Reflections Day 1

Project 3A~

This project aka Project 3A sounds interesting as we would be doing The Fastest Ball Challenge and it seems interesting as there are different variables that we can change to make the ball travel the fastest. 

Through the first project I think I can learn the concepts of conservation of energy, kinetic and potential energy. They will also learn how to use photogate sensor for data acquisition. 

I hope to know the ways to enable the ball to move the fastest.

Project 3B~
The second part of the project is the Extraction of Caffeine from Beverages which is on Chemistry and it seems interesting we get to learn the various ways to extract caffeine from various beverages. 

Through this second project, I think that I will be able to learn about caffeine which is a type of alkaloids.

I would like to know how to extract caffeine from various beverages and if there are different methods to it. 

Plenary Sessions

Plenary Session 1...
People do mapping and collect layers of sand to determine the age of the tsunami and determine whether they are from tsunami. With the sand collected, they use a method called radio carbon dating, allowing them to find out the size of the tsunami. Also, as time passes, islands will sink. When an earthquake takes place, it causes the island to suddenly rise and thus causing a tsunami to take place. This is 
not the only way that people can tell the frequency of the tsunami as well as the strength of the tsunami. They are able to tell by researching based on the corals that they collected. 

Plenary Session 2...
Animation is drawing and capturing frames and putting them into sequence and when it is looked through at a fast pace, becoming an animation clip to tell a story. 2D Animations are more costly than 3D Animations however 2D Animations are still in high demand. This is because, 2D animations are laborious and requires a lot of time to be produced, thus increasing the cost of creating just one film. Traditional 2D animations made use of what is known as cells to create the scenes. They also coloured the drawing after the various scenes have been drawn. Thus, this requires a lot of professionalism in drawing and also in adding in colours. Despite all these differences, sometimes 2D animations can be coloured in a way to make it seem as though they are 3D.

Plenary Session 3...
Nanotechnology begun since 1959. Nanotechnology mimics nature to create appliances such as sunblock and skin cream. Nanotechnology is able to let one manipulate the atoms which are very small in size. There was once when Richard P. Feynman set a challenge of making his 1959 speech shrink 25,000 times. This was made possible and the technology now has enabled even NTU to be able to print words onto something as thin as a strand of hair. The other challenge Feynman set was so create a motor as small as a pinhead. This was also created in around a month's time. However since the motor was so small, there was a high amount of heat but where could it be transfered to in such a small object? Thus in 10 seconds when the creator of the motor was taking a picture, it had melted through the table.
