The Third Day Of The NSS Taster Program ( By Elizabeth Chan)

Today is the third day we have the NSS Taster program. We had the VA, English, Chemistry and Geography.

In the Chemistry lesson, we has known that the things that we will learn in form 4 and what we need to have if we really want to study chemistry for our elective subject. We also do some of the experiments that form 4 will do. The first experiment is to prepare the raw materials of chlorine bleach. In this experiment, we are going to electrolyse concentrated sodium chloride solution, and to test the properties of the products. The second experiment is to study the bleaching action of household bleach. In the both of the experiments, we had known that many things that we didn’t learn in our lesson. For example: we had known that household bleach is alkaline. Also, household bleach should not mix with the other chemical solutions. This is because toxic chlorine gas will be given off if we mix chlorine bleach with acidic chemical.

In the Geography lesson, the teacher told us the structure of NSS Geography. Also, we had many activities during the lesson such as we need to put the names of the places of Hong Kong on the right place of the map.

For me, I will choose chemistry for my elective subject. I think this is very interesting and I think this will not make me boring. There are many experiments we need to do. Although some of them is quite dangerous, I still hoping to do the experiments. I knew that almost everyone in our class wanted to choose chemistry for their elective subject, and because of this, I need to be more hard working.
