Explain the problem you were trying to solve​:

Penguins get hot in the extreme weather and take a swim in the ocean. While swimming, they leave their eggs unguarded, giving their predators a chance to hunt down and eat the eggs.

 

 

 

Explain the reason for your design and redesign.

 

We made our penguin design out of mylar and white Felt constructing it into a dome like shape. We used mylar for the roof and the sides because when we did our data test, it only lost 3.5 (C) degrees in 3 minutes. Mylar is a form of polyester resin used to make heat– resistant plastic films and sheets. We used White Felt for a double-layer of rood and also the floor of the dome. We chose felt because it’s made of fiber and when we did our data test it only lost 4 (C) degrees in 3 minutes. Felt is a kind of cloth made out of wool, ice melts slower on felt and the color white reflects heat.  

 

When we did the redesign, we noticed that hot glue melts in the temperature of the box. To solve this problem, we first covered the edges with tape, put hot glue on the tape and then put more tape on. This will guarantee that the hot glue won’t melt, so our design won’t fall apart.

 

 

Write an explanation about which design worked better, using the data you collected as evidence.

 

Our redesign worked better, because the first design lost 10 (C) degrees in 20 minutes, while our redesign only lost 4 ( C ) degrees in 20 minutes. Also, our first design fell apart while our second design stayed intact.

 

 

How has your understanding of the transfer of heat energy and temperature changed during the penguin project?

 

I feel like Convection was always the hardest heat transfer to understand, but while doing the penguin project, from creating the design to finishing the poster, I understood more. I also got to further understand the other different types of heat transfer.
