To make our padlet better we added more material on the door, added more tape and other material´s inside. We did this to use more insulation and have more protection from the heat so the ice wouldn't  melt. The redesigning was not a success. We did worse than the prototype. We had a 54% loss. We did good at having a lot of materials to protect the design. We should have used different materials for the design to make it better.

We use mylar, construction paper, bubble rap, felt, and feathers. We built insulators on the top to stop heat. Overall our prototype was a decent start. It had a starting mass of 7.6 and a final mass of 3.5. The percent loss was 54%. I thought our prototype was a success but I would like to do better for the final. A success in our design was we had a lot of protection from the sides. A failure was we don't have enough protection on the inside.

We are testing materials to find good source to build the penguin shelter. The best insulators were mylar, white felt, and aluminum. I will make sure to use good material on my house. I learned a lot about insulators. I will probably use a good insulator to build my home such as mylar or aluminum. That way the penguins can stay cool in the shelter. I will probably use mylar for my roof and aluminum on the sides.

The Boulder Beach penguins live on the coast of South Africa. They are an endangered species. They need saving because seagulls are taking their eggs and they are overheating. I learned in the tray demo that even though conductors and insulators can be the same temperature,  conductors feel colder because of the heat transfer between your hand and the metal tray. I learned in the spoon demo that things melt faster if they are on a conductor because of the heat transfer. In he house demo I learned that insulators also repel radiation.
