3D Printing & Laser Cutting

Today, Mr Larson, a teacher from the IT Department did a presentation on 3D printing and laser cutting. We had to answer 2 questions: “How 3D printing affected the world?” and “How laser cutting affected the world?”

3D printing makes life much easier. It makes building buildings much easier. You can simply design a house and upload the design to the printers. It also helps people with disabilities, for example, you can make prosthetic arms for people missing arms. It would also encourage people to become entrepreneurs, for we can design 3D models and sell it to others or simply sell printed objects.

As for laser cutting, it would make it easier and cheaper when cutting things such as glass, metal or wood. It also makes the cuttings more accurate and less dangerous, for there is usually a case around the machine. However, the laser cutter releases toxic fumes but using an air filter changes that.

Sports Day

On Tuesday, 23 January is Sports Day! Me, as a Grade 6 student, had to do the running first. I ran in the 4hundreds. When the whistle blew, I started running, I passed more and more people. In the last 50 meters, I ran faster and faster until I was around the fifth as I passed the finish line. Although I only ran about fifth in my group, I was still happy with my result.

After running, we started playing other games, for example, “Capture the Flag”, long jump, and throwing.

I had lots of fun, although I learnt about “practice makes perfect”. I should really prepare for sports day next time.

Borax Crystals

My Crystals

During 15th & 16th, my class worked on a science experiment-making crystals!

In the whole experiment, we used Borax, a glass jar, a pipe cleaner, hot water, and two popsicle sticks. First, we scooped 2 tablespoons of Borax into a glass jar, then poured in hot water. Then, we stirred the mixture with a popsicle stick. After that, we had to attach a pipe cleaner onto a popsicle stick. Put it in the glass jar. Make sure the pipe cleaner does not touch the bottom of the jar. Then wait…

After almost 24 hours, we examined our jar. Mine had lots of crystals. They were small in size. My crystals were mostly on the side of the jar instead of on the pipe cleaner. One of my friends did not get many crystals, but the crystals were very large. I am wondering why this happens. Could it be the size of the jar, or is it because of the amount of Borax and water you got, or how well you mix the Borax and water.

In a week, we will do this experiment again, but we have to change one variable to observe the difference.


Yesterday, 29 January, we had a third experiment. This time I used magnesium sulfate (Epsom salt) and lots of crystals formed (in the left of the picture above)! Shame I couldn’t get the pipe cleaner out. Before that, I also used table salt but added to little (2 tablespoons) so it did not saturate and crystals did not form (in the middle of the picture above).

Weekly Post November 5 – 11

This week, we started a new unit in UOI – Where We Are in Place and Time.

On Monday, we did a pre-assessment on the new UOI unit, and also, in Maths started working on decimals. I found out that working on decimals is harder than I thought.

Tuesday: Today, we compared our old journals and thought of what we could do better. We worked on money and budgets for Maths.

On Wednesday, we presented a presentation about a newspaper article we worked on yesterday. I went up to the Green Roof for the first time and read books as well as played with our buddies. The morning class’s students were easier to interact with than the afternoon class’s children.

On Thursday, we worked on the Central Idea of the unit.

Thank god it’s Friday! Today, we worked on Maslow’s Hierarchy of Needs.

This week is not very busy, but we never know, maybe we’ll have to sleep at 10:00 in the next week!

Where We Are In Place And Time

Where We Are In Place And Time is a UOI unit. We have just started it and had to write a blog post about what we know.

This unit is mostly about economics, something I am not very familiar with. I know that the stock market is related to trading things. Here, production and consumption are very important. Also, money is only a way to calculate how much you have.  There are lots of ways to buy things, like cash, credit card, Octopus Card, etc.

This is all I know. I am looking forward to this unit.

Solar-Powered Electric Car

In an IB school, there are 6 units in UOI. My class has just finished How We Organize Ourselves, a unit in Unit Of Inquiry. In every unit, we all have to write a summative, just like this time, but we also have to make a prototype.

We had to create an object that can harnesses, stores and distributes energy as our summative.

Me and my group were not always focusing, and took a few days to finally think of and agree on making an electric car that uses sun’s energy.

Despite the fact that we could work very fast, we were still behind, mostly because we did not plan. We soon came up with a good method of doing it and started to have much progress.

I learnt that we should always collaborate and communicate when doing teamwork and that we should always have a plan first.

4th Week of Class

Hello again! We have just started writing weekly posts.

This week, we have just started “Book Club”. I had chose a Morris Gleitzman book. During our “Book Club” meeting, we also had a party to celebrate our Assembly (Please see blog post “Medieval Fair”). 

We brought some food to school to celebrate

We also did the MAP test. It was a bit hard in a few parts. It was an awesome but tough week. Please read on for a more detailed review.

We did the MAP testing during the week. I found the Language test a b it hard, but I think my result will be alright. Me myself is very excited to know the results of the test. Ms Lee also came in to teach us about the brain.

In Maths, we learnt about Algebra and patterns. I found Algebra quite easy except a worksheet with an unknown number on both sides of the equation. I also found our patterns’ worksheets quite easy. I was a bit careless so I got some easy questions incorrect.

In UOI (Unit Of Inquiry), we focused on self-awareness. It was very hard for me because I wasn’t very self-aware before. It took me a while to finish the homework, reflections and even the worksheets so please don’t blame me if my blog posts aren’t very good. I found out that my time management skills weren’t very good. I should really work on these.

In Literacy, we worked on writing memoirs. As said, I’m not very self-aware and couldn’t think of anything to write.

To tell the truth, it was very hard to write this post, and I’m quite sure that this piece
