How science can cause and solve environmental problems

  • Give a brief description of an oil spill and how it can be cleaned up using science.

Oil spill is the release of petroleum hydrocarbon into the environment, especially in the marine ecosystem. Usually caused by accidents involving tankers, barges, pipelines, refineries, drilling rigs, and storage facilities. Around 1.3 million gallons of oil are spilled just in the U.S in a year. Although scientists had figured out ways to clean them up such as using booms and skimmers, in situ burning, or even leaving them alone, but none of them are friendly to the environment and the company also loses all of the oil.


  • Is science good for humanity? Do the benefits of scientific discovery outweigh the problems it causes?

Yes, science is beneficial to humanity. Without it, we would still be stuck in caves and living a short lifestyle. Although it brings pollution and destruction, it gave us cures to diseases, stable food and water sources, building to live in; it brought the world together, we are better as a society with science. An example might be the creation of the internet. The Internet is a huge part of our lives now. It brings the world together through a tiny device, reduces mental stress, and its a great source of information, you can find anything with it. People do get scam online, but more people benefited from it compared to the victims. Plus people can always find a way to trick people, it would still be the same without the internet. The internet is actually a great way to spread information about how to prevent being scammed.


Design Lantern Reflection

Q: What are some cultural considerations people make when designing products?

The designers should ensure that the design is not offensive to anybody especially the intended consumers. The language and the symbols should also be ensured that they have the right meaning in other cultures because things can be very different in different society. In the process of making this Chinese lantern, we checked in with our Chinese teachers to make sure the language and symbols we were using are appropriate.

Q: How does the design of a product communicate traditions and values?

Design can communicate traditions and values through words and symbols. In this project, I wanted to pass on the message of good luck so I wrote 万事如意 which have the the meaning of “May all your wishes come true”; and I drew a tiger in the middle which symbolizes power, and bravery but also lucks and peace in Chinese culture.

Q: Are handmade products an effective way of minimizing environmental impact?

Handmade products are neater and it means a lot more when it comes gift giving. But in terms of environmental impacts, no it’s not the best solution because in large companies, they could minimize their waste by reusing a lot of the left over materials; but when you are doing a handmade product, you have to buy everything and often you are only going to use it once which is wasteful.


Car Park

In today’s lesson, we learned about Algebra and had used Student Desmo lesson central park for practices.

Algebra gave us a solution for all of the similar problem.

For example:

Without it, we have to calculate one by one which is time-consuming and most of the time not accurate

Mashup – Project Genesis


2002 – Anne Marie

Darkside – Alan Walker

Girls like you – Maroon 5

Oops I did it again – Britney Spears

Happy now – Zedd



Explain the process of this assignment. *
For this project, we are allowed to choose something that we are interested in, and the majority of us choose to do a mashup. Since I have never tried mashing up different songs together, I did some research before starting the project; searched up some examples of mashups, learned how to change the bpm of a song so everything will be on the same beat, how to make smooth transitions, etc… After that, we started collecting the songs that we are interested, and altering the bpm so they will be on the same beat. After all of those, you can finally start mashing up the audios. I actually did 2 mashups in total for this project. I spent almost all of the time on the first one, but because of the styles of the songs are too pluralistic, they don’t fit together that well. After spending the last work period trying to fix it, I realized that it’s better to just create a new mashup. And I basically redid everything from the start and got it finished in time.
Discuss your must-haves and desirable qualities here… *
In my project, I must have 4 songs with the desirable qualities of a similar style; smooth transition in between those songs, such as lyrics connection; have the same bpm per minute, every note should be on beat; have multiple uses of tracks at least twice each; the length of the mashup has to be more than 3 minute. I did qualify for all of the Must-haves, although I could have done better with transitioning. In class, we talked about how we are supposed to loop the different part of the song into another instead of simply playing and switching in between different songs.
Evaluate your learning and new skills acquired. *
I am making a mashup which is something that’s brand new to me, and I had to do some research before making this project. In the process, I had learned how to change the bpm of a song, how to make smooth transitions in between the songs and had searched up a few examples to give me an idea of what I am making. I also need to apply the information I just learned into making the project, put my research into good use.
What challenges did you face and overcome? *
When making the mashup, I had picked songs from different genres with no connection which made it hard to make hard to mash them together. Most of the time, songs with strong bass are easier to use while making mashups, but the majority of my choices have slow temples without strong beats. After a few hours trying to fix and alter every single audio I have, I have decided to go with some fast-templed, light-hearted songs. I had deleted everything and work from scratch again, although I didn’t take me as long since I already know how things work.

Humanities – Unit 1 Summative REFLECTION – Food Issues

In this assessment, we mainly focused on ATLs skills, organizing, and making conclusions. We were given lots of time for this assessment and were supposed to make an action plan where we organize and break down the summative into smaller tasks to ensure you’re getting enough time to finish it rather than doing everything on the last minute. We also had to analyze our food journal, and make a conclusion about the impacts of our food choices. I think overall, I did a good job, especially on the research (food issues organizer) since I’m actually interested in those topics. But there are also things I found a bit challenging, such as making the action plan. I misjudged the amount of time I needed to finish my research and script, and everything was pushed behind by a bit. I had less time to revise my work than what I had expected.

Sound of CDNIS Music Assessment

Here’s my final project.




In this assignment, I wanted to give my audio an “old recording with little damages” feeling. First, I walked around the school to collect my sounds, and then I altered 4 of the sounds to fit the theme of this song by using bitcrusher and distortion to create the fuzzy effect. Then I cut some of the sounds out and leave a few beats blank, or even repeat some parts of a loop several times in a row to give a broken recording effect. I had also added in some midi instruments and loops to fill up some of the blanks, and create my own melody.

My CDNIS sounds are very useful for my end project. I gave the sounds an fuzzy effect and they worked out really well with the theme of the song. For example, the chains. It has the tinkling sound with a fuzzy background while not covering up the main melody.

I was inspired by some of the broadcasting stations in the taxis, which produces fuzzy noise when there’s no signal, it reminded me of the old tape recorder.

While working on this assessment, I had learned a few more things about the features in GarageBand. For example, I got to experiment with Bitcrusher a bit more since I need to use it for most of my sounds. I found out 4 bit almost works for every loop, it makes the audio harsh enough while still keeping the melody. Another thing that I improved is how I organized all of my loops. A lot of different loops were used in this assessment, to keep track of everything, I gave every sound its own track so when I’m altering the sounds or moving places, it won’t affect the others.

I had faced a few challenges while working, such as, there was always a problem with the audio. Sometimes, even if I close all of the plug-ins, it still plays the altered sounds. This is probably because I was adding too much affects without knowing how to properly use them and somehow broke the distance. to fix this, I opened up another project and redid a lot of the plugins after researching more about the effects and how to use them (including watching tutorials on youtube).

Reflection – Seed Dispersal Investigation

 What makes a credible scientist?

Valid data. In order to collect data that best simulate the real-life situations, we need a detailed method and multiple trials.

Why is the scientific way of knowing used in medicine compared to other ways of knowing?

The modern medicine is a fast way of treating a disease, the disease is tackled as a separate being from the patient. It’s precise and fast when fighting with a particular disease. In comparison, the traditional medicine is a good way to gradually build the body back to fitness allowing it to fight diseases on its own.  It doesn’t work immediately.

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

if I am going to redo the seed dispersal investigation, I will add a few more steps to the method to improve the accuracy of the results. For example, by adding a more specific instruction about when to release the cones, when there’s less wind), to control the CV wind better. We will also be ensuring the cones are facing down when releasing to improve the CV release position.
