"I have no special talent. I am only passionately curious" - Albert Einstein

For my 6th grade design class, my partner, Mika Kamiya, and I created a foosball game made of cardboard. We spent about four classes  on it. 🙂

One skill I learned while making this game was how to handle certain tools in the design lab. For example, I learned how to properly handle a cutting knife. Another skill I improved on was cooperation. Mika and I made this game together, and we had to work hard and split the work among the two of us.

Our biggest obstacle was the measuring part. This is because for the foosball game to work, the figures in the box had to be able to spin. It was really hard to make all of the figures the exact same size. Also, the ball we were using, which was a ping pong ball, had to be able to fit through the goals. The two goals on either side of the box had to be the same size too.

One thing I would like to change is the skewers connecting the figures and making them spin. The skewers are too fragile, and they have broken a couple of times when we were making the game, resulting a huge amount of hot glue. If I were to make this again, I would use a thicker and more sturdy stick instead.

Overall, I think our game was a success. The skewers turned, and the ball fit through the goals. It was like the actual foosball game,. but only a bit smaller.

Cup Insulator!

Problem:

The problem we were trying to solve was to make an insulator to keep the liquid in the mug hot for as long as possible.

Process:

First, we each made a sketch of our ideas to solve the problem. Then, we shared our ideas with each other and took the ideas we thought are good and put them into one sketch, which was the design we made, and created a paper prototype of it. After carefully picking out the material, we made our insulator and tested it out by putting it on a mug, pouring hot water into it, and checking the temperature every 20 seconds. Afterwards, we recorded the start temperature, end temperature, and the decrease temperature on our sheet of paper.

This is a picture of my group working together and sharing our ideas.

Claim, Evidence, & Reasoning:

C- Plastic caps work the best for holding heat in from the top of the mug.

E- With the plastic cap tightly secured on the mug, the temperature of the water decreased by 8.8˚C in 10 minutes, but without, the temperature decreases by 20.9˚C. Also, even though the temperature of the water we started with the insulator was lower than the temperature of the water without the insulator (lower by 5.8˚C), the temperature we ended with the insulator (78.0˚C) was higher than the temperature  we ended without the insulator (71.7˚C).

R- This makes sense because there is no openings in the plastic cap we used, so heat would stay trapped in the mug. Before we settled on using a plastic cap, we thought about using a piece of fabric, but then, we realized that it wasn’t a good idea since it had tiny holes and openings in it, so heat would escape.

This is a picture of our final insulator being tested!

What are you proud of?

I am proud of the fact that my group worked very well together and discussed and shared our ideas with each other to make our insulator work better. We also separated work evenly among the three of us.

What are some limitations your group experienced in this design challenge?

A limitation my group experienced was the fact that the insulator had to not interfere with drinking. This was hard because we could not just cut a hole in our covering because then, heat would escape.

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
