The first trial that we did our first penguin lose more than 30%. Then we thought about what we can do to make the house better then we added some more stuff to the house to make it better then the last trial our penguin lost 28%.

We added more lays of Mylar and foil to the top of the roof to keep the heat out of the house

Like all things we had some successes and some failures. Our success was that we had a roof an walls and they were strong and kept some of the heat out. our failure was that the penguins lost 35% instead of 30%

For our design we used Mylar and Aluminium foil we used the foil for the wall then we used the Mylar for the roof.

The Metal  tray felt colder because its an conductor and it took the heat from my hand.
The metal spoon melted the  ice faster than the plastic because the heat that was from my hand transferred to the metal spoon faster make the ice melt faster.
The mylar kept the heat out because it was not black and it makes the ¨sunlight¨ reflect off the roof.
The first floor was colder than the attic because the attic was closer to the ¨sunlight¨.

These penguins need saving. The global warming is causing penguins in South Africa to overheat. when they go into the water to cool off, birds are stealing their eggs so we need to build a shelter to keep them cool so they can stay with their eggs. Our penguin weighted 7.3 grams and was 5.4 grams and it lost 35%
