Math – Box and whisker diagrams

During the math class, we worked on “Box and whisker diagrams”. The task that we needed to do was choosing two cities and comparing temperatures. For the cities, I chose Tokyo and Sydney. I chose January, June, and December for the months and I worked in fahrenheit.

These are the screenshot of Tokyo and Sydney :

Screen Shot 2014-05-29 at 12.38.42 PMFor the January, Sydney’s min was 31.8 fahrenheit higher than Tokyo’s min, which is 65.6-33.8=31.8. Also, Sydney’s max was 31 fahrenheit higher than the Tokyo’s max, which is 66.9-35.9=31. Secondly, their medians were different, which is the middle date of the month(16). Sydney’s median was 32.3 fahrenheit higher, which is 66.4-34.1 = 32.3.

For the June, also Sydney’s min was 11.9 fahrenheit higher than Tokyo’s min, which is 47.8-35.9 = 11.9. However, Sydney’s max was lower than Tokyo because Sydney’s max is 51, and Tokyo’s max is 68.9. Therefore, I can know that Tokyo’s max is 17.9 fahrenheit higher than Sydney (68.9-51 = 17.9). Secondly for the medians, Tokyo’s median was higher than Sydney, which is 65.6-49.25 = 16.35

Lastly, for the december, Sydney’s min was 28.2 fahrenheit higher than Tokyo, which is 62.7-34.5 = 28.2. Also for max, Sydney was 23.6 fahrenheit higher than Tokyo, which is 66.6-43 = 23.6. For the medians, also Sydney was 26.15 fahrenheit higher than Tokyo, which is 64.7-38.55 = 26.15.

Technology – Minecraft Reflection

During technology class, we did minecraft for 12 weeks. Our unit was “fair game”, and we created a theme park as a group. There were four people in each group, and everyone had a role, which was leader, peace maker, creative person, or a follower.  I worked with Emily, Noel, and Jinho and our theme was “underwater”.

1. Use your product test to access your product / solution

Firstly, I think our group did pretty well for the theme, because we had lots of sea colours such as light blue and dark blue. Before making the underwater, we wrote colors to be the “essential” part. Secondly, we did not have any farm animals, as we said we “must not” include them. Third, I think our group did well on controlling the size of the structure.

Also, our group did pretty well for general work. We included lots of water, so visitors will be able to feel they are underwater. We also marked this as “essential”. However, I think our group have several things to improve. This is because it was good that we included lots of water, but there were lots of water in the corner(sides) that can make the visitors lose their ways.

Third, for the function, I think our group’s theme park(underwater) gives a unique and interesting feeling to creators, so our theme park will also attract other visitors. Also, in our theme park, people are able to walk and run faster. Therefore, functions work pretty well.

Fourthly, for the quality, our group divided our job equally, so everyone could build their structure well. Therefore, we did not make one person to do all the work, but there were still some members who spent more time than others.

Lastly, for the Aesthetics, I think it was the best one that we did on product / solution. This is because, our park attracts people with interesting colours and shapes as we wrote at “essential”. Also, our park gives a mysterious feeling, so it makes people wonder what is going to happen next. Lastly, our park has lots of colours so it is not colorless or boring as we wrote at “must not”.

2. How could your product/solution be improved?

First, for the theme, we used lots of different and colourful blocks, to include lots of colours such as blue, light blue, and white. Second, to control the size of our theme park, we divided our space equally. Therefore, our group’s structures are not too big, but not too small. However, there are still things to improve. It is our group did not have any sea animals.

Second, for the general, we included lots of water blocks to allow visitors to see water. For my water slide, I made water to flow. Also, our group included water block on the sides, to make visitors able to see water. Our group included glowing blocks to add brightness. However, I think we should include more glowing blocks, because our theme park looks a little bit dark.

Third, for the function, our group built speed “command blocks”, so it made people to walk and run faster. Also, our theme park gives a unique feeling by colourful colours and interesting shapes.

Fourthly, for the quality, we could finish our own structure by lots of time and efforts. We worked at home if we could not finish our structure during the class. Therefore, everyone could finish their own structure really well. I felt really proud when our group theme park was completed by our efforts.

Lastly, for the Aesthetics, our theme park looks attractive, because we included unique shapes and colourful blocks, as we wrote at “essential”. It gives a mysterious feeling because it was located underwater. Therefore, I think we could improve aesthetics by unique structures.

3. Design Cycle


In this unit, we started with investigation, which is the very beginning of the process. For investigation, we started with “small group discussion”. During the small group discussion, we discussed several things, such as pros and cons of working alone and collaboratively, our responsibilities, and differences between online and offline cooperation. Secondly, we talked about minecraft and discussed how to use minecraft. Next, we chose a theme by drawing lots(straws), and our group’s theme was underwater. We brainstormed things that are related to underwater, and everyone could chose a structure that we were going to build. I chose water slide, because I thought it would be interesting if water slide would be placed underwater. Third, our group looked for reference images and videos, and got ideas from those resources. After looking for resources, I determined to build water slide with a steep slope, to make water flow easily. After that, we moved to “design specifications”. We wrote the things that we must do, the things that we have to do, the things that we must not do. I think I did pretty well on investigation, because I looked many reference images, which helped me to build water slide more easily. Also, I tried to listen to our teammates’ opinions, but I think I should have given more ideas and stated my opinion to improve the investigation.


For design, each group drew three maps. Emily and I created one map together, Jinho drew his map individually, and also Noel drew the map by himself. After that, our group discussed about pros and cons of each map, and we could finally choose the final map after a long discussion. For our final map, we chose to make four structures to be located in every corner. Also, our group said, we are going to make people to move without transportation. Instead of transportation, our group said we are going to put command block, which can make people to run and walk much faster. I think the thing that I could improve was details for the map, because the map could not fully show the design of the maze to other people.


During the plan cycle, we wrote every step, description(role), resource needed, and time needed for our structure. After writing this, we got feedbacks by different people such as the things that I need to improve on plan. After getting feedbacks, we fixed our plan with more detailed. The thing that I need to improve on my plan was making it more specific. It is because, my first plan did not have enough details. Therefore, it seemed that it would not be able to follow steps well. Therefore, with the feedbacks, I fixed my plan in more specific way, and this plan made me easier to create the water slide.


Finally, after finishing investigation, design, and plan, we started to create our theme park. To begin with, Noel dug a big hole to make spaces to build. Secondly, we started to build our structure, and wrote what we accomplished today. While creating my water slide, I changed the plan a little bit, because I could not plan to make an entrance before. It was challenging because I was not really good at using minecraft. However, I asked my group members, and they helped me a lot.  With their help, I could improve my water slide. I think I have several things to improve on my water slide. First of all, I should have made the entrance more interesting, so it will attract more people. Second, I think I should have made a longer slope because my water slide looks a little short and small.

Japanese music

1. Japanese music

During the music class, we learned about Asian music. Our unit question was “What makes music sound like it belongs to a particular part of the music?”. One of the activities that we need to do was creating own Japanese music. The song had to be 16 measures, using two Japanese techniques, and using pentatonic scale.

I used insen for pentatonic scale, which is C, D♭, F, G, B♭, and C. For the Japanese techniques, there are several techniques such as Shan, Kororin, Sha sha, Ato Oshi, and we had to choose 2 techniques from them. I used Shan and Kororin. Shan is a technique when  two notes are played together, and Kororin is when notes are played in different rhythms.

For me, it was a little bit difficult to create Japanese music, because I was not used to create a song with the Japanese techniques. However, finally I could finish this after lots of thoughts and trials.

2. Comparing Chinese, Japanese, and western music

The second activity that we need to do was writing several paragraphs of the differences and similarities between western, Japanese, and Chinese music instruments. After listening those music, I could realize that there are several differences and similarities.

First of all, for the differences, I could realize that Chinese music has more trembling sound than western music and Japanese. The second thing that I notice was Japanese and Chinese music has different techniques. In western music, there were more variety of techniques, such as staccato. The last thing that I notice was Japanese, Chinese, and western music use different instruments to play music, and those instruments has different number of strings. For the similarities, I knew that some of the Chinese and Japanese instruments are made by bamboos.
