I am really proud of Emily C and I’s teamwork skills and how we made our prototype for both the penguin dwelling and the cup insulator. I am astonished that we worked together so nicely that we each had a role to do at all times that we liked and agreed among materials and designs.

I am also astounded by how we made our prototype for both the penguin dwelling and cup design. In the penguin dwelling, my teammates and I all agreed on the materials and design and also, we all had a chance to build and test out the materials. Later, we got a very low decrease in mass on the “penguin” because of a well designed dwelling.

For the cup design, I was surprised that we pretty much had the same idea and a very low decrease of temperature. We used polypropylene sheets (plastic sheets), yarn, thick baize fabric (rough cotton fabric), hot glue, velcro.

The hardest thing about both projects is testing out materials. Usage of “squid” was quite hard. Since squid was money, many materials were quite expensive and planning out wether to buy something or not was quite a difficult choice. This was not the only reason why it was a difficult choice though, it was also a extremely difficult choice because a plan changes every now and then and there was a material that we bought that we turned out not to use and that was a waste of “squid” and we didn’t want to waste “squid” anymore so had to choice wisely.

In the penguin dwelling project, the goal was to make a prototype of a home that a penguin can stay in that reduces thermal energy transfer. We made the penguin dwelling prototype out of aluminium foil and mylar.  In the cup insulator, the goal was to make a prototype that prevents heat lost or basically a cup insulator that allows the liquid inside a mug to stay warm during the winter, on a day to day basis, etc.
