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.
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 all! This is a draft for my blues solo summative.
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.
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.
Bb Major Scale + Thirds
Eb Major Scale + Thirds
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.
