Our cardboard game’s biggest obstacle in the making was the mechanism in which the ball rolls out when it is thrown into a hole. It was hard because the ball kept getting stuck the duct tape keeping the mechanism together, and it often got stuck in the “funnel.”
One thing I will want to change is to not add that mechanism at all because it took like 2 and a half classes and in the end, we didn’t get a chance to use it at all because it broke in the middle of the class during the time when the grade 4’s came to the design center to play our games.
I think overall this product was successful because in the end, we just removed the ball from the game and gave it to the grade 4’s manually and it still worked. The unsuccessful part of the project was that the top of the project fell from the top of the place where we normally put our projects and it caused many problems. The other unsuccessful part was the mechanism.
Some pictures of the project:
I was at a soccer match. The score was 5-5, and there were only five minutes left before the game ended. Air rushed past me as I ran forwards, But I knew I couldn’t score. The other team’s defence is like a huge shield blocking the net. I glanced around and saw my teammate was being swarmed by the other team. I shouted out for him to pass to me, but he wasn’t the type of person who passes the ball. The other team managed to take the ball away from him and started to run to our net.
Panic began to coil in my chest as I settled into a mad dash to the ball. I was running with panic, but also determination. I was faster than the guy with the ball, but he had an advantage. He was getting closer to the net as I came closer to him.
Four meters, I thought. I was gaining on him, but he was extremely close to the net. Right as when he was settling into the position to kick the ball, I ran forward and smoothly, gracefully kicked it out of his way right as he kicked into the air. The expression on his face was so funny! It was the expression of confusion mixed with surprise. I turned the ball around and started to run towards the other team’s net. I glanced forward. Three people were heading towards me. I glance back. one person. I glanced right. Two people. I glanced left. Two people.
It was at that moment when I realized I was completely surrounded. Uh oh. I thought. I ran forward, even though the other team was heading towards me ahead. It was all I could really do, since if I stopped the people behind me will catch up. Wait, hold on. I thought. On the left, there was a hole. Large enough for me to run through, but risky. I decided to take the chance since there were no other possibilities for me to run past them without losing the ball. I was still running forward, because if I started to run that way they would move over and block that passage. As we were getting closer and closer, I suddenly turn and started to run to the left. I ran as fast as I could, and when I looked back, they were far behind me. Good, I thought. No other people were blocking my way now except for the defenders. As I got closer and closer to victory, I kicked the ball with all of the energy I had left. The ball sailed high, like an arc above the defenders and into the net with a swish.
That day I learnt a lesson. If you wanted to achieve something that seemed almost impossible, you can achieve it by being determined and being persistent about it. Whenever I do something that seems to be impossible, I reflect back to that day, when I first scored a goal for my soccer team.
I think the problem we were trying to solve making the outer cardboard layer because since the cup insulator had so many layers the cardboard would be too short to go around the entire thing, which will leave a lot of areas exposed. I had to guess a few centimetres to try to make it fit, and I really only had one shot at getting it right because of the lack of time I had. I solved the problem by a bit because I made some calculations and added around 2cm to the layer and it managed to cover it slightly more, but they’re still was an exposed part. The hardest thing about this was the way to get the cup out of the insulator, and we were supposed to have a mechanism to get the cup out, but we lacked the time and could not do that, so we just used rubber bands to hold it in place. Some skills I’ve learned inside this project was the design cycle since at the start of the project I thought that we would just write a paragraph or sentence of our plane and just start to build the main model, but I never knew that we would have to build prototypes and other things, too. My CER is that the lid of an insulator impacts the cup the most, possibly even more than the sides. My evidence for this was that we didn’t have a lid, and our last temperature log was 72.6. Another group was sitting close to us, so we decided to ask them their last temperature log, and it was around 76 degrees. Their insulator only had one layer of EVA foam, and that was around it, but they had a lid. My reasoning is that a well-made lid will trap the evaporated heat inside, while one without a lid will let it roam free.
One thing that I am proud of is that our insulator worked well because if you were to hold the cardboard you cannot feel any heat coming out of there. One thing I will do differently next time is to add a lid and make the layers smaller so we would have more time to work on the lid and make it look better. The limitations we had was the mechanism to get the mug out of the insulator because it was very complicated and took too much time. We also couldn’t add a lid, and a part of the mug was still exposed.
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
