Weekly blog post Jan 26

Hi everybody! It’s been a long time since I last wrote a post but I am back! This week was a week that was very interesting because I did 2 science experiments.

So on Monday, I started in experiment where we would put a bread with vinegar and observe the bread. I also re-did the borax experiment.

On Tuesday, I had sports day and I got last place everywhere. My class did well in the class events.

On Wednesday, I had the four experiments which I wrote a post on and I also had my 3rd VA and fourth coding lesson.

On Thursday, I observed my crystals after some waiting and once again, crystals formed at the bottom and not on the pencil. I stirred the Borax, what else could I have done?

And today, I observed my bread and I also did a few math questions.

Science Experiments

Today, I had the privilege of having the chance of having the experience to do 4 exciting experiments. he purpose of these 4 experiments was to differentiate the difference between a physical change and a chemical change. The four experiments that I conducted with my group were: mixing liquids(the jar containing the liquid is at the top),observing a candle burn, squishing marshmallows with a syringe and mixing vinegar and milk.

Firstly, I did an experiment where you mixed many liquids together. The few liquids were: water, food colouring ,vegetable oil and honey. My group mixed the 4 liquids together and after 15 minutes of waiting, there were 3 layers of liquid. The first layer at the top consisted of oil. The second consisted of water and food colouring mixed together. And the third layer consisted of the honey. The result if the change was a physical or chemical was very interesting. I decided on both as you could separate the honey and the oil. But you could not separate the water from the food colouring.

Secondly, I observed a candle burn. For some reason, the flame smelled sour for some reason. I found this very interesting as fire burning wax smells very smelly. The answer if the changes were physical or chemical was both again. The reason because the wax can be restored into it’s original form but the wick cannot.

Thirdly, we squished marshmallows to see if after squishing the marshmallows, the marshmallows would become different. The answer was simply a no. The marshmallow just shrank in size and became shrivelled. That’s all. No changes in properties or whatsoever.

The final experiment consisted of mixing milk and vinegar together. Before the experiment it was predicted that the change would be chemical and it turned out right. After mixing the substances together, a very unusual combination occurred. The substance turned out to be white taking on the colour of milk but smelled sour like vinegar. The change was of course a chemical reaction as you cannot reverse the mixture.

Today I learned a lot about physical and chemical changes after these four experiments. I believe that my knowledge in science has broadened thanks to this day. Thanks for staying in touch and once again please leave a comment below if you liked this post or not. I’d love to hear from you! Until next time! Bye!


Borax Experiment

Today, I finished the science experiment of making borax crystals during class. I put some borax washing powder with boiling water and had a pipe cleaner hung to a popsicle stick inside a jar.

I really enjoyed this experiment although I did not get the desired results at the end. I was a bit disappointed that my crystals only formed at the bottom of the jar but not on the pipe cleaner. I should have mixed the borax more thoroughly with the water to have gotten more crystals on the pipe cleaner.

I found that my classmates had more crystals as they had their pipe cleaner twisted into many shapes that would hold all the crystals and that they stirred the borax more thoroughly than I did.

I have already finished the whole experiment and I am planning for my next experiment which will be the same as this one but I will be changing one variable. I would like to add paper to my experiment.

I learned a lot of things from this experiment but I could not draw 100% conclusions as we are doing it again with paper but one thing’s for sure I really enjoyed this activity and I learned new stuff about chemical reactions.

Camp is finally here!

Hello everyone! It’s me again, and today I will be talking about my camp experience at OuImage result for outward bound hong kongtward Bound Hong Kong. I had a wonderful experience at Outward Bound this year. I arrived at camp on Tuesday and I left camp on Friday.

So on Tuesday, I got to know my group members and have a camp brief by my coaches. I then had lunch that was made by Outward Bound’s chefs and it was very delicious!  I then put my clothes in a barrel that will be transported to my campsite as I camped on the first 2 nights of the 4 days and 3 nights program.  After lunch, I did an activity called ‘The Beam’. It was pretty fun and I had to work as a team to be able to overcome the challenges.  I then took the bus to my campsite.

At the campsite, we learned how to pitch our tents and made our dinner. For dinner, we had to cook food ourselves as we were given cooking utensils and food material to cook. I made curry for dinner that was way too spicy and some white rice. After eating dinner, we made a campfire and we roasted marshmallows! I then went to bed in my sleeping bag and fell asleep very quickly.

The next morning, I woke to the sound of the birds and crickets. I brushed my teeth and did a morning exercise with my coach. I then, as a team cracked a code that involved teamwork and some intelligence. I, unfortunately, got hurt during the activity. I then build a natural shelter with my group by using leaves and twigs. I then had lunch that was a sandwich with cheese and ham on the cob. I found the sandwich that I made very delicious. I then began on a hike. I then had a dinner made of rice with vegetables.  I then roasted marshmallows with my friends and I went to bed.  As I lay in bed, I realized that it was my last my night in the tent. I felt a bit sad as I wasn’t allowed to have more fun at the campsite. As I closed my eyes, I felt that I was satisfied with my work done on the 2 days done on the campsite.

I woke to the sound of the birds and the smell of fresh air. I got changed and I after breakfast that consisted of some bread, walked away from the campsite. Unlucky me, my group was not given the privilege to be able to take the bus to Outward Bound base. When we arrived at the base, we went to try the ‘High Elements challenge’. We donned the helmets and climbed the rope to the top. I then went to have lunch and I went to see my dorms. I then got changed into my swimsuit and went to go kayaking with my group. Before I kayaked, I had to do float test which went well.

I then went into the kayaks and kayaked around the base. We went kayaked to the ‘Jetty Jump’ area where you have to jump from 6 metres above the water. I without really thinking jumped into the water and I found it very fun!

After doing the jump, I went back to my dorm to take my first shower in 3 days. I felt incredibly good when the water touched my skin. I then had my final dinner at Outward Bound. I found the food really good. I also felt a bit sad as everything had to end so quickly. I was sad to go to bed that night as I really enjoyed the program really much and would have wanted to stay longer. I then had a de-brief with my group and my instructors. I went to bed a bit sad as I had to leave.

The next morning, my team sealed off a whole 4 days of hard work by completing the final challenge. I then got to share my feelings on the camp. I also shared I had learned and tried many new things. We went to the assembling place to have a closing ceremony. I received my certificate of participation. I then got my lunch of sandwiches and Outward still delivered quality food even when making the simplest things. I said goodbye to my coaches and to the place.

In a nutshell, I had a wonderful experience at Outward Bound. I would like to go to Outward bound once more and have an experience like this once more. I feel a lot tougher after this experience and I learned how to be independent. One thing I particularly enjoyed was cooking. I believe that cooking was a very meaningful experience as I always have my food cooked for me and I always take things for granted. I believe that by cooking I realize how much work my nannies need to pay to make the food I happily eat every day.

All in all, this has been a life-changing experience where I learned a lot. I will cherish these memories and I am sure I went out of my comfort zone and made into my ‘outward bound’. I will never forget this experience and I will remember this event dearly in my memories. This event will be something I will be able to tell my grandchildren about grade 6. I hope you enjoyed this blog post and I hope you will want to visit Outward Bound Hong Kong sometime soon. It is a great place to be.


17 nov weekly reflection

Hello again!!! Once again, sharing what I did this week in this weeks’ weekly reflection with you all. This week marked 2 achievements. I received second place in both a singing competition and the Hong Kong National Blitz Chess Championship.

So back to business! On Monday I did a few Math quizzes on That Quiz which I found fairly simple. Today we also did a class discussion on what is economy and all about economics.

On Tuesday, we watched a slide show sent to Ms. Sandul which I found helpful as the slideshow increased my knowledge on economics and the economy. Today we also started to make a prototype out of a box(there is a full report on my prototype). I also went to Mr. Mark’s classroom to have briefing of my field trip on Friday.

On Wednesday, I finished an end of unit Math test which to me was fairly simple. I also did a presentation of my group’s prototype to the class(full report in another post). We also learned about the 4 ways of reading. We also inquired into how to use quotation marks. I was split into a group which would enquire on on era. I am enquiring on the economy of the Song Dynasty.

On Thursday, sadly I skipped school to have my singing competition where I came as the first runner-up.

Finally on Friday, I had a field trip to Stanley Beach where I found many problems on the beach. For example, I found some dead fish and the life guards were texting messages on their phone. On Friday, I further inquired into my era’s economy.

When do the prototype making stop???

Today, we finished another prototype! Our prototype is called the Fluffy Case! Here is a picture of it.

My group decided to make a case after a lot of people have had there things going missing and that they always break there stationery. Inside our prototype, there is a bit of yarn stuck to it that will help protect the stationery. It can be used to store anything that is small enough to fit it.

Our prototype has been decorated with glitter and is made entirely from recycled materials. It has been mostly made of an old headphone box. Special thanks to Mr. Larson for giving us the boxes!!!

Sorry!!! The photo will be up here soon!

10 Nov weekly reflection

Today we had the Remembrance Day Assembly and I sang for the school as I was one of the Treble Timbertones so I had to sing to whole school which was very fun. So back to the week…

So on Monday, We started a New Unit! The new unit is Where We Are In Place and Time. I had my final range lesson for golf which was pretty sad as I really liked golf lessons. We also had a dance class which our dance group decided on what kind of music to dance with. We also researched some articles that would be shared in class on Tuesday.

On Tuesday we shared our articles in small groups. My article was chosen by my group and we prepared for our presentation of our article that would happen on Wednesday.

On Wednesday, I presented my article to the class and I realized that I should have allowed some of my group to speak more. My class also went to the green roof and we read books to our reading buddies. I did not have the afternoon as I left early as I had a music singing exam.

On Thursday, we watched a video that was an explanation of Remembrance Day which was pretty emotional  to watch.

Today as explained earlier I sang in the Remembrance Day Assembly. This was the first time I performed with the Timbertones. I shared my parent’s money budget with the class with my findings. I then had my Chinese lesson, and then I had an interview right after lunch from a man who was going to write an article on our prototypes.



Design Thinking Model of our prototype

This week, we added our final touches to our prototype and we finished the design thinking model.

Here it is:

The Cooling AC (Design Thinking Model)

By: Ava Helbig, Annabelle Au, Cheng Hsin and Siena Mulchand



People who are poor and don’t have an AC can use this because our bottle project is made to make the inside of a room cooler during the summer.



The weather is hot during the summer time, so we wanted to help people who couldn’t afford AC.



Before we decided to do this project, we came up with other ideas.

  • A Fan
  • Windmill
  • A swing set that powers an AC
  • Annabelle’s hamster that runs on the wheel and powers the AC



Energy Used:

  • Wind Energy (to go through the bottles)
  • Kinetic (the air moving through the bottles)
  • Mechanical (When the air reached it’s target; AKA the room)



When we tested our prototype, we used a thermometer made from little bits from the innovation lab to sense the difference of temperature in a room. We also tested our prototype with students in the classroom. We made a chart to organize all the locations that we have tested the Cooling AC in. We tested the prototype in places like the gym, the playground and even the cafeteria.

How it works:

The hot air goes through the bottle and the bottle neck compresses the air and makes it cooler. It is not such a significant change because the smaller it is the less air compressed but it works. We have touched the inside of the bottleneck and figured out that it is cold so we think that is what makes the air cold.

I hoped you liked it! This the work my group did throughout the whole of 3 weeks.

Robotics 20/9/17

“I am a Robot! Is my name C-3P0, R2-D2 or Dancing Cookie Robot?”


Today we had robotics class during the third and fourth period. We further developed our codes to help our robot follow a line and avoid an obstacle.

This the code I first came up with. I had high hopes for but it failed. The problem about it was that it was short and that I was trying to find the easy way out.


This is the code that I came up after some time in my ‘thinking tank’. I took my bot to the track and tested but yet after some good hard work I had failed. I here consulted Ms. Fung ( the robotics teacher) and she told me that I had the right idea but I had to combine the two codes into one code.



Not even did Ms. Fung tell me that I had to combine the 2 codes she even taught me how to combine the two codes. Here is my final code.

Try my code out and I wish you luck!!!


I have a special ANNOUNCEMENT!!!

Hello, all! It’s me over here and I am super stoked to tell you that I have an announcement!

I will be starting a scheme on my blog which includes strategies to be happier, how to be mindful,  positive ideas and much more! I will be posting a blog post like that once every week!

You might be asking yourselves why would I start this scheme. I believe that by starting this scheme I can make a lot of people happier and that I can attract more people to my blog. I will be posting my blog post later and I really hope that you will enjoy it.

I am very excited to be starting this new scheme and I hope that you will all enjoy this new scheme.
