this is my blog, where I’ll post reflections/work I do in CDNIS.
单元反思 Unit Reflection:
- Skill / ATL(语言技能,学习方法)
- Learner Profile / Action (学习者档案,行动)
▪ 我的功课样品 My sample works:
- 这份功课做了什么?What did you do for this work?
I had to first write a speech about being a School Tour Leader and discuss the designs, clubs, and other subjects.Then you had to use photos on the slides and record a audio along with the video.
- 我做得好和不好的地方。 Why did you select this work to share?
I selected this work because it’s one of my best works and shows overall communication and other aspects of this unit. It also has photos and audio along with my personal writing.
- 你学了什么?What did you learn from doing this work?
I learned more about grammar and the format of writing speeches. I also learned how to pronounce things fluently in order for my video to have a better flow.
1. Give a brief description of an oil spill and how it can be cleaned up using science
An oil spill is when liquid petroleum hydrocarbon leaks out onto an surrounding environment usually causing damage and harm. However, thanks to science we can now clean up with lots of different methods like oil absorbing pompoms, sorbents, skimming, and steel mesh. Focusing on the steel mesh, it’s superoleophobic (takes out the oil, leaving it on top, letting the water through the mesh). The design is based off lotus leaves are that they are superhydrophobic (leaves water behind, oil passes through), materials can be developed into non- hydrophobic materials by making the surface rougher which reduces surface energy. The mesh consists of layers. The first has a surface with polymer with surfactant (helps soap and detergent to clean) built inside. On the outside layer of steel mesh, nanoparticles of silica help to increase the surface area and improves the ability to repel oil, mimicking the lotus leaf. Fluoro-surfactant seals the entire mesh. The mesh could be made into a huge net for cleanup to skim the water, or used as a filter for contaminated water.
2. Is science good for humanity? Do the benefits of scientific discovery outweigh the problems it causes?
Science can be seen as a advancement for humanity as many great innovations have been made such as medical advancements like antibiotics which help us to fight off disease and bacteria. Medical advancements also increased our life span and mortality rate and helped us understand and detect diseases like HIV. Next, electricity also helped us create many other innovations such as modern technology and gave us a better source of light instead of the dangerous fire which is a hazard. Finally, the final advancement is the building of the industrial revolution which started the production of items on a mass scale. This led to more jobs, and more available products to the public.
However, there are negatives to scientific discovery such as the mass scale of overproduction and global warming (from the industrial revoulution), the extinctition of animals (humans discovered their properties, and hunting began: ie. elephants and ivory), and the potentially dangerous chemicals and weapons (nuclear weapons which have a lasting impact on our environment.
In conclusion, Science is equally good and bad, and scientists are careful to consider the impacts of new discovery.
|Inspiration and Research Info|
|Criteria A – Knowing and Understanding
ii. Demonstrate knowledge of the role of the art form in original or displaced contexts
Important info from link:
After learning about bpm, this tutorial shows a simple but well done way to match the bpms of the different songs. This matters as without correct bpm the song ends up clashing and sounding very strange.
Important info from link:
Some important information I learned from this is how to set up a basic mashup and how to do it specifically in garageband. It also showed me the basics like instrumental and acapella, as well as the fact you have to have bpm.
Important info from link:
This is a more overall/completed tutorial using tools such as audacity and shows the complete process of the mashup. This also explains the mashup with details and how mashups work in general.
Important info from link:
This is a mashup that I was inspired by as it has many songs yet manages to sound like one song and flow smoothly. It also has lyrics that match well even though there are many songs.
|Criteria C – Thinking Creatively
i. Outline a clear and feasible artistic intention
|Goal: My goal is to make a successful mashup using 4 different songs using garageband. I want to successfully blend the songs together and make it sound whole/consistent. I also want to use proper technique within the creation of the mashup and have the song be on the same beat throughout the entire song.
Outline/Process (Steps) to Achieve Goal:
Why this project?: I chose a mashup up as I like listening to mashups and I think mashing up 4 very different songs is an extremely interesting idea. I also like editing audio/videos in general and enjoyed the music apple loop songs that we had to do in class for work.
During this unit, I improved on developing/learning ATLs. I used thinking skills in this Food Issues Unit was the research into the issues and analysis of my personal food journal. These required loads of in-depth research as well as reflecting on my cumulative results. I used my research skills was talking about food issues, my research skills became more developed. I learned how to make use of databases/WebPathExpress in order to find more effective and relevant materials for my project. I used my social and communication skills to practice and revise my slides with other people. I also further developed a skill of learning how to recite knowledge and actually learn about issues rather than read directly off slides. I used communication to clearly explain my food issues and explain them concisely. I made a huge improvement in self-management skills, as I evenly distributed my schedule, unlike last year.
What makes a credible scientist?
Credible scientists must have knowledge and an open mind. Knowledge is important as you need to have previous knowledge if you want to be credible as you can’t just make up scientific information. You need to have a good background in science. Research with knowledge is also important as you want to make a hypothesis/claim you need research to back it up. Otherwise, there is no proof, therefore making it not credible. Open minded is also important as if you try and force an experiment to match your hypothesis, you are not being accurate or credible.
Why is the scientific ‘way of knowing’ used in medicine compared to other ways of knowing?
The way of knowing is medicine can vary in a lot of ways, ranging from factual to spiritual. For example, for some people, if they get sick they may perhaps head to the doctor for medicine. However, some other may believe with methods like acupuncture, praying to a god, and other rituals. In typical science, we rely on factual methods however as you can see in medicine we rely on other methods.
Reflecting on scientific investigations is important because you can get more accurate results by repeating investigations with improvements to your method. How would you improve your seed dispersal investigation if you were to repeat it?
I would improve the investigation by being more careful and making sure to add labels to the charts/graphs. I would also be more in-depth with analysis and the metho analysis. In the future, I would also try and follow the methods better.
