So far into 2023, I have read two novels, one fictional and one non-fiction, which is Outliers and Call of The Wild( the book I am currently reading). Personally, Outliers have impacted me a lot in the ways I think. It has helped me reflect on what is important to the success and how to accomplish them, and the reasons behind this. For example, I lesson I learned that not everyone who practiced for 10000 hours could be a master violinist, but every master violinist has practiced for more than 10000 hours. On the other hand, Call of the wild didn’t teach me a lot of life lessons, but the book helped inspire more ways of writing. Not just unpresented and fascinating vocabularies, I learned deeper about the interesting use of short sentences, conjuring sentences, and third-person descriptive. Overall, I have been slow in reading because of two reasons. First of all, the books I have been reading over the year are all quite challenging. Taking 3-5 minutes a page could be regular. Equalling, are the difficulties of the vocabulary. Second of all, which is a problem I should correct as soon as possible, I don’t finish a book. I didn’t finish Messey, nor did I finish The Spy. I might stop for 2-3 days because of exams. All in All, in a simple way, I should try harder.

A rubber band car works by converting potential energy stored in the stretched rubber band into kinetic energy of the car’s movement. When the rubber band is pushed, it gains potential power, stored as elastic potential energy. When the rubber band is released, it contracts, and the potential energy is converted into kinetic energy, causing the car to move forward.
The transfer of energy in a rubber band car can be explained through the principle of conservation of energy. According to this principle, energy cannot be created or destroyed but can be converted from one form to another. In the case of a rubber band car, the potential energy stored in the stretched rubber band is converted into kinetic energy as the rubber band contracts, and the vehicle moves forward.
Initially, the rubber band car is at rest, and all its energy is in the form of potential energy stored in the stretched rubber band. As the rubber band is released, the potential energy is converted into kinetic energy, which causes the car to move forward. The vehicle’s kinetic energy depends on its mass and the speed at which it moves.
After the last change, the rubber band car is working perfectly fine(mostly). What we thought was interesting was that we could change our car’s engine level(how many rubber bands a time). However, there are still parts we can improve on, such as the decoration and the wheels(they move wobbly )
It is perfect for the environment as it causes no environmental damage, is purely green energy, and is reusable(it doesn’t need a battery.) The best audience is students who have just started learning about energy because this is a fun/exciting, and very visual toy that can show the convention of energy.
this is our current product.
After showing it to Micheal and Eugene they all bring up a problem which is the car automatically stops itself because the rubber band is stuck on both sides after is finished with the rotation it does not fully use its energy. Mr Hussack said that maybe we can look into how toy cars work. Also, sunnie(who is also doing a rubber band car) told us that the most probable way is to just not let the rubber band be tied to the engine, only to the car.
our plan is to tear the rubber band off. set the anchor to somewhere further ahead and not tie the engine this time.
our plan is to complete the main body and the wheels attached by the second lesson, we will be in the wood working space
everything was put together in thee the third lesson, mainly around the space with hot glue.
ask for feed back and what could be improved in lesson 4
lastly, last modify and changed made in lesson 5
I am making a toy that represents the transfer of energy.
some ideas that went through use were:
cross bow
pro: pretty cool
con: many people doing it, not creative, dangerous-not very well for educational purposes
rubber band car
pro: easy to use and understand.
con: easy to break
handshake the light bulb
pro: can make the students feel the consuming of energy/resistance there
con:just not very cool and creative
and a self-design that includes mixing the structure of saving energy in a music box and a light bulb together.
pro: very unique, probably only in the school every existed
con: no one has done it online, so if I had a logical mistake, no one can correct me
in the end, we decided to use the rubber band car because it is easy to make, reliable and the energy transfer is observable with the naked eye.
three videos we watched were:
my targeted audience is students who just begin learning about the concept of energy and power.( this product can also help represent how energy became power). As energy is not observable by the naked eye and is a new topic, somethings it is challenging to understand as a student. the product can show the energy transfer and is fun in the same time,
The big thing I learned from the improvising unit was to try my best every time. Before, I used to only do something when I think I have a big chance, almost sure that I can get it. I used to avoid answering questions I’m not sure of, getting away from tennis matches even when I am better than the opponent. now after the improvising unit, I gained more confidence in myself. Now even if not getting what i want is the bigger chance i would still give it a try because now i know even if i fail nobody is going to laugh at me or make fun of me. And this huge improvement in my attitude is going to stay with me for the rest of my life.
1. risk taker
2. positive and energetic
3. aware and in control
4. focused
5. active listener
6. cooperative and collaboration
7. efficient
8. leaders&followers
9. positivity critical & able to act on that criticism
I want to work on being a risk taker. Somethings I am scared and unconfident when standing up for something because I don’t know if I am doing the right thing. It is not hard for me to do a speech or act in front of an audience, but I need to confirm a lot of times with other people every time if I was doing the right thing. This improvising unit is an excellent chance for me to improve on being a risk taker.
Our modern-day heavily relies on burning fossil fuel for electricity, from the light and air conditioner in your house to your phone or car that you use with you every day. In 2019, in America, 66 percent of the electricity was generated by burning two types of fossil fuels- natural gas and coal. Natural gas (38percent of the electricity generated) is estimated to be running out in 54 years, and coal (28 percent of the electricity generated) is going to run out in around 100 years. (MET group counties for when the type of fossil fuel will run out and Yacoubou for the percentage of how the energy is being generated) Furthermore, With the help of a tech-savvy 3-D model of atmospheric chemistry with a high spatial resolution that analyzed pollution globally and found clues leading to its impact on human health, a recent joint study by universities discovered that one in five deaths in 2018 — that is, 8.7 million — was caused by fossil fuel air pollution. (Hwan) It is fundamental for us to step into the age of clean energy.
http://www.fjsen.com/i/2013-03/12/content_10843444.htm
It is going to be incredibly hard to instantly change all the countries in the world to be using clean energy. Developing counties will be struggling as manufacturing prices and transporting between counties or others will all be problems, but things need to be accomplished step by step. The first step, and easiest, is to reduce the use of energy produced by burning fossil fuels, which causes pollution at the same time, to using solar panels. (Hydroelectricity requires flowing water; wind turbines require large flat land not possible in cities); geothermal requires specific land and costs enormously. Since solar panels can be placed anywhere and are possible to be affordable by individuals, solar panels are the best)
So how much can solar panels help? Typically, a residential solar setup produces anywhere from 350-850 kilowatt-hours (kWh) per month. The average home uses approximately 909 kWh of energy per month (according to U.S. Energy Information Administrations), so owning solar can save you upwards of 90% on your monthly electric bills by replacing it with clean energy. A real-life example is China, the world’s largest installed solar energy fleet, measured at 205 GW in 2019, according to the IEA’s Renewables 2020 report. In 2019, 7.5 trillion kilowatts of electricity were used ( Statista Research Department) and 223.8 terawatt-hours were generated by solar energy(NS Energy Staff Writer). Which is 2.8 percent, despite other ways of clean energy generated, it is an incredible number even though it might not sound to be a lot. Therefore, solar panels can save you money and help the environment at the same time but why aren’t people using them? The cost is a big obstacle that stands in the way. A single setup of solar panels could cost around 20000 US dollars (Blue raven solar) while, even in rich counties like America, the average income is.
But how can we get the most affordable solar energy? Because of its cheap and efficient manufacturing ability, China is producing the most affordable solar energy and panels globally. A typical capable company is Sun Teach. In 2004, solar energy cost about $3.20 per watt, on average, to make silicon solar panels. By now, according to solar- industry analysts at Photon Consulting in Boston, a Chinese manufacturer can make them for as little as $1.28 per watt, while the lowest-cost Western manufacturer will produce comparable technology for about $2.00 per watt. (Bullis) Furthermore, it will get even cheaper in the future because things get cheaper when there is a higher amount of it.
one severe problem is that after the manufacture in China is cheap but, when the solar panels are transported around the world, the pollution is balanced. Despite the time needed, the railway is overall the cheapest and causes the least carbon footprint. (also seldom have accidents that delay) The railing is one of the cheapest ways to transport, a little more expensive than trucks. Railing goods are far cheaper than planes and a little cheaper than the sea. Most importantly, the railing is very eco-friendly. national rail only produces 41g of carbon dioxide per km while flight could cause 154, almost 3 times less carbon produced). ( Ritchie)
https://ourworldindata.org/travel-carbon-footprint 
European Union Commission has declared 2021 the “Year of Rail,” and the EU Green Deal framework published in July 2021 calls for a substantial shift to rail, with the “Smart Mobility Strategy” stating targets of a 50% increase in freight in the EU transported by rail by 2030 and 100% increase by 2050. (Christoph ) With the less fuel required and pollution caused, rail can carry far more goods than trucks. Transporting solar panels can be forced on China, as the first step , since the largest fossil fuel consumer is China, almost doubling the amount of U.S.- 145.46 exajoules of china and 87.79 exajoules of U.S.( N. Sönnichsen). Using rail to transport will turn the transport of the solar panels clean and affordable too.
Some people argue that the money spent on getting a set of solar panels is not worth it, since it might take up to 10 years to yield a return. But we must keep in mind two things: First, and most importantly, all the energy that you use in that home over the years is all clean, which means no fossil fuels are burnt for it , which means no pollution at all is caused. “Which balance the cost if you are thinking this way.” quoted Mrs. Paola; Secondly, Mrs. Paola said that as long as the demand for this technology grows, prices will continue to drop.
Ultimately, solar panels are the best way to get clean energy for individuals. Problems such as price and pollution when made/transported exist , but there are solutions to them making solar panels more accessible than others like hydroelectric, geothermal, or wind. (With the advantage of being able to be used anywhere without a big demand for land) Steps need to be taken for our world to stay clean and safe. Using solar panels isn’t the first, nor would it be the last.

We were writing about a historical fiction journal based on true events. the journal needs to balance between narrative description and the facts and the events that really happened. We also need to show the internal or external conflict of the character. Lastly, we need to write about the causes and effects of events, also there could be multiple effects of one cause or the opposite. My character is a normal peasant who lives close to the border of the country( not very affected by the revolution)_.
The video had taken a surprising length amount of time, it took a lot more time than we expected. We predicted it would have only taken around 1-2 lessons, but I have slapped us on the face, and turn out that we even need to take extra time at home to get the video done. I have gained a lot through the process of making the video even though, there is a lot of times when we had a conflict between our ideas. I had learned how to cooperate with all kinds of people. The second thing that i learnd was that making video take a lot of effort
