Today we had a challenge to see if who could keep their ice cube from melting the longest. For supplies we had tin foil, paper towels, copy paper, a toilet paper roll, and a plastic container to put the ice cube in.
When we were designing our box we had to problem solve. We had to practice team work and not have one person do all of the work and how to have good sportsmanship.
Team Beast Boys layered the supplies in a pattern and over cut the materials so we could fit all of our tiny pieces in. We decided to layer the materials because we thought that would make a good insulator. We decided to put half of the supplies out so we could put the ice cube in, then we put more of the layers on top of the ice cube. If we get to do this again, we will cut the TP roll in half and make two pieces then put the cap on. Under the TP roll, we’ll put paper to insulate our box. We’ll still have good sportsmanship! We will also be humble!
Team Film Theory’s strategy was to put the foil on the bottom then wrapped the paper towel piece under the foil so the foil wouldn’t get wet, the paper towel would so the container wouldn’t leak. Then we put the roll inside of the container so it would soak up melted water. The biggest challenge was building the container. The easiest thing for us was putting the tin foil in the bottom.
Team Georgia’s strategy was to put the tin on top to reflect the light then put the TP roll aroundnd the ice cube to support the tin foil and protect the ice cube. Our weakness was that we didn’t layer the insulators and we left a couple holes. We kind of good and bad with our design, next time we’ll put more layers.
Team USA said it was difficult to pick a strategy to build because there were conflicting ideas
between group members. After that, we decided together on what to do. The easiest thing to do was to put it all together inside the box. We decided to put the tin foil on the bottom and then put paper towels on top of the foil and a paper towel on the lid and the TP roll in the middle to put the ice in there. Next time, we would put the paper towels on the bottom instead of the tin foil to help reflect the light. I would put the paper towels around the box.
Team Uni’s strategy was to put paper on the bottom and layered our items. We kept layering the paper and napkin and the tin foil on the top. Then we put the ice in the napkin. We thought that would insulate our ice cube. Building the box went well. A challenge for us was figuring out how to build the box. We ended up working together.
Team Mystic put the foil on the top of the box and lined the sides with paper then we put a bunch of strips of the TP roll inside and then put the ice cubes in and placed a paper towel over it. We worked well together with coming up with our idea. The biggest challenge was deciding whether to put the paper on the sides or not.
Team Girls’ strategy was to trim the tin foil to fit perfectly and block the holes. We layered two layers of the paper towel then we put it on the lid. Our biggest challenge was the time limit. The thing we did the best was putting all of the pieces together. Next time we would add more layers so it wouldn’t leak as much.
Lastly, Team Pizza Party pulled out the LONGEST time for their ice cubes not melting. After one hour and 19 minutes, their container still had SOLID ice in it! Their cube did melt a little, but was very greatly insulated! They used a strategy of layering their materials all around the ice cube as to have a very tight seal. Coming up with a name was a challenge, but they were very happy with the outcome.
So, what did we learn?
That layering materials is a good strategy to keep the ice from melting and that conductors and insulators working together can make a great ice box! We had a great time working together!
