For Save The Penguins, thermal energy trav-eled through the house too fast and not so much was blocked out. Our redesign was worse than our original and lost more than control. I think that the felt and kept the heat in, and it absorbed the heat shining onto it, and then the heat was transferred to the entire building, which caused the ice to melt more.

 

For the Cup insulator, we noticed that the felt absorbed heat, so I considered that maybe the felt would keep the heat in too. we added cotton inside because in the thick winter blankets, cotton is put inside some blankets to keep the heat radiating from your body in, so it keeps you warm, so we added cotton to keep the heat radiating from the cup in. After we were finished, we decorated our Cup insulator with the theme of a unicorn. we then noticed that the cup wasn’t drinkable, so we cut a hole through the top so we can drink with a straw. For our redesign, we added foil in the inside because we saw people getting burned by the foil with hot water or hot glue on it, so if the hot cup was in contact, maybe the foil will turn hot and keep the cup warm too.

 

I am proud of the cup insulator because it did a good job protecting the warmth of the water instead of letting it all out. What i would do differently is the Penguin Project. I wouldn’t have added the felt on top because it absorbed heat, so it lost even more than control. The hardest thing about this project is teamwork when we had to work with our entire table with the Penguin Project.
