We love science yes we do-
Kids: We love science yes we do!
We love science, Science-U
Kids: We love science,
Science-U!
When I say science, you say 'U'
Science!
Kids: U!!!
Science!
Kids: U!!!
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... !!!
S'mores!
We love s'mores, yes we do-
Kids: We love s'mores,
yes we do!
We love s'mores on ScienceU-
Kids: We love s'mores
