Overview  

In this science project, our objective is to create an object that can show signs of energy transfer. The finished product should reflect our knowledge about energy transfer and be environmentally friendly. In this define and inquire document. I will be investigating successful presidents that demonstrate energy transfer to conclude what I should be creating. 

Success Criteria 

Firstly, to create a product that can show energy transfer, a success criterion is needed to ensure the quality of my final product. The requirements should be straightforward.  

-The product should be convenient to play/use.  

-The product should be environmentally friendly  

-The product should show energy transfer 

Energy transferring products. (A key switch)  

A product that shows signs of energy transfer is a mechanical key switch. It is a fitting example of potential and kinetic energy. Firstly, the gravitational potential energy is static. When the user applies kinetic energy to the switch, the spring will trigger the key to move downwards, resulting in a clicking noise being heard. When the button is released, the kinetic energy stored in the spring will cause the keycap to move upwards. To make this product more viable, we could make it very portable to carry it around and use it as a fidget toy.

Energy transferring products. (Fidget spinner) 

A second product that shows signs of energy transfer is a fidget spinner. A fidget spinner is used to relieve stress and procrastination. The spinner could help people focus and is used as a toy. This design fits our success criteria because it is a convenient toy, and it could be environmentally friendly with some modifications. The fidget spinner shows the energy transfer from kinetic energy to heat and friction.  

To begin with, the kinetic energy is applied to the fidget spinner as the user spins the spinner. Next, the kinetic energy slowly transfers to heat and friction because the bearing is rubbed on. As time moves on, kinetic energy will share most of its energy to friction and heat, resulting in a decrease in speed. Eventually, there will be no more kinetic energy, and the spinner will stop spinning. To meet both of our success criteria, we can make the product more environmentally friendly by using plastic residues to create the entire body of the fidget spinner. Furthermore, instead of using standard bearings, we can create a wooden bearing using fusion 360 to make our product more environmentally friendly.

Energy transferring products. (Toy car) 

A third product that can show energy transfer is a toy car. The toy car is an excellent example of the energy transfer between kinetic energy to heat and friction. To begin with, the potential kinetic energy is transferred into kinetic energy when we push the car. When the car starts rolling, the kinetic energy will transform into heat and friction and eventually burn all the kinetic energy, and the vehicle will stop moving. Toy cars are exceedingly popular because they are very sensorily engaging. It teaches people how their actions can make something happen. To make this car more environmentally friendly, we could replace the vehicle’s plastic and use wood instead.

Lastly, a product that can show signs of energy transfer is a fidget cube, A fidget cube helps people to deal with stress when they feel overwhelmed. The fidget cube is a very convenient and handy toy because of its size and more importantly, it can show signs of energy transfer. The energy transfer involved in this is kinetic energy and gravitationally potential energy. Although this product seems simple and relatively easy compared to the presidents, it is extremely difficult to build because there are many sides to a fidget cube.

In Robin Brande’s book entitled: “Fat Cat.” The protagonist cat initially believes that she isn’t loved because of her physical appearance but later understands that true love comes from within. This book connects to me personally because, in the story, Cat overcomes many challenges such as academic problems and social anxiety. Conversely, I did not have social anxiety, but I sometimes struggled with academic issues. Also, this book mentions a lot about science which may be an exciting category some readers are looking for. After reading this novel, I realized how much a person could change if they try hard enough and work hard. For example, at the beginning of the book, Cat is laughed at by other kids because of her appearance, but after having a diet, everyone has a different perspective of her. I recommend this book to people who have social and appearance anxiety because, in the book, the protagonist deals with these problems in various ways. I also suggest people that have relationship struggles come and read this book because it gives excellent relationship advice. Lastly, this book also has a lot of exciting topics, such as self-awareness and how to overcome them. For instance, on Page 206, it talks about how the Cat did not want to swim because she looked “fat,” but on page 256, she realizes the opinion of others doesn’t matter. Overall, this is a great book, and it was very entertaining to read. 10/10

1. 1. Close up of the hands. For my first shot, I filmed my hands playing with the camera.
   2. Closeup of the face. For the second shot, I framed it well enough so I cut off the top of the head.
   3. Wide shot. For the third shot, I took another video of me just chilling with my camera but further away.
   4. Over the shoulder. For this fourth shot, I took a video of me putting the camera back to the case.
   5. Unusual. I took a weird angle of myself leaving the classroom.

1. I have created an electronic bookmark that can light upon command. I added a frying pan to my design because I like a game called PUBG and the symbol of PUBG was a pan so I decided to add a pan as my design.
2. I choose to make this project because I enjoy the game PUBG so I decided that I would make something I enjoy and like.
3. I originally had 3 designs, one with the symbol of the sun, one with a symbol of a character called vigil, and last but not least a symbol of PUBG. when I finished planing I realized that the vigil symbol was way too hard and complex and the sun symbol didn’t look visually appealing so I decided to work on the PUBG pan, which was a cool and unique design.
4. My 3 designs, (vigil symbol at design 1 PUBG pan at design2 Sun symbol at design)
   
5. My prototype of the PUBG pan

6. My Design laid all out ready to stitch

7. My project finished

8. I have done some regular sewing but I have never done sewing with conductive thread. Sewing with conductive thread for me was a fun experience.

9. One thing that got me overwhelmed was the fact that I needed a lot of conductive thread because what I thought was enough was actually not enough so midway through the sewing, I could sew anymore because I had too less thread. To overcome this issue I realize that I should take a lot more even when I think it will be enough.

10. I would tell the students next semester to try to speed up with the paper circuits so that they can have more time with sewing projects.

11. I would want to learn how to code the lights because it seems very cool.

“When will the coronavirus end”, this question has been asked many times. Some experts suggest it may naturally disappear like the SARS, another group of experts believes the virus will last for 12 to 18 months until we discover vaccines, a third group of experts thinks that the coronavirus wouldn’t end until we develop herd immunity. In this blog, we will be digging into the theories to see which one is most likely correct.

The first theory is about COVID- 19 can naturally disappear like the SARS. The first evidence rebutting this theory that there is currently no decline in the total cases around the world for example in America the virus is not stopping. The deaths and confirmed cases continue to grow. Other places like brazil are also having a lot of deaths and confirmed cases  Some people might argue that china has stopped the virus from spreading, I agree with them however if the rest of the world isn’t doing so great, it doesn’t prove much. The second evidence is the fact that SARS died out in the summer and right now, the season is summer, and the coronavirus is still spreading. This theory has now been proven incorrect, and now let’s move on to the second theory.

As you can see the photos are from the European Centre for Disease Prevention and Control (ECDC) the first photo is in the united states and the second one is in Brazil, they both show no decline in the cases

The second theory suggests that the virus would at least last for 12 to 18 months until a vaccine develops. The Washington Post, a reliable news source ask scientist Peter Hotez why vaccines take a long time to develop, he tells us that vaccines and not profitable and funding for the vaccine would be difficult, he also suggested that even if the doctor has the funding, and the coronavirus ends then a lot of the vaccines will become stockpiled and wasted. He also says that some vaccines might backfire on the patient due to the virus’s DNA strand constantly mutating. For example, in the 1960s there was a respiratory syncytial virus aka (RSV). It was a virus that only infants could be infected with. When the scientist developed a working vaccine, the virus mutated which cause the vaccine to make the illness worse and cause 2 children to die. He also states that the coronavirus might end up like the flu where you have to take shots every year. Even though engineering a vaccine would be difficult, it certainly can stop the coronavirus. This theory could be considered correct and can be one of the possibilities of how the coronavirus might end.

The third theory says that the coronavirus might never end just like the infectious disease measles. The only way where our lives can return to normal is through herd immunity or vaccine development. Vaccine development issues were talked about in the second theory, so I am going to move on and talk about the problem with herd immunity. As scientist Suman Bhattacharjee, a man who majored in epidemiology and is the founder and head of Shomu’s Biology education states that there are 2 methods to herd immunity, the first method requires a long time to develop. Because it is required that at least 80% of the entire population to be infected with the disease and getting cured naturally without vaccines, once you get cured naturally, your body will start knowing how to counter the virus. This method may need to be repeated more than twice, during this prosses, less than 10% of the population will die. This method to achieve herd immunity is grueling but viable and will not be considered as an option to stop the coronavirus. Another way to create herd immunity is by mass-producing a vaccine and giving it to 80% of the population. By giving the vaccine to at least 80% of the world. The 20% will automatically be immune to the coronavirus. An example I made so that you would have a better understanding would be, if 100 people were living in your community, and 80 of them were vaccinated then the 20 people are not vaccinated. The non-vaccinated people are going to be protected by those who are vaccinated because the vaccinated people far outweigh the non-vaccinated people in numbers.

Now that I summarize the 3 theories. I predict that the second theory is the key to stopping the coronavirus because it takes the least time to solve the coronavirus, I also think that the second theory made a lot of sense and provides a lot of information with reasoning.

AS you can see the first layer is the crust, the crust is around 50 km and the ratio of the km to cm is 260km to 1cm using the ratio, we can find out that the crust is approximately 0.19 cm moving on the lithosphere is 140km away from the crust and again, using the ratio we know that the lithosphere is about 0.53cm long.  The mantle is around 2900km away from the crust so using the ratio the mantle is 11.1cm, up next we have the outer core, the outer core is 5100km away from the crust using the ratio, the outer core is 19cm away from the crust. The last layer is called the inner core, it is 6371km away from the crust.
