15 Mins Of Fame Unit Reflection
Energy Unit Reflection
I think in this unit and through my paper, I was able to demonstrate the learner profile thinker because this unit was a bit more of an opinionated project. This meant that I was given more freedom to really think about what I personally thought was the best source of energy, and what I thought was going to be the energy source of the future. I wanted to make sure that I honestly believed in what I was writing about before I wrote the paper, so I made sure to really think about the advantages and disadvantages of each energy source before I wrote about them. For example, yes, renewables will greatly help the problem of global warming and help climate change (main problem we face/the reason we are looking at other energy sources in the first place) but renewables take up a lot of space while still not being as effective as other sources of energy. Nonrenewable forms of energy are also a big risk to put all our effort in because they produce waste, like how nuclear energy produces nuclear waste. However, they are able to be a lot more efficient and reliable compared to renewables. I think the main thing I took from this unit is the fact that we as a society have to really think about what’s going to be best for us to not only preserve our planet but still be able to further our development/growth. We have to think about and consider the benefits and consequences of using each type of energy source and should use a combination of all types of energy sources to maximize efficiency. The problem with the industrial revolution and the burning of all that coal/oil is that we only used one type of energy and did not invest in any other forms of energy, so now we’re running out. We need to realise that if we only use one type of energy, we’re going to run into the same problem again and again. It’s only a mixture of all types of energy sources that will be the best solution.
I’m most proud of the organization of my essay. I think I did a really good job with separating my points into sections; introduction, background, environmental considerations, etc. The organization of the essay and the way it was arranged helped the development of the readers’ understanding of the topic and how easy it was to understand and comprehend the essay. The way I wrote it made it so that they were able to have an overview of the topic, understand how it works, then have the 2 explanations of why I think this is the best energy source and a conclusion. I was also really proud of how I was able to keep track of all my sources. Usually, I lose track of some sources, or can’t find where I found the information, so I think keeping them all on one doc really helped me to trace the information back to where I got it from.
Like I mentioned in the first paragraph, I firmly believe that all forms of energy are related and that using any energy resource has both positive and negative consequences. Using too much of something is never a good idea of course. That’s what happened with coal and oil. We were focused on reaping the benefits of all the energy we got to the point where we disregarded the fact that using so much can have drastic consequences on our world. I feel like when humanity first started using coal/oil that the possibility of using too much was too absurd and unimaginable for them, but then as cities started growing and we started to rely on constant energy to complete daily tasks, energy became a neccessity and it was too late to stop. This is why we should put our time and resources into all types of energy sources.
Bias in Media Summative Reflection
Throughout media, bias and stereotypes are hidden and disguised, but they still affect our perceptions of society. We learned a lot from this unit, how to look for the real purpose of bias, why people use bias, and how to avoid it. But something we should take note of is that no matter what, bias in media can alter perspectives and influence an individual’s opinions. That’s not always a bad thing though, because sometimes it’s necessary for us to change our mindset in order to move forward as a society. How necessary is bias then if it helps us move forward as a society? Read about it in my reflection of our bias in media summative:
Unit 3 Work and Machines – Summative Reflection
How much did you know about Work and Machines before we started? I didn’t know too much about work and machines before this unit. I think most people, like me, go into the unit expecting work to be the regular or normal definition of work, not force*distance, so it was a bit confusing to get used to at first. I also think that my knowledge of machines has increased dramatically. Before, I knew the basics of how simple machines, like what a lever is, what it looks like, but I didn’t really understand how a lever works and how it’s defined. So things like that were made a lot more clear during the unit, especially since I really think about how simple machines were all around us in real life, like how a screw is made up of an inclined plane.
How would you improve your Inclined Plane Lab report? In my inclined plane report, there could’ve been more detail in explaining my data. Most of the time, I compared the data, but I didn’t go into a lot of description about why they came out that way or way the data was like that. The logic behind some of my reasoning was also flawed and not well supported.
Discuss what would you like to study more about in this unit? Why? I think because we only focused on one simple machine for our GRASP project, I would like to know more about a different type of machine. The one that interests me most out of the 5 left is the lever because there are a lot of different projects you could do seeing as there are different kinds of levers, so exploring different types of levers and simple machines would be what I want to continue studying most out of this unit.
Thinking about work and power–how do you think they will relate to the next unit–Energy? Obviously, from our unit, we already know that work and energy are very closely related because work is basically the transfer of energy. Work is done when energy is transferred onto an object and the change in kinetic energy is equal to the net work done on an object. Power is also related to energy because some units of energy use things like kilowatt-hour. Using one kilowatt-hour of power, energy can last up to an hour. It will be interesting to see how the things we learned in this unit, work and power, relate to our next unit on energy.
Equity and Advocacy Unit Reflection
Below, you’ll see the reflection I did on this semester’s unit, Equity and Advocacy. I talked about the things I learned, what I enjoyed, and how I felt about the unit in general.

Unit Reflection: Journalism
In this unit, we learned all about how to analyze the style, content, and technique of a news article or news media. There were a couple of different activities we did in order to practice annotating news articles for those kinds of things including; watching CNN10 then annotating on its style of presentation, annotating a news article for both the author’s craft and content, and writing our own article about an issue that affects people like us (other students or people in our community). Here’s a reflection of what we did in this unit:

A Brief Overview of Mitosis and Meiosis
In this unit, we learned about cell division and cell reproduction, mostly through the process of mitosis and meiosis. Mitosis occurs whenever more cells are need and can happen in animals during regeneration or during asexual reproduction. During mitosis, the cell is able to duplicate itself and make another cell that is exactly the same, including the same DNA, genes, everything. There are 6 different phases that occurs during mitosis in order for the cell to copy itself: interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. In interphase, there are 2 different stages that happen; the G1 and S stages of interphase. In G1, that’s when the cell gets bigger and the cell starts to prep itself. Then directly after that, comes the S stage of interphase, which is when the chromosomes all make an exact copy of themselves (called sister chromatids). These sister chromatids have the exact same genes and structure. There’s another growth phase in interphase called G2 that happens, but it’s not as important. Then comes prophase, which is when the chromatin condenses and you’re actually able to see the chromosomes. In interphase, since the chromatin wasn’t very tightly packed together, you weren’t able to really see the chromosomes yet. It’s also between prophase and metaphase that the nuclear membrane disappears, which will come in handy during metaphase. So in metaphase, things called centrioles will move to the opposite ends of the cells and microtubules will come out from the centrioles and attach onto the centromeres of the chromosomes. This is able to happen because the nuclear membrane has dissolved, and the chromosomes, which were previously inside the nucleus, are now just in the cell and no longer protected by the nuclear membrane. The microtubules will eventually develop into spindle fibers. The spindle fibers tug from the opposite poles of the cell in order to get the chromosomes to line up directly down the middle of the cell. Now comes the anaphase part of mitosis. In anaphase, the chromosomes break at the centromeres, and the sister chromatids are pulled to opposite sides of the cell. In telophase, the nuclear membrane reforms around each group of one half of the sister chromatids on each side of the poles. The nucleoli will reappear and start to decondense back into chromatin. The last step is cytokinesis. In this phase, the cytoplasm should divide in 2, creating the 2 new daughter cells.
Meiosis is slightly different because instead of wanting to duplicate the cells, you want to create genetically different cells. The process is still similar to mitosis although you will end up with 4 daughter cells instead of 2. The beginning is roughly the same. It first starts with interphase, where the DNA duplicates itself. However, now we go into prophase 1, where homologous chromosomes pairs (maternal and paternal chromosomes with the same length and genes in the same place, however, there can be different alleles for each gene) come together so tightly that they might switch genes. The process keeps going, metaphase, anaphase, telophase…but instead of stopping there, then the process starts again with the 2 daughter cells at prophase 2, then goes into metaphase 2, anaphase 2, telophase 2 and this is what’s able to create the 4 daughter cells. In males, each of the 4 cells will become a sperm, however, in females, only one chosen cell will become the egg. This is important because if you remember in prophase 1, in meiosis, the homologous pairs are so tightly wrapped around each other that the genes sometimes swap. So when anaphase occurs and pulls these new sequence of genes to the different daughter cells, there’s a chance that one of the new sequence of genes in chromosomes that carries an undesirable disease has ended up in the one chosen egg.
This unit was interesting to learn about because we were able to discover a lot about ourselves and why our DNA came to be the way they are. It was also really cool to see how certain people come to have a mutation or inherited disease through looking at the DNA and their parents’ DNA. We mostly studied using the different directed reading worksheets that quizzed us on what we learned in class/the textbook but there were also a few informative videos we were able to watch that really helped us to understand what was happening in the 2 processes of cell reproduction. There have been current advances in genetic technology and scientists are currently working on a method that will allow them to be able to take a mutation in someone’s gene that causes them to have a disease and to cut out that specific gene out and replace it with a normal one. This is way more advanced than anything before because it’s actually stopping the root of the disease and not just giving the people drugs that will help combat the symptoms of the disease. The future of genetic modification is rapidly approaching with the help of advancements in technology and this will help people, especially ones with life altering diseases to live, not just survive.
