My Cardboard Arcade Creation

I think my cardboard arcade was successful because it work very good when the 4th graders came, and also it was possible to win so it wasn’t unbeatable. I think my cardboard arcade was also a bit not successful because the shooter broke a bit when the 4th graders came and eventually it broke completely at the end of the class, but I still fixed it after. My biggest success was the shooter and the flickers because it worked better than I thought. But my biggest obstacle was when the shooter broke because it was very hard to fix and it took me a lot of time. One concern that I have is that there not a lot time to work on our cardboard arcade, so we didn’t have time to decorate it.

Cup Insulator Design Challenge

Explain the problem you were trying to solve

A. The problem I was trying to solve is to make a cup insulator and make it that it can trap the heat from the water in the mug, so it’s to make a cup that can preserve the heat so the water can stay at the same temperature.

Explain your process for solving this problem. (Write about how you used the engineering and design process)

We first made our individual idea about what materials and what the cup insulator is going to look like and how we are going to make it. Then, we came together and decided on one idea. Next, we made a paper prototype of it. Then, we made the actual prototype. Finally, we tested it and see if it worked.

CER (Claim, Evidence, Reasoning)

Claim: My cup insulator successfully preserved the heat in the mug and worked well.

Evidence: The control group lost 20.9Cº in 10 minutes, and my cup insulator only lost 12.1Cº in 10 minutes, so it was successful because it lost almost half of what has lost in the control group. The water should naturally get colder because when you leave you cup of water out for 10 minutes, the heat will escape in the air and the water will cool down. The cup insulator does the job of trapping the heat in the cup, but the heat will still escape. Compared with the control group, it’s much better and the cup insulator is successful.

Reasoning: The reason why my cup insulator worked is because the cotton balls, thin Styrofoam, and the felt trapped the heat and also, we had a lid, and a bottom, so it was covered completely. The only problem was that the materials weren’t waterproof, so it got wet, in result to that the materials were didn’t work as well.

Did your product work well? Why or why not? Include data to support your statement.

My prototype worked well because the control group lost 20.9Cº, and my prototype made it only lose 12.1Cº. it also worked well because it was removable and convenient.

Respond to at least 2 of the following to complete your blog

– What are you proud of?

I am proud of working in a team with Alex and Miles, and creating a cup insulator that worked well.

– What would you do differently?

I would have made assigned tasks so we could do a lot of things at the same time, so we could have time to improve our prototype. We could have used waterproof materials because the felt and the thin Styrofoam got wet, so it wouldn’t work so well.

– What was the hardest thing about this project?

The hardest thing about this project is working together and use the time efficiently so we could add on to our prototype.

– What are new skills you learned in this project?

I learned that working together is important, especially when there’s a short amount of time and we need to make something.

Welcome to Your New Blog!

When you blog you create posts and posts are categorised according to your subject. Some categories have already been set up for you. If you need more categories you can add them as needed. It’s important that your posts have the following:

  • An engaging title – this should not include the name of the subject since this is referenced in the category.
  • Body – this is where you share your learning. This can include text, images, embedded videos from Dragons’ Tube or elsewhere. You should always consider how your post looks to your audience. Is it engaging? Do they want to keep reading?
  • Category – select one that has been set for you or add a new category. Posts can have more than one category e.g. Humanities and Myself as a Learner
