G9 Science Energy Transformation Project – Reflect and Share

How successful I was:

Completed making my vehicle on time

The vehicle shows a transfer of chemical potential energy to electrical energy

The vehicle can move forward with the motor powering it

Reflection

At first, when I made the car exactly the same as the precedent I found online, it didn’t work out quite well. The motor wouldn’t attach to the wheels with elastic bands, so I needed to find another way to connect them. Then I thought of making two holders hold the elastic band in place, one on the motor and the other on the stick connecting the wheels. After completing this happens, it was a successful way.

My car could have more Improvements because it is moving at such a slow speed and not going in a straight line but going a bit to the left. I suggest getting a more powerful motor next time or adding another one. The car works because it moves forward until I stop it. I made the car work and move using chemical/potential energy, turning it into electric power at the end; I was also familiar with soldering and successfully connected the circuit when it broke.

Before doing this project, I had never done soldering; to connect the battery, switch, and motor together, I needed to solder them. Throughout the project, I learned how to solder the circuit together and managed to do it by myself when I needed to solder items together.

 

Impact on the environment and potential client/consumer:

The car is not 100% recyclable because I used a battery to power the vehicle, so it would have some impact on the environment. I also used glue and plastic that is not recyclable and will all negatively impact the environment. It is an entertaining toy that could be bought by kids or adults interested in cars.

G9 Science Energy Transformation Project – Create and Improve

February 17th:

Gathered all the materials

Gluing the base of the car together (Cutting all the wood and stick to the correct size)

February 21st:

Soldered the electric circuit together and tried to connect with the car

Didn’t quite work, so I needed to change the design

Planned out a new design

February 23rd:

Built out new design, and it worked

The car moved very slowly, but you could see that it was working

February 27th:

Made some improvements to the car to make it go faster tried different kind of wheels, but all didn’t work as well, so I changed it back to the original one

Had some changes to how the motor was connected to the car

March 1st:
Finalizing the car and making some final changes

the car successfully goes on but still in a slow speed

Improvement and Feedback:

At first, I tried to copy the precedent I saw on youtube, but it didn’t quite work out as the rubber band wouldn’t attach the motor to the car, so I needed to think of another way to connect them. Then I thought of adding a holder on the motor and the vehicle to attach the elastic band on the scroll wheels to connect the engine and the car. It worked out quite nicely, but it also took me some time.

Then I let some classmates look at the car and give me feedback. Many of them were surprised at how the vehicle was spinning so quickly when away from the ground and moving so slowly on the floor, which gave me some thought to changing the car a bit. I needed to make the car weigh less as it is too heavy and has less energy to make it move quicker. I tried to reduce the weight of the car, I took off the wheels and tried several different kinds of wheels, but it all didn’t work out as well as the first one, so I attached the wheel back on, then I tried changing the battery to a newer battery, and it did help the car move a bit faster.

G9 Science Energy Transformation Project – Define and Inquire

We will make an energy transfer device in this science project in 2 weeks.

Ideas for making:

  • Perpetual motion device

Pros: Contains educational purpose,

Cons: Hard to build, complicated science concept, doesn’t theoretically work

Challenge: ☆☆☆☆☆/☆☆☆☆☆

Skills used: I might be using fusion for this project, gluing cardboard together and using a magnet that makes this device work

Precedents:

https://www.youtube.com/watch?v=7__4Kle7u7o

Audience: Anyone that is interested in perpetual motion devices

A video showing how to make a perpetual motion device could be an idea for me, but I might need to change where I put the magnet.

  • Elastic-propelled car

Pros: Easy to make, not time-consuming, Fun to play with

Cons: hard to make any change to the car

Challenge ☆☆/☆☆☆☆☆

Skills used: Using elastic bands, gluing wood together

Precedents:

Audience: Mainly kids because it is like a toy but it could also be for adult that just want to have fun and play with cars.

A good idea of how I can build a small car, similar idea to my project. Could be used as a model and add more ideas to modify the car and find ways to make the car go faster or be more efficient.

  • Windmill turbine generator

Pros: Concept is easy

Cons: Hard to light up the LED windmill to small can’t spin as fast when alone.

Challenge ☆☆☆/☆☆☆☆☆

Skill used: using battery and wires, making a circuit to light the LED

Precedents:

Audience: people who wants to light up a led light or people who are interested in different way to light-up LED’s

Video shows me a way to build a circuit to light up led light seems easy but could be hard to build by my self. They are using a larger fan to help the wind mill spin faster needs to find a way to make the windmill spin faster.

  • Electrical car

Pros: fun and entertaining

Cons: Attaching the motor to the wheels might be hard, soldering might be hard

Challenge: ☆☆☆/☆☆☆☆☆

Skill used: Soldering, making an electric circuit, gluing the car together, drilling

Precedents:

Audience: People at all age that wants to play with an electrical car or have fun with a small car.

The video gives me an idea of how to make the electrical car but might need to change where I place the motor and the materials I use to make the car.

Ocean Plastic Pollution

In my video, I talked about how ocean plastic pollution affects our and marine animals’ lives. There are many animals that consume and entangled in plastic every year, and we need to stop it. It’s kind of like our food chain small fishes consume plastic accidentally because they think it is food and then big fishes eat them and then bigger fishes eat them… and then, for example, a tuna eats the fish that consumed a fish that consumed plastic. and guess who eats tuna, us! So we should stop throwing plastic in the ocean and even reduce the amount of single use plastic we use.

Ocean plastic pollution

Ocean plastic pollution has become worse every year and if we don’t start thinking about reducing it, it will slowly lead to more dangerous problems. We learnt about Sustainable development goals (SDG) in this unit and ocean plastic waste is in it, this connects mostly to SDG #3,6 and 14.

This issue relates a lot to us because many of us eat seafood and plastic has killed and polluted a lot of animals, as many of them have consumed plastic. The chemicals in the plastic is also toxic to our body so we need to find a way to reduce the amount of plastic and not let this keep on happening.Re

Tierra Y Libertad

I’m Diego, I have died once in 1910 that was when my brother died but now I feel like I’m back alive and now I’m fighting for my right and most importantly to fight for my brothers will.

I think that the Mexican revolution was worth it because it bought social changes and political changes to the country. Before the revolution, the indigenous peasants were working for the rich landowners but now after the land reform happened they no longer need to work for the landowners. Even though a lot of people died during the revolution it still bought a good end to it, the lives of peasants are much better now. Even though the revolution have ended but there was still violence happening in Mexico. This revolution benefited the peasants a lot before the revolution they worked for the rich landowners but now they no longer have to work for landowners because the indigenous lands have now returned back to the indigenous people. Overall the Mexican revolution was worth it because it brought a lot of benefits to the people.

Fighting for Tierra Y Libertad

The Mexican Revolution took place between 1910 and 1920 and was a deadly struggle for land and rights. In this video, we’ll go over the details of the revolution and how it affected millions of people. Porfivirio Diaz, Francisco I. Madero, Victoriano Huerta, Venustiano Carrana, and Alvaro Obregon were the five presidents who came and went during the revolution. The Mexican Revolution lasted 10 Years and had a lot of assassination and distrust. Watch the video to learn more

Shackles From the deep

Shackles From the Deep by Michael h. Cottman is about discovering the path of a sunken slave ship and how throughout the story you can see that there is racism and discrimination is also happening to the African-Americans. You would also see some more detailed research about shackles and the story of Henrietta Marie. While Michael was on the trip to find out the story behind Henrietta Marie he met a lot of friends that helped him a lot in his further journey and what he did at the end.

I think that this book is very interesting and after you look through my notes below  you would know more about the central ideas and  the themes that I found.

The first central idea that I came up with was: Racism and Discrimination against black people and their history and you can see some of my ideas here.

As I read further in to the story I realized that there is a lot of places talking about rasicm and discrimination against black people but I saw another central idea: Tracing the path of The Henrietta Marie and answering some questions of the sunken slave ship.

Another place where I gathered all my ideas together is in lesson #9. So in this lesson we looked at Cause and Effect of things happening in this story which then connects into my central ideas.

When I was done doing all the pages above I think that I should add a bit more details and how they can all connect to each other so I pushed myself  to make another page about the connections and racism. In this book Michael wanted to really show us the detailed ideas of slave trade from Africa so he added a lot of ideas to support the one main idea is tracing the path of a sunken slave ship and how racism is also occured in here.

Thankyou for going through my post, The book Shackles From the Deep is a really good book so if you are interested please check it out.
