Hi all! We recently had a unit in science about chemistry, and today I will do a reflection on everything I have taken away from it.

In the unit, we performed several experiments that caused physical or chemical changes, and we had to identify them. For example, we had a reaction where magnesium ribbon held under a flame for a while, and the flaming end produced a really big spark for a while.

Here is a video of the reaction:

I learnt that there is a very big difference between physical and chemical changes. I first thought that they were basically the same thing. However, most chemical changes are irreversible, which was pretty obvious but yet I didn’t really realise until now. I also got to witness some other reactions such as elephant toothpaste and some explosions which I, unfortunately, do not have video footage of due to safety reasons.

I also learnt a lot about density and about the separation techniques. I always imagined that a device similar to the Separation Funnel existed but I finally got to use one and the experience was pretty different from what I was expecting. I was expecting some colour-sensing technology and it would just pour until the sensor didn’t sense anything of that colour. However, it’s just by hand. There’s no fancy technology.

Here is a video of the separation funnel in action:

I also learnt about the evaporation technique, and I never knew about this technique. I had never even imagined separating saltwater. But after learning about this technique, it just made a lot of sense and it was pretty much all reliant on logic and math, which I already knew would be the case for physics, I didn’t expect chemistry to be similarly closely related to math.

Hello readers!

This post is a reflection of the Blues Solo Composition summative we recently did. This is similar to last year’s project, although this time we were accessed more strictly by accessing melody, rhythm, chords, articulations, etc. Mr O’Toole, one of our music teachers, gave us a solo he wrote, and we would try to match that and write our own solo using blues techniques that we learned with our Artist in Residence, Mr Reynolds.


This was a somewhat challenging process for me. I had been using MuseScore for half a year and had adapted to its controls and interface, so using Finale NotePad 2012 was giving me a headache already. It took me 15 minutes to realise that pickup bars were not in NotePad, and only in the normal Finale. I then started writing a simple melody which I developed further upon and repeating that same bar of melody some to create my solo. After receiving some feedback in class, I quickly realised that my solo was too dull due to the lack of articulations and dynamics. I quickly put those in and had another friend listen to it. He said that the melody was pretty good and the newly added articulations and dynamic changes spiced up the piece, however, it was repetitive (like I mentioned in my Crit C D reflection). However, at this time I figured that it was already time to leave it and just be done with it, the main idea of the repeating melody was kind of a mistake from the beginning, and it was hard to change it from that point.

Here is my solo.

Hi everybody! A while ago, we made some Christmas ornaments by pouring melted aluminium into clay molds that we made. We then calculated its surface area and volume to compare with our estimations. Here are my biggest takeaways from this project.

Working with Kids

Kids can change their mind very quickly. I was already in the works of producing a rocket when my kid said, “What about a present?”

I had to destroy my rocket and rebuild the mold all over again.


Estimation Techniques

I realised that the height of my present was different due to limited aluminium resources. My present was very short and I had to recalculate the height. That wasn’t a big issue though.



My present didn’t quite turn out the way I had anticipated it would. Essentially, one stripe of the pattern was completely missing, making it look really weird. The hole to hang the ornament wasn’t formed properly because my molding skills weren’t great. It was pretty annoying but interesting.

Hey there! This is a reflection of my coaster project. But what is the coaster project, you may ask?

The coaster project was a project to prepare us for the upcoming design summative which involves cutting out a table lamp using a Universal laser cutter. Using a coaster was just a practice round to get us ready for the skills we needed for the final project. I actually screwed up twice, once being that I left out the stroke on something and I actually needed that as fill, and another being that I forgot to upload the file…

Anyways, on we go! Here is the reflection!

What did you learn from this project?

Well, I learned not all that much. I am a digital innovator at CDNIS and I’ve already taken a very similar set of lessons, which gave me all the basic skills to do this. One thing I learned was that the black colour – which engraves – needs to be filled. I thought that the laser cutter just takes the image and processes it, but nope. Turns out it looks at the actual paths, and because the shape I was trying to engrave needed to be an actual shape, the cutter didn’t understand my coaster and it didn’t work.

Here’s my coaster. You might recognise this from the favicon I have for this website.

Hi all! These are the recordings of my music summative.

Hey, guys! Today I’m going to introduce to you the new Design unit. Basically, it’s linked to Humanities, and the final product will be a movie based on Hong Kong Heritage. My groupmates are Christine and Bella.

On Thursday, it was a Design Day. No classes, the standard stuff. We did a bit of practicing of making a movie, and we had to do it on CDNIS’s culture aspects. We got assigned Beliefs or Values, so we chose Values. We did it on Academic Honesty, which is an agreement that prevents students from cheating.

Anyway, here it is.

Now, obviously I have to do some sort of writing; we all know the drill. The question this time is…

What did Design teach you about teamwork?

Well, on Thursday, I learnt that we had to split roles sometimes. For example, we were filming students taking tests, and I was the cameraman. Later, I had to edit, so we split up and Christine and Bella went downstairs to film another scene. If we stuck together, we wouldn’t have been able to finish the video because there would be no one editing, or if everyone was editing, no one would film actual scenes.

Hey, everyone! It’s Rides1283blog here, and today I’m going to tell you about the amazing adventures I had when Lower School students were eating pancakes while wearing pajamas.

So, in Upper School, we need to do some sort of service to the community, and on November 16, I did exactly that with everyone else who went the Shek-O Beach.

We found a lot, and I mean A LOT for a small little shore like that. Just saying, we kind of went to a small little area instead of the real beach. Well, back to the main story.

We found a lot of styrofoam, bottles, cans, and containers there. We also found stuff we shouldn’t have even LOOKED at.IMG_5783

Here is an amazing photo of the early hours of the place.

Now, onto the real stuff.

I need to prove to the world that I did service. Here is a pledge and I will explain how I did it.

“I continually think about the impact of my actions to make positive changes to my personal behaviour and about the ways I contribute within my communities.”

Through this experience, I’ve seen a lot of rubbish on beaches, places where it shouldn’t be. And this pollutes the environment. BADLY. Think about where it’s coming from. It’s coming from the ocean. And why is that? Because all around the world, we’re using more and more plastic and therefore disposing more and more plastic. Well, we can stop this, and we need to all change how we do things.

Use reusable bottles, use reusable bags, put things in the garbage bin. All these small little things that everybody does, can help a little. Which is why I always think before I do something. I bring my water bottle everyday, and I don’t use plastic bottles. I have a reusable bag ready to use in my backpack all the time.

Hello, my fellow readers. Today I have this new class called Design. It’s super cool and it teaches us how to be a good designer. As the title says, we are using Illustrator once more! We made an Emoji.Design 1 Custom Emoji

Review of Emoji:

I think this Emoji is mainly well designed, as the outer and inner yellow/orange matches to make depth, and the dark brown for most facial features sticks out really well from the yellow. The eyes, having a gradient, creates a great feeling of 3D and I think the eyebrows are fine but a bit too classic and an overused eyebrow design. It’s also a very simple face, and easy to remember, but I think it’s a bit dull.

What I learnt:

I learnt what makes a good design as simple icons and memorable icons. Sure, more could be better, but you need to keep it simple, but not too simple that it doesn’t stick in anybody’s head.

Emoji Reflection:

In Design class, we had a way of reflecting very simply through Emojis. We would type in the Emoji or Emojis we felt during each activity, and that expresses our feelings.

Hai guis, it’s Rides1283blog here, and today I have this new Edmodo-like platform for upper school homework stuff. Oh my gosh, I’m becoming a mini-adult now! I’m almost in upper school! I can’t believe it. But that doesn’t mean I won’t be quickscoping people and rekting everybody, I’ll still confirm the Illuminati and be the most MLG blogger ever. So yeh, let’s get into it XDDDD.

We’re going to talk about what I learn about this new Moodle thing. It’s basically Edmodo, but there’s a forum, there’s new assignment stuff, and basically it connects through the whole upper school (I think.). I asked about the Day system instead of the week system and I got a few replies.

Moodle’s kind of fun because instead of a Hangouts message to Harriet, I can now use something like Moodle. Everyone can see it or add on to it.

And there’s the responsible use of technology agreement, which I found ordinary. You can’t cyber bully, you have to be respectful, you can’t use it inappropriately during class time, etc. There’s a list of games you can’t play, and I don’t have any of those, so I’m good.
