Here are some photos that I found.

As many people are aware, the coronavirus has been rapidly spreading causing inconveniences in school, traveling, and much more. My capsule captures links to information about the Virus as well as images to go along. the image on the far left was taken in china and from the amount of protection the doctors are wearing, we can tell how important it is to stay cautious. The image in the middle was taken in Italy. It is evident that there isn’t anyone on the streets apart from one person. And lastly, we have a picture taken in the united states showing the people wearing masks. The coronavirus has had a massive impact on the social power and economy of countries. Many businesses and stocks are decreasing in terms of revenue causing a major economic drop. Furthermore, the government and the WHO have a lot of impacts on social power as well. An example is the travel ban that was implemented on foreigners outside of China. This shows the great extent the government is going to keep people inside the country safe. The WHO also has massive impacts on social power because people look up to them for updates on the virus and trust them as a reliable source for information. A policy that was set in place in many countries was to stay at home and make little to no contact with anyone. This is an important policy because if not followed the consequences could lead to you possibly unknowingly getting affected.

 

 

IDU Final Reflection

During the past few weeks, engaging in the IDU program has taught me a lot about inclusivity, but also the true meanings of collaboration. For collaboration, I would personally score myself at a satisfactory because although I made some useful contributions to the group I still believe that I have room for growth.  For example, when my group and I come together for team time or community time, we would usually discuss our plans and tasks but sometimes I might get a little distracted by peers around. Overall I don’t think our group faced major challenges as we got all our work done on time both individually and together. Some of the Norms we decided on were Be open-minded,  Take responsibility, Compromise, Be present, Everyone contributes And Communicate via WeChat group. All our norms were very straight forward and easy to follow. The only norm I couldn’t follow was “Be present” Because I had to go to Shanghai for a basketball game making it harder for me to stay on the same page as my teammates. But luckily I was updated through Wechat and easily back with the group. Some main challenges of working with a group include disagreements with ideas, not completing work and more.  To solve issues like this, my group and I decided to elect someone to be our ‘manager’ so when things got out of hand, there would be a moderator. In conclusion, I think this unit was extremely beneficial because it taught me how to work well with others but also take responsibility for my own learning.

HOW OUR POLYMER WAS CREATED.

 

Pour 85ml glue into the beaker.

Add 2 drops of food coloring to the glue

Pour 5ml of starch solution to the mixture

Pour in 10.l of corn starch into the beaker with the rest of the ingredients.

Finish with 7 drops of borax

Stir well until the product looks semi-solid semi-liquid

 

Our final prototype was the most successful. Our final prototype did exactly what we wanted, and overall that, it was completely fine when we left it overnight without a package. Our final prototype was also the most successful because we were able to create a certain consistency that was able to support the granulated cylinder. When other groups came over to our table to test out whether or not the object would move, the majority of groups noticed that our polymer was very successful. From our collected data, and peer reviews we know that our last polymer is the best out of all the others.

Something I’ve observed about my polymer is that it could be a little bit sticky. By that, I mean that although it does what its suppose to, little bits of the polymer could get on the cup. This could be a slight problem because then the customers would have to spend more time cleaning the polymer off the cup, as well as clean the cup itself.  But something I also noticed was that we got a really nice consistency by using cornstarch, because for our previous prototypes when using cornstarch, our polymer would turn out really hard, this created a problem because we were looking for something more liquid than a solid. To dodge that, we used completely non-biodegradable ingredients, this led us to rethink because non-biodegradable ingredients are obviously not sustainable. Therefore, when we made our final product out of cornstarch, we were really proud and surprised.  A definite weakness for our group is that we don’t 100% know if our polymer is reusable and or ok to be washed with water. This is important because in order to save packaging material, and money, we need to make sure people can reuse our polymer.

The main physical property I want my polymer to have is color. This might sound like a really vague physical property, but I’ve noticed that more customers are more interested in your product, if you have a variety of colors and types. For the time being, our group has 2 main colors which are green and pink. I definitely think that color will make a really big difference. Now that we have completed our “mock” product pitch, I definitely noticed some areas where we have to greatly improve. Away we can develop our polymer is by trying different materials. If you look at our ingredients list, you can see that we used corn starch, but we also used glue. And the ratio between the glue and the cornstarch don’t balance out. So I definitely think that trying to use different materials that are more environmentally friendly/ biodegradable could really make a difference. A couple methods to test the effectiveness of the polymer could be leaving it out overnight, or even washing the polymer with water. Since we don’t know how the polymer would react with water, it would really be helpful to test it out by rinsing it with water.

For our group, the second class was mainly based on making different prototypes for our cupholder. We experimented using different materials such as corn starch, PVA, and more. We also experimented using amounts of borax. My group and I found that the more borax, the more the polymer solidifies, but we also found that our polymer was more successful when we carefully measured out all the ingredients we used. Our main target/specific goal for this project is to create a polymer that can be used as a holder. For example, you pour a glass of milk and you leave the cup on the table, but accidentally you knock the glass of milk over. With our all new and original polymer, you will not have to worry about tipping over your drink again, because the polymer is easily removable, yet so easy to use. Our main target audience is everyone! From babies to grown adults. Here are images of the potential prototypes we could use. Each prototype has different ingredients used in it, and different consistency’s to it.

Science Blog Post on polymers!

By: Bessy Belay

Polymers are all around us, whether we like it or not! A polymer is a large chain molecule made up of repeated patterns of monomers。The Greek Prefix for “Poly” means many, and the suffix means “Parts”. In 1920, a German chemist that goes by the name Hermann Staudinger proposed the idea of polymers.

There are many different types of polymers, for example, “Biopolymer” or “Natural Polymer”, Synthetic polymer, thermoset plastics, or Thermoplastic polymers. There are major differences between the polymer’s listed above. For example, when we talk about natural polymer, some of the different types of polymers could be Silk, Wool, Amber, Keratin, DNA, Starch, etc.. But when it comes to synthetic polymers, some examples are Polystyrene, Synthetic rubber, silicone, etc… Synthetic Polymers are polymers that are prepared by a chemical reaction.

The process of creating synthetic polymers by combining many small monomer molecules into chains held together by covalent bonds is called polymerization! Polymerization can be split into 2 categories, Step-growth polymerization, and Chain-growth polymerization. The main difference between these two is that in a chain-growth polymerization process, monomer molecules are added to the chain one molecule at a time, whereas in step-growth polymerization, the monomers are bonded directly with one another.

If we take a closer look at the reactions happening while making the slime, The polyvinyl alcohol (PVA) can be made into slime by adding borax solution. This creates crosslinks between polymer chains. The more we add the borax solution onto the PVA, there will be more crosslinked molecules. The larger the polymeric material is made from the reaction. Causing the slime to become more solid.

我的春天故事

春天

我觉得春天很美丽,因为阳光特别明亮,温度不热也不冷,有很多花会开。

在一个农民家附近有一个草地,那个农民看到草地以后,觉得已经春天了,但是草地上一朵花都没长。所以他跑到他家里去找花籽。拿到了以后,他赶快跑到草地上来种花籽. 那个 农民特别努力,他种完的时候已经到晚上十点半了。
第二天早上他去草地的时候,他什么都看不到,他问他自己“我昨天种的花籽怎么突然不见了呢?” 他突然听到声音,望上看的时候看到一大堆鸟在飞。难道是那些鸟吃了他种的花籽。那个 农民特别伤心的回家了,他昨天特别累,但是今天发现没用了。
几个星期以后,农民走出来以后看到一朵美美的红花,他跑到花旁边对自己说“哇啊好美丽呀!”

Once there was a farmer, there was this grassland by his compound, and when he looked at it, he imagined flowers growing on it, so that day he went home, and got seeds, starting to plant it. He was up all night planting and in the morning he realized the seeds were completely gone. Looking up he could see birds flying on top of him, he came to the conclusion that it was the birds that ate the seeds. A couple of weeks later, the farmer saw a red flower, he went up to it and said: “How magnificent”.
