For the past few lessons in science, we have been going to the MS/HS design lab. We have been designing a CUP INSULATOR. We were trying to keep the heat of the water inside the cup, with limited materials and limited amount of time. We also had to mind about the look of the cup (Aesthetics), which made the challenge more difficult. We had to make the cup look good- and we had to ask ourselves this: Is this a product we would buy in a store? Is it reusable? Is it removable? And so on. We also had to decorate the cup in some sort… It was quite a challenge. This is a picture of my partner (Miranda Poh) And me working:
The main problem that we were really facing was the lid. The lid was especially challenging because we couldn’t exactly cap it. we had to find a way to adjust it, and not make it fall off. We did find a solution to use rubber bands and some buttons but when we did the actual test, the hot glue we used to stick them started to melt. (But technically the only item we could use was hot glue and nothing else due to the limited materials) The solution didn’t quite work out. Since Mr Pray but a lot of water in the mug, the water overflowed when we cap the lid. The fabric-made lid started to absorb the water. CER: C-Something I learned is that the thicker the materials are, the less heat loss there is. When we left the mug without the lid by accident, the temp. fell majorly in seconds! I felt that the lid was helping the heat loss a lot. E- The evidence is that when we kept the lid closed, the temp. was flat with no change. And when the lid was off, the temp fell very very quickly. This is an evidence:
(The flat part of the graph is the park where temp was equal)
R- I think why the hot glue happened was because hot glue is melted with a lot of heat. and when the fabric lid was soaked, the button we stuck was slowly melting and it just fell off. The heat affects the glue stick in the glue gun melt, and so does the hot water. I was proud of my work because me and my partner worked actively, and we did not waste any materials. We managed our time, and we finished our project. We worked hard. Something we would do differently is the glueing. I think that because when we put the insulator, the glue we used for the mug started to melt a lot. I would use a differently source of gluing material. But in this case, hot glue was the only option.. 🙁 The hardest thing of this project was the time management. It was hard to do a lot of work is a short time period. This is some pictures of my final cup:

Hi, everyone, welcome to my blog post. For the past few design classes, we have been creating a arcade game using cardboard and other materials. Designing was really unique and fun, and our creativity developed majorly through this. My partner and I (Who is Miranda Poh) decided to make a Pinball Machine. The pictures will be below:
These are some example pictures of my pinball machine. (In case you don’t know what a pinball machine is, it is a game which has 2 flippers, and you have a marble. you press them at the right timing, and try to see how long you can keep the marble with our dropping it down into the hole)
My reflection on my project:
My biggest challenge was to make the obstacles, because they couldn’t spin pretty well. We had to find solutions, but we figured that it was fine. But when the 4th graders came to try out our game, and we realized that the obstacles kept on making the marble get stuck. Another challenge was cutting the cardboard neatly; it was very hard. But after Mr. Gaby (Design TA) taught us that we can use a different type of solution to cut cardboard neater, the solution was solved. We could dot the lines that we needed to cut and then when we cut over it three times or four times, the cut was nice and neat.
Our biggest success was organizing our cardboard parts and having the right measurements. Thanks to our creative Miranda, she had the right measurements for our bits.
Overall, I think that our project was majorly successful because I think we put a lot of hard word into our project and we sewed everything together and it was very good. Our decoration was also very cool; a lot of people enjoyed it. Many people were curious of how me made the flippers move (But its a secret :))
We had so much fun. I am so happy with what we worked out. Thank you Miranda! Thanks Mr, Layman. Thanks reader for reading my post.
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
