A change that we made was to add a "door". The purpose of this was to keep the heat from just coming in thru the entrance. A successes was that we did better then last time by adding a "door". Something not good is that when the heat did get in it would stay in there. We ended up with a percent loss of 67%.

The prototype is a dome and uses mylar and tinfoil. These materials are both reflective. So the heat will bounce right off. we also put popsicle sticks to keep the structure strong and to make a secant layer so that there would be two layers of materials to fight agenst the heat. After testing we found that our successes were the roof. But we found out that a lot of heat was coming in throw the door. Our percent loss was around 75%.

Today in class we were testing different materials so we can know what materials to use in the project. The best insulator is aluminum. The secant best is mylar. The third best is white paper. I will apply this to my home buy putting aluminum and mylar in my design. I will also layer them for better performance.

The Name of the penguins:
Boulders Beach Penguins

Where do they live:
cost of Africa

4-8 lb,  20'' in  can't fly

Are they endangered:
yes

They need saving because the penguins are getting hot and need to leave the nest. When they do there eggs get eaten.

What I learned from the try, and spoon demos is that metal steels heat from objects. I will use this by not putting my penguin on metal.
