Skylar v’s, Monika’s,
lou’s, Insulator
Our teams first insulator had at the bottom styrofoam to hold it in place.
Then we put two cups together and put tinfoil over it. Then we put the cup
in the styrofoam holder. After that we covered the whole thing in wax paper.
After we put the wax paper on it we put folded tinfoil at the top. We folded
it into a square.
Our insulator worked the best. At the end we had the largest ice cube. At
the first time we checked it it was still a whole ice cube. At the second time
we checked a few drops had melted. At the third time we checked it a little
puddle inside had formed. Finally the end we had showed our ice cube
around. They were thinking between our group and another. Then we got the
answer. Our insulator worked the best.
Our second insulator was almost the same. We still had the styrofoam
bottom. But we had put tinfoil in it so we could put cold water in to keep it
cool. Then we still had the wax paper, and cup. But at the top we put on two
folded pieces of tinfoil instead of one.
We designed it this way because we thought the wax paper would keep it
cool. We also thought that the styrofoam at the bottom would hold it up,
and it would act as an ice pack. We then thought that the tinfoil that a was
around the cup would keep out the heat which would reach the ice cube.
Then we thought that the tinfoil at top would make a good cover to the top
because it was secure. And we thought that the cup would seal well when we
taped it and we found a good way to open and close the cup easily without
interfering with the cube. Then we added tinfoil at the bottom and water at
the bottom over the tinfoil then the next day the tinfoil was very cold and
acted like a ice pack.
Our second insulator worked about the same at 10:40 it was all solid
because that was the beginning. At 11:10 it was still all solid. Then at 12:04
there was the smallest bit of water. At 12:45 it melted a bit more making a
little puddle. Then at 1:15 it melted more and there was a bigger puddle.
We would redesign it with more, A lot more tinfoil and we would add paper
towels, and a cup opening so we can see inside. Then we would keep the
styrofoam at the bottom. So the whole thing would be a tinfoil house
wrapped in paper towels with a styrofoam bottom. We thought it would
work better that way.
Out teams third insulator worked about the same as always just a little, The
smallest bit worst. At 11:45 it was still all solid (because that was only the
beginning.) Then at 12:45 it was still all solid and we thought that that was a
good sign for us. Then at 1:13 there still was a ice cube only a little bit of
water. Then at 1:48 (which was the end) there was still a ice cube only a little
more water than before.
I thought the best insulator was
Dylans group because their
insulator was a tinfoil house and
roof covered in paper towels
nothing else. And when they put
the ice cube in they also had a
drain to take out the water and
then the ice cube was staying large
and was the largest at the end.
