                                                 Term 2-Secondary 1 

     Time flies! Now Term 2 has come to a closing. Overall, it was alright, with my science common test achieving an A1. I can do better actually, I feel. keep improving, that's it.
     To start off, I'm going to talk about some problems I faced this term. For one, we just started on the topic of elements a while ago. Needless to say, the problem of memorising the periodic table came out. Even though it may not be tested in exams, the knowledge of the periodic table will come back and bite you in other nicely phrased questions, just like one I encountered in the common test asking for the symbol for Nitrogen, it indirectly points us back to the periodic table! So, I set to work. I would start by going through the first five elements, followed by increasing it to 10 and so on. In the end, it turns out that memorising that large chunk isn't that hard anymore.
     Next is a mini- mistake of getting solvent and solute mixed up. (Solvent is the one dissolving solute) To overcome this problem, I relate 'solvent' to 'movement', which allows me to remember that solvent is the active one while solute is the passive one. It's quite a useful method actually, which can be used in other aspects of remembering.
     Now to the scientific concepts I learnt. This term has been a fun-filled term, with new and captivating topics like 5 states of matter, solubility, Filtration methods and many others. These concepts are very much relevant to our world now. Take for example 5 states of matter. Look around you. Everything around you must be made up of any 1 state. Doesn't this topic open you up to start admiring the world around you? As for solubility, without it, we wouldn't have soothing drinks like Milo or even any soft drink you can think off! Last is filtration methods. Think about it. Without filters, we won't have reverse-osmosis(I did a write up on this found here), or in other words no drinkable water and wouldn't be able to separate mixtures like salt and water, which means no salt, leading to many inconveniences in our lives right?
     To end this off, I would like to talk about some things I have learnt out of my textbook. For one, I did manage to learn a bit about enzymes and how they work through my termly sabbatical, Science Eureka. I also gained some exposure to how Singapore's water filtration system works through these blogging. Last but not least is knowing a bit more about asthma, which kills two birds with one stone by 1) keeping up with current affairs and 2)learning more about the chemistry of how one symptom leads to another.
