Background Information:
 Solar Oven’s provide an easy way to
save electricity. It has to be hot out to
cook something, the sides of the cooker
reflect the heat to the middle of the
cooker. It works by collecting heat from
the sun and concentrating it to heat a
pot or other container for cooking. Solar
oven feature some kind of reflector to
gather and concentrate the sun’s ray’s.
You can cook things in a cardboard box,
Styrofoam, and metal and cooker’s.

Testable question
Does a aluminum foil solar oven
cook faster then a black garbage
bag solar oven?
Hypothesis
If you cook food on aluminum foil
then it will cook faster then a black
garbage bag.
Experimental variables
Aluminum foil
Black garbage bag
Control variables
Cookies
Cardboard
Materials
 Card board box cut
in half ( 2 ft. and 1
inch each )
 1 tablespoon of
Cookie dough
 Aluminum foil ( 1 ft.
and 3 inches )
 Black garbage bag
(1 bag )
 Paper and pens (to
take notes.)
Procedure
A
I buy all my material’s
B
I cut the cardboard box into a rectangle shape
and tape on the garbage bag onto the
cardboard box. Repeat for the foil!
C
Then make the cookie batter and put a spoonful
of batter on both, foil and garbage bag solar
oven.
D
Then I make cookie batter & put a spoonful of
batter on the solar oven.
E
Then wait and take notes and time the cookies
and see which one cooks faster repeat x2.

Data Analysis



In my project tin foil was faster, but they
both cooked the cookie the same way
from the bottom to the top.
It seems that they both cook the same
way but the tin foil seems to cook faster.
Something unusual that I observed was
that the cookies grew in different shapes
the garbage bag grew up, and the
aluminum foil grew flat and crisp!
Conclusion
 My hypothesis was right, the
aluminum foil solar oven worked
faster!
 I know that it is right because the foil
attracts heat and the heat reflects to
each side of the foil which makes it
heat up faster and cook better.
 The garbage bag did not work as well
because the bag was plastic and it
melted a little bit, which ruined the
cookie and it cooked slower because
it did not attract as much heat.
