The first plenary session was on the topic Water - Clean and Dirty. I learnt that dirty water has many negative effects on people, and is a very real problem for many people in many other countries. I feel that since we are fortunate to be born in Singapore and have access to clean water we should help others to be healthy too.
The second plenary session was on the Revolution of Microelectronics Technology. I was not really interested in the talk but I still remember the 9 'O's and the B.R.A.I.N.W.A.V.E.
The third plenary session was about Biomedical Engineering & Technology. I learnt that Nano Technology is useful and also it makes things smaller in the same volume and gains more energy.
The fourth plenary session was on IT for Animation and I learnt more about stop motion, 2D animation and 3D animation.
The fifth plenary session was on Disappearing glaciers, rising sea levels, and why gravity is even more important than we think. I learnt about how the gravitational pull of the glaciers affects the sea levels when it melts.
I found the plenary session on Water - Clean and Dirty most interesting. This is because I find it easy to understand and there is something for me to do to help.
