What We did for the Hot Can
For
the hot can we covered
the can with layered paper
towels and set it up as close
to the celling as we could
near a light. This setup uses
convection, conduction, and
radiation.
What we did for the Cold can
 For
the cold can we put it on the
ground and put a layer of cold paper
towels over the cold can which we
changed twice before deciding not to
do it anymore because it was actually
making it warmer. This setup uses
convection and conduction.
What we could have done Different
 To
improve our experiment we could
have put the cold can outside and
for the hot can we could have
wrapped the can with tin foil instead
of paper towel because the paper
towel got wet and cooled the can

Hot, Cold, and Controlled
 The
hot can lost a total of 9.8 degrees C.
The cold can only lost 8.8 degrees C.
Comparing them to the controlled can which
dropped 5.3 degrees C, our hot can lost 3.5
degrees C more and our cold can lost 4.5
degrees C more. This shows that our experiment
failed for both the hot and cold cans.
Real life Example
 Just
like for the hot can, in a house the
basement is usually cooler than the attic
due to convection.
 As
with the cold can if you were wearing
a wet jacket it will cause you to become
colder.
