What i have learnt this term

Something interesting i learnt from Mr lyndon lim, is that not all parts of the school has equal stability. He said that the toilet has the least stability and if too many girls are in one cubicle, for all we know the floor might crack and just fall causing serious damage. During lessons, we have watched many airplane videos and i have gained much knowledge from them. Some of them teached me about how the planes work. One example is that there are small turbines that generate electricity when the plane has run out of fuel. Another example is how the fuel engines work- X-feed and so on. In all, iwould like to continue in ESP and learn more interesting stuff/ facts.
