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. The question involved is "How can I design and build a shelter that reduces heat transfer and keeps my ice cube penguin from melting.]]> 2018-02-12 16:55:12 UTC https://padlet.com/willsean/2xzlrzzu8tyu/wish/230694987 willsean https://padlet.com/willsean/2xzlrzzu8tyu/wish/230695273 The three best insulators that we found were mylar, popsicle sticks, and aluminum / black paper.]]> 2018-02-12 16:55:39 UTC https://padlet.com/willsean/2xzlrzzu8tyu/wish/230695273 willsean https://padlet.com/willsean/2xzlrzzu8tyu/wish/230695573 We tested on two different trays, one was plastic and one was metal, and found out that the heat transfers from your hand to the tray faster. The spoons demo displayed that one spoons made the ice cube melt faster. During the black and mylar roof demo, the mylar deflected the light better than the black paper. Lastly, the attic demo displayed that the attic heated faster than the floor. This supported how I was going to make the penguin home.]]> 2018-02-12 16:56:03 UTC https://padlet.com/willsean/2xzlrzzu8tyu/wish/230695573 willsean https://padlet.com/willsean/2xzlrzzu8tyu/wish/230695853 We went with a design that reflected the light from any position in the box and prevented the  heat from entering into it. We used mylar, wooden sticks, and white paper. The mylar would be the roof, the paper would be under it, and the floor would be the wooden sticks.

A failure was that there wasn't any insulators. The percent lost was 35%]]> 2018-02-12 16:57:32 UTC https://padlet.com/willsean/2xzlrzzu8tyu/wish/230696584 willsean https://padlet.com/willsean/2xzlrzzu8tyu/wish/230697535 The successes in the design are that the mylar and cotton balls served their purpose. The mylar reflected radiation and the cotton balls served as an insulator. Our failures are that the cotton balls absorbed it and the paper conducted it easily. The percentage lost was 29.3%. We would add more mylar to support it later on.]]> 2018-02-12 16:58:58 UTC https://padlet.com/willsean/2xzlrzzu8tyu/wish/230697535 willsean https://padlet.com/willsean/2xzlrzzu8tyu/wish/234773809 We added some cotton balls to support and prevent it from melting. It worked as an insulator in the home. The old home didn't have an insulator so that's why.]]> 2018-02-23 16:33:24 UTC https://padlet.com/willsean/2xzlrzzu8tyu/wish/234773809
