INDIVIDUAL)
10/14
6. Write a research paper which includes (INDIVIDUAL):
a. description of the country you chose to make the solar oven for and why
they need it (four questions and answers defending your argument for the
framing question). You need facts!
b. the science behind how a solar oven works: how energy was transformed
from one type of energy to another, the change of matter that occurred
(physical and/or chemical) (and how you knew), changes in state of matter (if
applicable, but this needs to be discussed), whether the thermal energy was
endothermic or exothermic (and how you knew)
c. how your specific solar oven worked: was it able to cook the food (how did
you know), did the redesign work, (how did you know), did yours work better
or worse than your group members (why do you think)
7. Presentation of your groups solar oven (GROUP)
a. At least one solar oven must be brought it
b. Students should have pictures that show the country of your choice
