2 June Monday (Pre Camp)

Fastest Ball Challenge:
  1. What sounds interesting about this project?
    This project sounds interesting to me as instead of being a school assignment and a task, it is known as a challenge. This makes me want to participate in the project and be able to win the challenge. The project is also about making a ball go really fast which also interest me as it causes me to think how can it go fast and what are the factors.
     
  2. What do I think I can learn from this project?
    I think I am going to learn about the different factors of making something move faster and the theory or physics behind this
     
  3. Any immediate questions regarding this project?
    NIL
Extraction of Caffeine from Beverages:
  1. What sounds interesting about this project?
    Extracting Caffeine from Beverages sounds like we are going to do some hands on activities and do some experiments. I like hands on activities as I get to remember the things that I had learnt easier and I get to have much more fun then listening to lectures.
     
  2. What do I think I can learn from this project?
    I think I would be able to learn much more about caffeine and also different ways to extract it from beverages that we drink.
     
  3. Any immediate questions regarding this project?
    How much caffeine is actually too much for us humans?
3 June Tuesday (First Day)
  1. What did I do today?
    Today my group did the Fastest Ball Challenge First. We had to roll a metal ball down and ramp and we were given Photogate sensors to time how fast the ball could travel. We had to do trial and error to change the set up and make the ball move faster. Our group changed the angle of inclination of the ramp and one by one took the timings adding or subtracting the angle to finally get our desired angle. We had a lot of difficulties as we did the adjusting as we were not measure the angle properly causing us to restart our investigation at some point. Eventually we had two angles and had to chose one of them. Then Dr Ho, our mentor, had a short lesson with us on the physics to answer we get and taught us the formula to it. After this challenge we checked out the 3D Printer at NTU and saw how it actually prints things such as ear rings and chains. We had to use some little solid tokens of different shapes made by the 3D printer to do the next challenge which was the fastest dive challenge. We had to put the token into two different groups the light and the heavy one and also chose the fastest out of the two groups that would dive to the bottom of a cylinder of detergent. For the second challenge our group was the last as we thought we had to use the slowest to win the challenge and everyone had to wait for the token to drop to the bottom. We had a lot of fun while waiting and laughing about how slow it was. We ended the fastest ball challenge with this and went on to do the next project. For this project we had to make 8 teabags by ourself scooping the tea leaves into each teabags and measuring them with the weighing machine. After making the teabags we are done for the day and headed back to school. 
     
  2. What did I learn today?
    I learnt about the concepts of conservation of energy, kinetic and potential energy that would effect the speed of a rolling object. I also learnt the about the formula to get the angle of inclination of the ramp and also how the surface area of the object also affects the movement of the object.
     
  3. How do I feel about today's activities?
    I feel that today lesson was very fulfilling and very engaging. I would like to thank our mentor, Dr Ho for being so patient with us and making the day so productive and interesting. I learnt a lot in this project and had as much fun too. I also feel that now I know much more about how physics is applied in the real world and how physics has made our lives easier.
4 June Wednesday (Second Day)
  1. What did I do today?
    Today we used the 8 teabags we made and also another 8 Lipton teabags and start on the extraction of caffeine from them our group was divided into 2 and 2 of us did on the handmade teabags while the other 2 did on the Lipton ones. I did the handmade ones and we had to start on the extraction. We did the Büchner Filtration, the Solvent Extraction and lastly we used a Rotary Evaporator for the distillation. Eventually we got the final product which was the solid caffeine. After this we had presentations by the Dr Ho and the project advisors on the two different projects before we were given time to do our presentations.
      
  2. What did I learn today?
    Today I learnt how to use the Rotary Evaporator and learnt how to do a Büchner Filtration. Basically I learnt different ways of extraction that I have never done before. I also learnt much more about caffeine, its positive and negative effect to humans.
     
  3. How do I feel about today's activities?
    I feel that I have learnt much more from today's activities and I am able to use this knowledge in future. I really want to the the project advisors for helping us out with this complicated experiment and simplifying them for us. I really appreciate it that they not only helped us out in the experiment but also put in the effort to explain the use of each step for us to understand the process too. These knowledge and steps I learnt are used in daily lives and I glad to be able to use them for future purposes. It was fun to be able to try out new things and challenge ourselves in this new experiments
      
  4. What new questions do I have regarding the discipline?
    NIL
5 June Thursday (Third Day)
  1. Plenary Sessions
    I learnt how did the 3D Printer came about
    I learnt about what the 3D Printer can make now
    I leant about what 3D Printer is going to be used for in future and developing research on it.
      
  2. How do I feel about the SST-NTU Flagship programme?
    The programmes allowed me learn new things in a different and more interesting way. It also helped me learn more about science and its real applications that I have never known before. The presentations by other projects also allowed me to learn knowledge outside my project. Overall it was engaging, applicable and knowledgable.
