I predicted even before the EE day that there will be a lot of different problems arise from my EE experiment. And that’s exactly what happened today. First of all, my original method involves using a burette. However, it’s really difficult to measure the temperature of the water drops exactly. Since it’s a long narrow tube, it’s difficult to assume that the water on the top of the burette has the same temperature as the water dripping out of the burette. Then, after taking some tour to the different science department, I was casually introduced to using a shorter-length and bigger-width syringe instead. And I realise that it can solve my problems better. Now, the liquid can be mixed together equally, the top can be closed by a stopper, and the syringe can be wrapped around with aluminium foil to reduce heat loss. Hence, one problem solved.
Then, I decided to do a preliminary trial to find the correction factor “f” as well as finding the surface tension of water at other different temperature instead of the room temperature. I used a “water drop counter” in this experiment, it will tell me precisely the volume of each water drop. However, there is a bit of a technical problem, since I’ve never used this kind of equipment before. Due to time constraint and trust issues, I decided to try to do the experiment manually. However, after I get the value for the surface tension of water at 60 Celsius and compare it to the literature value, I realise that the value I found is close to the real value but it’s also close to the other surface tension values of the other temperature (e.g. it’s also close to the value of the water at 40 Celsius), too. The error bar is too big that it overlaps with the value of the other independent variable.
Then, I realise that I shall change my equipment to more precision ones. That’s when I decided to measure the volume of the water drops using a precision mass balance to 3 decimal places and count the water drops to 50 instead. Then, I set up the whole experiment at the back of the science class so to prepare for the next time I came, so that I just have to conduct the experiment and record the results directly.
I’m writing my EE in physics on the relationship between the temperature change and the surface tension of water. I plan to work out the value of the surface tension by using the Tate’s Law. What I found difficult is that the original Tate’s Law doesn’t have the variable (f) in its equation, however only later that this variable is introduced into the equation. Originally, this is a characteristic value given to the stalagmometer, an equipment used to measure the surface tension. However, I’m not using this equipment, I’m using a simple burette, and I need to find the value “f” for this. I can’t just search up the literature value for this since burettes are not usually used for this Tate’s equation. Hence, this has been stressful during the research process. So, my plan is to do more research on this, and if I am stuck, I shall approach my EE supervisor for advice and move on from that.
Hello everyone! I am very glad that I got chosen to be part of the facilitators’ team to lead an IFP conference that will be based in Maesot. Currently, we are divided into several groups planning the actual activities on each day in the conference itself. And I, with another person from East, and with 4 other people from Dover, are planning activities on the theme of “Making a Change”.
First of all, let’s talk about the whole group atmosphere. I don’t want to be frank, but since this is my reflection post and about my opinions only, I think I shall be honest with myself in this writing as I am in my head. In the past, there is from time to time, at the back of my head, where I felt like this is not an authentic experience as it supposes to be. I feel like people do stuff because they are told to do because they want to impress but not because they want to do so. Sometimes, it feels a bit fake. Not only me, I’ve talked to some people, and they have expressed similar concerns. However, this might be just some prejudices that I have against people in a school lead activity.
However then, I thought to myself, this is not about me, this is about the delegates who come to the conference. They want to get something out of it, they want to make connections, they are real people out there. So, for once, I shall not think about my own comfort, and just plan the conference. Once, I’ve accepted the fact, I think I start to see people from a better spotlight. Maybe, I was wrong, maybe it was me who’s not true to myself, maybe I was just not comfortable with a different group of people that I used to work with, maybe we all are in the same situation after all. I think my thoughts have evolved better for the group! 🙂
Then, back to my final group. I think we worked well together, we all each have an equal say in coming up with the conference. I can sense that everyone is comfortable enough in a group to comment on everyone else’s opinion nicely which is nice. Maybe, one more thing we need to work on is I think we are a bit behind schedule. I want us to finish the planning of the activities and prepare for every nook and cranny.
Overall, I am really, really excited to meet the delegates! I am ready to be inspired, I am ready to make connections!
This is my empathy map on how I think one of our potential delegates, “Grace” might be thinking or feeling in her head or heart right now in Myanmar to sign up for our IFP conference.
Enjoy the video! And have a nice day! 🙂
We had a joint Dover-East IFP session for TEDx with the theme of Peace by Piece. I have to say that it was a very beautiful and interesting experience. One of the speakers that I felt moved by the most is Joy. It’s the first time that I’ve heard that she used to be a refugee. I think it’s amazing and it kind of just trying to remind us again as to how you will never know what the person has been through just by the smile on her face. You might hate someone just by the fact of what you heard and saw, and that’s just so shallow of you. A girl you called a slut, she’s a virgin. A man you said he’s weak because he cries, her mother died. A student who slept in class and you called “lazy”, he got 9 siblings to take care of at night. Sometimes, what you see is just a small part of the truth, hence try to sit and talk to them first, about their lives, about who they are, getting to know them first, go deeper before forming a judgement IN your head. Because it can work the opposite, too, you never know that sometimes, the greatest sadness can also be found behind the greatest smile.
Another speaker that I really look forward to is Jean. The fact that I kind of know her personally, make things more interesting. And I really want to see how she’s going to make the connection between the cryptography to peace. And the fact that in the talk, she brings up the story of Alan Turing and the Enigma machine. Because it’s one of the saddest human real-life stories I’ve ever heard.
(Out of topic: I mean Alan Turing is a socially-awkward but a genius man. He spent years trying to break the Enigma machine and when he finally did it, he was told to keep everything a secret. One of the real-life heroes, Christopher has helped save millions of lives from the war. But during the life, while he lives, no one knew he’s the hero. No one knew he’s the one who has helped the country. All they ever did to Alan Turing, is treating him with awkwardness and disgust by the fact that he’s gay. The fact that he prefers to be with men is greater than the fact that he’s helped the nation. Which in the end, force him to commit suicide by biting to a cyanide poisoning apple. And only later on, then the fact that he’s the one to decode the unbreakable Enigma Machine surface in the society. And only after that, then the queen gives him a posthumous royal pardon for being convicted of having an affair with the same sex in 1952. What’s the use of that? The man lives his lives with the society frowning upon him. Humans… How do we know if there are in other cases like this that the government hasn’t let us know? And it’s just stupid that we lost one of the greatest minds in the world, the father of computer science, to the rights of one’s sexuality. )
Anyway, Jean reminds me that age doesn’t really matter. She’s really brave to go up there and talk about what’s she passionate about. And it just makes me reflect on myself whether I have been brave enough every day to just try and make changes in the smallest possible way in the world. I think most people have identified the difference they want to change, and we’ve discussed it every day. But sometimes I feel that it leads us to nowhere. People tend to complain a lot about things but do nothing about it. Jean makes me realise that “Don’t complain about things you’re not willing to change.”
During one of our mentor session, I and my partner, Sanah, went to a Grade 5 classroom and have a mini session introducing IFP with them. It was to bring in the idea of positive and negative peace, identifying the conflicts and different ways to solve the conflicts. First of all, I myself really did enjoy it. I like their enthusiasms, their willingness to participate in discussions and raise up their hands to voice in their opinions. It makes me feel that we actually have done a good job. So, this is not necessarily an informative and hopefully interesting session to them, but to us as well. Hence, it’s a 2-way beneficial session.
(Out of topic: No offence, but what I had in mind already for some times is that these small kids tend to be more passionate about different activities than teenagers. They are at the age to want and try new things. For example, if 2 same activities are done during lunchtime, I’ve observed that there will be more people during middle school lunchtime than the high school one. There might be several factors to this. I don’t know. I just want to put it out there.)
Anyway, I can see that they are very eager and they do know how to approach these conflicts. We are not there to tell them anything, they know how to approach it themselves. They also realize that in the real situation itself, it would be not as easy, but it’s worth to keep in mind. We are just there to remind them that they could this or that that they’ve discussed among themselves.
Talking about my skills in the session itself, I think my strength is that I can control the crowd really well. I spoke in a clear manner, sometimes crack a joke, but also serious when needed, I know my audience well, and how to make the most out of it. And one of my weakness in this session is that at one time when some group is speaking, the rest of the group in the far back corner might not really be listening. However, I can’t just cut in and move everyone to the front and make sure that they listen to each other because I also realize that we don’t have much time left. Hence, I just left it to go with the flow for the last 1 or 2 minutes. I think I should have calculated in my head, in the beginning, and bring everyone to discuss this together at the start.
This is me and my friends discussing on what activity or service that stands out the most for the past few seasons and reflect on how and why does this have an impact on us.
Thank you and have a nice day!
