My biggest success was attaching finding a way to attach the cardboard onto a black foam piece. I couldn’t use the hot glue gun because the foam block will melt, so I used tape to stick it on.

The biggest obstacle was trying to bend the wire. When I used the tool to bend the wire, the paint chipped off. It was also really hard to bend the wire the way I like it because it was really hard.

A skill that I learned is being patient with what you are working with because you can’t rush everything. I found it less stressful and easier to work with my cranky contraption after I became more patient and did things slow and steady.

For Save The Penguins, thermal energy trav-eled through the house too fast and not so much was blocked out. Our redesign was worse than our original and lost more than control. I think that the felt and kept the heat in, and it absorbed the heat shining onto it, and then the heat was transferred to the entire building, which caused the ice to melt more.

 

For the Cup insulator, we noticed that the felt absorbed heat, so I considered that maybe the felt would keep the heat in too. we added cotton inside because in the thick winter blankets, cotton is put inside some blankets to keep the heat radiating from your body in, so it keeps you warm, so we added cotton to keep the heat radiating from the cup in. After we were finished, we decorated our Cup insulator with the theme of a unicorn. we then noticed that the cup wasn’t drinkable, so we cut a hole through the top so we can drink with a straw. For our redesign, we added foil in the inside because we saw people getting burned by the foil with hot water or hot glue on it, so if the hot cup was in contact, maybe the foil will turn hot and keep the cup warm too.

 

I am proud of the cup insulator because it did a good job protecting the warmth of the water instead of letting it all out. What i would do differently is the Penguin Project. I wouldn’t have added the felt on top because it absorbed heat, so it lost even more than control. The hardest thing about this project is teamwork when we had to work with our entire table with the Penguin Project.

This project is about making a water purifier to we don’t die of thirst on a deserted island. We had to use materials provided or left behind on the island, for example, a empty plastic bottle, some scraps of clothing, and a few tin cans. We could also use materials like rocks, sand, and dirty water, since we are in a deserted island, there will be sand and rocks surely.

This is a collage with the answers to some questions, and a picture of our final product. I’m glad i won’t have to drink dirty water if i really were stranded on a deserted island! (^_^)
