The Successful Cardboard Arcade Design

The Successful Cardboard Arcade

Why was it successful?

The reason the design is successful is because of its simplicity and fun. It’s a basketball cardboard arcade, with 3 hoops. The catapult is made with popsicle sticks and is easily adjustable to the perfect need. The catapult is very strong, and it can easily let you score. The closest hoop is 50 points, the very back of the hoop is 150 points. With 20 points extra points if you score from the top.

Overall, when 4th Graders tried to play our game they had a lot of fun. Every one of them smiled when they played and scored.  They even told us that they really enjoyed the game and it was a lot of fun.  So I think that this game was pretty successful.

If I did this again, some things I would do differently is:

1. I could cut the cardboard neater, and glue it neater. We didn’t care TOO much about the aesthetics of the game. However, once we put it together it turned out, it wasn’t too good looking. If it was better then more people would definitely have played our game.

2. Improve the hoops. We did square boxes for the hoops, and I wouldn’t really consider them “hoops.” It was more like a floating box that is hollow. It would have been more satisfying if the hoops looked nicer. However, it stilled worked.

3. Decorate the game. The game worked fine, however with more decoration we could have made the game really POP.  We could have drawn the court on the floor of the game, and added NBA stickers on the sides.

If someone was going to do this, what advice would I give them?

Imagination comes is a powerful play in this design. The design is mostly made by skill and imagination. The design is very creative. So use your imagination when you do this. The more imagination you have the better the game will be.

The Heat Insulator Design

The Heat Insulator Design

By Alex Li

The Problem

The problem that we were trying to solve is to find a way to contain heat in the mug. We had to design a design that needed to contain heat for as long as possible.

The Process

As a team, we (Miles, Justin, Alex) had come up with ways to isolate heat in the mug. We brainstorm different ideas and ideas in the past that have been successful. We came up with one design that seemed promising and chose it.
We decided on the materials that we needed to use for this project. Planned out the prototype and model and made it.
At the end of the model, we did our final draft and added all the proper materials and hot glued them. We used different materials such as felt, cotton balls, etc. The model was successful in my opinion, and we only lost around 12 Degrees within 10 mins. To good designers, it would be trash, but to 3 middle school kids, we thought we were quite successful.

The Design

The original ideas were separately thought of, when we finally chose one good idea that seemed to work, I drew the prototype. (As seen in the image below the blog.) We got materials and started working after our paper prototype was finished. The design is many layers of thick felt and a lot of cotton balls. Which we thought it SHOULD contain heat long enough for 10 minutes.

A Claim

The Mug naturally melts 20.9 Degrees within 10 minutes. While our model makes the cup only lose 12.1 Degrees within the first 10 minutes. There is a 7.8 Degree difference.
This happened because there are more things or material covering the mug, making the molecules of heat isolate more because it’s blocked.


We accomplished many things along the way, we accomplished being a team, a design that works well. We all feel proud of ourselves.
