How science can cause and solve environmental problems


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

An oil spill is the release of a liquid petroleum hydrocarbon into the environment, usually by human activity. Oil spill can destroy the environment and kill mammals. There are many ways to clean the oil spill using science, such as skimming, burning, chemical dispersing, corralling etc.

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

I think the amount of advantage and disadvantages weighs the same. With science, humans can live longer and safely, and we have an opportunity to explore the space. However, science does harm the Earth and it uses a lot of resources. The significant problem of today is that the Earth’s resources are limited and if it is once gone, it can’t be back. On the other hand, if we have further developed science, we might get new type of resources from space and develop our world even more.

Design Reflection

What are some cultural considerations people make when designing products?

When designing the product, we should consider the words and pictures that goes in the design, because it might be inappropriate, and might be non-sense.

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

Every single element in the design can communicate traditions and values. For example,  if the design product is colored in red, it means “good fortune” for Chinese people.

Are handmade products an effective way of minimizing environmental impact? Why or why not?

Yes, handmade products are an effective way of minimizing environmental impact. If we bought every element which probably are produced from factories, it means we are harming the environment because factories produce harmful gas that ruins the environment.

Math Car park

We did car park activity today, which was to find each area that could make the car fit. To find the area, I had to subtract the width of the divider from total width. Then, devide that calculated area from number of dividers + 1. Using this, I struggled and made a formula” (w-pn)/n+1 “which made me stop from time wasting. It was way easier for me to solve the problem with my algebra.

<– Using formula to solve 4 problems at once


I learned how to solve problems using algebra

My Mashup



Sorry I don’t know why it is over 4 minutes

Explain the process of this assignment. *
I chose to do mashup for this assignment, because I thought it will be fun to mix the songs. First of all, I looked around the internet to choose the songs that will be in my mashup. After I chose the songs, I converted them into mp3 file format, then put them into Garageband. After that, I played the two songs together (Havana and Friends-Marshmello) and find a good part of the loop that will have smooth transitions and interesting melody. I have also controlled the volume of the song for some songs. For example, I lowered the volume at the end of the very last loop so it ends the song nicely.


Discuss your must haves and desirable qualities here… *
My must haves and my desirable qualities were the smooth transitions between the loops, good melody, staying on some beat, more than 2 minutes and 30 seconds, and having lyrics that makes sense. These must haves will make my mashup more good.


Evaluate your learning and new skills acquired. *
I learned and I acquired some new skills. Before this assignment, I had totally no idea what mashup was. However, during this project, I got to know the definition of what a mashup is, and how to make a good mashup; getting to know how to have nice smooth transitions between the loops, staying on some beat, and connect the loops which the lyrics will make sense. These must haves will make my mashup more good.


What challenges did you face and overcome. *
I had to face some challenges for this assignment. It was really hard to connect the loops smoothly, and even though I connected it smoothly, the lyrics won’t make sense. Therefore, I spent a lot of time trying to make the loops to sound as a one whole song, caring about lyrics. This was the most challenging thing in this assignment.

Music research

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: This is the example of a classical music mashup. It shows how the mashup sounds like.

Important info from link: This gives me basic knowledge of a mashup. It explains the history and the definition of a mashup.

Important info from link: This is a useful link, because it gives a tutorial about how to make a mashup using the Garageband, which is a software I will use. I can get some ideas for my mashup from this video.

Important info from link:This gives me some great tips and requirements for making my first mashup. This tips might help me to create the mashup more nicely.

Humanities U1 Food Summative Reflection

During this first summative assessment in humanities, I learned a lot of interesting history and facts about the food. For example, in previous years, I never knew how much water that one pound of meat requires to produce, but I know now. After this summative, I understood a lot of impacts that I was giving to the environment, people, and the global Earth. Despite that I learned some interesting facts from this summative, I suffered a lot of challenges I faced while doing my research organizer and presentation. One of the challenge I faced was that I couldn’t keep up my action plan, because there wasn’t enough time. Also, while I was make this presentation, I was overthinking and feeling nervous about the presentation that I have to do in front of class. This gave me a lot of stress.

Music Criteria D Reflection

Describe the process of this assignment

First, I planned what will my music theme be, and then I started to plan what will I record. I recorded the sounds that were happening in CDNIS, and also outside of CDNIS. I recorded drilling sound outside, footstep, bell, and person whistling. After recording all of them, I briefly outlined my music. I actually made the end part first, which was the rock theme. However, while I was trying to figure out more details on Garageband, I discovered something called synth. I tried multiple of synths and it was very suitable for melody, so I used it for my music. This is how my music was created.

Discuss your CDNIS sounds and how useful they were for your end product

I used the footstep sound for the beat for my music, its job was kind of like a drum. The bell ringing sound was good for decorating the melody, and I used it like the cymbals in my music. I used the whistling sound to start my music with an impression. For the drilling sound, I made it to join the melody. I thought the drilling sounds like wind, which I thought it will be good with the melody.

Evaluate your learning and new skills acquired

I acquired some Garageband skills, such as using plugins, and finding out the new Midi instrument type”synth” how to play those (I thought there were only basic instruments in Garageband like piano, guitar etc). I also improved my knowledge of creating music. For example, I learned that usually, the interesting part should come out on beat 4, and I have to repeat some parts to make the listener to enjoy the music. I shouldn’t randomly put the loops. These were the some knowledge I got.

What challenges did you face and overcome?

One of my challenge I faced was while I was recording my sound, there were a lot of noises around me, so it was hard to record clear sounds.
In my music, I still can hear some background noises on some of my recordings, but I covered it by putting melody and plugins. I also suffered between the transition, because it wasn’t smooth enough. I made the transition smoother by overlapping the loops.


Science Reflection

What makes a credible scientist?

A credible scientists are made from how valid their experiments are. Their data, method, etc, should be all valid in order to be credible to people. Therefore, having a lot of trials, and a lot of thinking can make a credible scientist.

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

Because scientific way of knowing is more valid and it has more trustable evidence than other “ways of knowing”. Medicines are used to cure other people, so it has to be safe. People just can’t use random ways of knowing, like “traditional ways of knowing”, etc.

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 will improve my seed dispersal investigation by having different dependent variable, and writing my science report in detail. This can show people my process and thinking more.
