PE Reflection

In PE, we did a volleyball unit where we learned how to play volleyball. Next we had a dance unit where we chose a song and dance where we made a part of it so that we don’t copy completely from the dance. Right now we are on a unit about basketball which I personally don’t really like because I don’t really like basketball generally. I am hoping to start enjoying basketball soon.

Japanese Reflection

In Japanese, we are reading a story called Yamanashi. It is about a crab family talking about a legendary thing that used to be on earth. We also did the word checking where we find the meaning of a word and writing a example using the meaning of the word. We also drew a picture of the legendary thing that we thought what it was.

Drama Reflection

In this unit we learned about puppets and how to control them and make them look realistic. I learned that puppets need to have eyes and this is the main part of puppets. I also learned that when you want to show that puppets are speaking, they you need to push out the words. Puppets are very fun because you can do anythings you want with them. When you have a puppet that requires more than one person to operate it, you need to synchronise every part of the body or else the whole puppet looks unrealistic.

Science reflection

In science we are learning about waves right now. We learned about transverse waves and longitudinal waves. We also learned about eye parts and ear parts. I knew these things from last year, but I forgot it so this was a very good review. I also enjoyed it a lot which was good for me.

Music Reflection

In music I played the christmas song called jingle bells boogie. I was able to perform this piece in assembly. Now we are learning about the blues. We learned that they made their songs when they wanted to show how they felt and when they communicated.

Design Reflection

In design we made a new design for mascots with bad reputation. Some of my friends did Ronald Macdonald. I did the mascot for Burger King. I chose this mascot because he only had one expression that looked like he was going to kill someone any second. I made it so that he looks like a burger and so that it is cute. I learned that to make my design more friendly I should put a smile on the face. I also learned that these kinds of mascots need  to be round because it will not make it creepy.

Humanities Reflection

In humanities we learned about renaissance people and how they affected the world. I researched about Issac Newton. I made a comic of what Newton did with during his life. We also learned about how countries that gain control of other countries affected them. I researched about how Britain and Hong kong affected each other.

Math Unit Reflection

In this unit in math we concentrated in the pythagorus’s theorem. We learned how to find the hypothenuse of a right triangle. We learned the equation a^2+b^2=c^2. It wasn’t that complicated for me because I had already learned it at my house. It was a very good review for what I did and I also enjoyed it.

Conflict Materials

I am focusing on conflict materials in the smartphones that everyone uses in school. A lot of different companies produce these materials. Kids use them to call people, play games, and look at our schedules. Also, we sometimes use them as a stop watch. The cost of these phones differs by the number of gigabytes and the brand of the phone company.

There are a lot of materials used in smartphones, but I am going to explain about the gold (Au) used in the smartphones. The gold comes from Peru and Congo. In Congo, people are forced to mine these ores even though they barely get paid. The gold mined is used to coat wiring and make smartphone circuit connectors. Gold is a very good material for connecting circuits because it is a very good conductor. Gold allows electricity pass through wires efficiently, because it has low resistance. Gold is the 3rd best conducting metal, after silver and copper, with only 0.024Ω of resistance and it is also used because it doesn’t rust at all after coming in contact with air or water. Gold’s property is very stable. It doesn’t chemically react to practically anything which makes it very useful inside smartphones.

Regarding safety issues, a lot of people have died mining these materials. This is an issue because the military, which runs the Congo government, is not doing anything to reduce the death rate. They are just thinking about making money. They need to keep their workers safe because if they keep on killing people, they will end up with no workers left. Congo’s military makes millions of dollars using the money from selling minerals like gold. This is an issue because the military is getting a lot of the money, but only a little amount of the money is given to the workers. Ethically, people should not risk their lives mining for ore just for money. They should use machines that are not as dangerous and don’t put other people in danger. This is an issue because the military is using humans to make money, but not paying them that much. The people mining are not getting the right amount of money but they are risking their lives.

To help fix the problem, we could buy phones that do not contain materials that are mined from places like the Congo. If we do this, the companies which sell phones might stop receiving phones from factories that use materials causing problems. Instead, they will buy phones that are made from materials that are not mined from places such as Congo. Also, using materials that are brought in from slavery is illegal trade. We could also make Congo stop using slaves because if companies stop buying materials, Congo will not get any money and it would be just a waste of work done by the slaves. Also, another suggestion is people could protest against the companies and pressure them to stop importing the materials from places that use slaves to mine ores. Companies will notice what they were doing wrong and start using materials that are mined at legal and proper mines.
