In the process of my painting, I used 5 techniques:

– scumbling

-lining

– highlights and shadows

-texturing

– spattering

1. Scumbling

This is a technique to create the background/bottom layer of the brick wall; we used three colors: brown, red and yellow. By using scumbling, I can create a more realistic wall because the colours are distributed evenly and naturally, so that each brick looks different.

2. Lining

Lining is a technique to line out the basic shape of the brick wall. We used some straps of wood to measure the distribution of the bricks, so that the bricks are similar in size

3. Highlights and shadows

It creates a 3-dimensional view of the brick wall. We chose a direction the light source is coming from; we used this as the reference and drew the  highlights and shadows.

4. Texturing

Not only the borders of the brick has to have lights and shadows, the  brick also needs shadows. Texturing uses dark paint mixed with water to create a thin layer of shadow. By texturing the bricks, the wall now looks more realistic

5. Spattering

Spattering gives the brick wall more diverse elements, the light colors contrasts with the dark paint wall, creating a richer scene.

Things I did:

1. I collected the materials I need for the circuits

• batteries–these two batteries are 1.2 volts each, the energy collected will be stored in the batteries
• solar panel–the solar panel used to collect the energy, it is around 5 volts
• breadboard–the breadboard is a perfect choice to test my circuits and check if they work quickly before finalizing my work
• alligator clips–connect the components together
• switches–so that I can control when the solar panel is charging the batteries and of course control the motor
• motor–spins the Ferris wheel
• LED lights–work as diodes

2. I tested the voltage and the positive pole & negative pole of the solar panel and the batteries with the multimeter

• the voltage of the solar panel is around 5, the voltage of the batteries is 1.2
• If the voltage of the solar panel is lower than the voltage of the batteries, the batteries will transfer energy back to the solar panel, which can break the circuit
  • to prevent this situation, I need to add diodes in my circuit, such as LED lights
• Using the multimeter, I found out the positive and negative poles of the solar panel and the motor.

3. I tested some components of the whole circuit

• I managed to power the motor and connect a switch to it

Things I need to work on:

1. learn more about circuits, watch Youtube videos and ask the teachers
2. Connect the components together by combining them using the breadboard by the next class
3. start making the base of my Ferris wheel

25 Feb & 1 Mar 2022:

Things I did:

1. learned how to build the circuit with Mr. Michie

• a LED light was placed in the middle
  • prevents current from flowing back
  • it tells us if the solar panels are charging the batteries
• a switch is placed between the solar panel and the batteries
  • the batteries can be damaged once it is overcharged
  • the switch can control whether the solar panel is powering the batteries

2. Finalized measurements of the base and started collecting materials

Things I need to work on:

1. the motor was spinning too fast, do research on how to slow down my motor
2. transport the whole circuit onto a circuit board, ask Mr. Michie

3 & 7 Mar 2022:

Things I did:

1. soldering

• diode
  • In my previous testing circuits, the LED lights worked as the diode, therefore, when the light is shining, I can interpret that the circuit is working. However, the diode can not light up, I am not able to figure out whether the circuit is working.
  • After asking Mr. Michie, I solved this problem by using the multimeter, Testing if there is electricity flowing through the wires can help us find out if the circuits are working.
• electric tape
  • If the metal part of the wires touch, it can cause a short circuit
  • using electric tape can prevent the short circuit from happening

2. made a wheel for my model

Things I need to work on:

• decorating my project
• finish making the ferris wheel

Reflect and Share

Things that worked well:

• The soldering process worked out quite well, it stables the wires very well and keeps my circuits organized
• The Ferris wheel is a good choice to make, it has a simple shape and it is recognizable, the materials required to make it is also very easy to find

Takeaways:

• In the process of this project, I developed a lot of new skills. I learned more about circuits and soldering. Before this project, I did not have any experience on circuits, but as I learned how to make my project by looking at YouTube videos and learning from teachers, I was able to make a toy that transfers energy by myself
• My peers gave me a lot of help. They were very supportive and gave me a lot of suggestions. also, I was able to work on my project with others that are doing the same thing, so that we can learn from one another

Things to Improve:

• Planning is the most important aspect that I need to work on. At the end of the project, I was not able to finish the Ferris wheel. In the first few lessons, I spent most of my time testing the circuit. Therefore, the time to do the artwork in my project decreased, and I was not able to make the gondolas. Next time, I need to make a timeline, to better track my work
• There were also acre technical issues in my project. The motor was still too fast. There are many ways to slow down the motor; I chose the easiest one, by adding weight to the Ferris wheel. However, this is also the less efficient way. I was not able to make a system that can efficiently slow down my motor since I did not have enough time.

Our last project is to decorate a door for Ms Yu using Chinese style elements.

My biggest success was we finished the door decoration on time but if we had more we could make it more delicate. Skills that I learned or developed were  how to organize my work better, so we could gain more time. If I did this again, one thing I would do differently is to use rich designs. One piece of advice I would give a future student doing this project is not to think things so difficult, you won’t have time to finish it.Overall, I think this product was successful because we finished it.

This is our door decoration and our design sketches.

            In the past few years, governments have struggled to ban single-use plastic. Banning single-use plastic is not an effective way to save our oceans since it is not the only problem of plastic polluting the sea and people might use other materials to replace plastic which will pollute our sea even more. Some who disagree would say single-use plastic are killing our marine life. However, the problem is not plastic, it is the people.

           Banning single-use plastic is not an effective way to save our oceans because it is not the only problem. A research by the United  Nations Joint Group shows that land-base sources account for up to 80% of worlds marine pollution, 60 to 95 percent is caused by single-use plastic . This shows that only 28% of marine pollution is caused by single-use plastic.  Marine pollution is also caused by plastic products and rubbish. Banning single-use plastic might help a bit but it doesn’t improve our ocean quality, only stopping it from getting worse. If people only ban single-use plastic, the situation just goes on. Therefore, banning single-use plastic is not an effective way to save our oceans since it is not the only reason causing marine pollution.

          Banning single-use plastic is not an effective way to save our oceans because people might use other materials to replace plastic which pollutes our ocean even more. For example, the city of San Francisco has banned plastic bags and sold people paper bags and recycled bags. ( abc7 news)Since recycled bags are not fully implemented, only a few shops sold them so people usually use paper bags. However, a study by the US Environmental Protection Agency, paper bags generate 70% more air pollutants and 50 times more water pollutants than single-use plastic. This is because four times as much energy is required to produce it and 85 times more energy to recycle it.This demonstrates that the materials that people use to replace plastic often harms our environment more by releasing the pollutants into oceans and the air. Also, governments had to spent more money on recycling paper and recycled bags. If using other materials pollutes our ocean and environment even more, we should use the convenient plastic.Therefore, banning single-use plastic is not an effective way to save our oceans because people find ways to replace it.

            Opponents might argue that single-use plastic harms our marine life so bags should be banned. According to a recent research by the National Geographic, 700 species of animals have been reported – so far – to have eaten or ensured in plastic.  Even though animals sometimes mistake plastic for food, the problem is not plastic, it is the people.( merchant, Ami Ndioye ) Firstly, animals were often ensured by plastic that were blown into the sea. If people throw the plastic bags into the rubbish bins, the lighter plastics such as single-use plastic will not be blown to the sea and the animals won’t get ensured. Secondly, the marine animals are more often ensured by fishing nets, not plastic that human on land use.Therefore, banning single-use plastic is not an effective way to save our oceans because plastic pollution is often affected by human responsibility.

Overall, banning single-use plastic is not an effective way to save our oceans because it is not the only problem of plastic polluting the sea and people might use other materials to replace it. Even though some people say single-use plastic harms our marine life, it is the problem of human, not plastic. Also, banning single use plastic might lead to other major issues

After making the product, We did a reflection sheet.

My biggest success was painting the phone case but I shouldn’t paint the back of the box because the back might not be straight. A skill that I developed is my cutting skills because if I wanted to paint, I have to cut the shape of the cat very carefully so it’s quite hard for me. If I do this product ‘
again, I would probably cut out two holes for the magnets so it won’t be so thick.

Nowadays people spend a lot of time on cellphones, even students. They are always using phones and seldom connect with the community or the nature.Therefore, I made a devise for stopping people to always use cellphones.

design the game sheet

The picture on the left side is my final product. It is a box with a lock on it, You can lock your phone in it.To open the  lock  you  have  to  play a game and find out the color password so that you could  get your phone  back. This game  needs  two person to finish it, in the process, people can communicate  more  with  each  other.

But I think the product id not so good- looking as last time, so I wish I could improve this. I also used a lot of tilme to make the product and doesn’t have time to find a partner to judge my work.
