Term 3 test reflections

Well even though I have committed some mistakes I should never have committed if only i had revised harder but still overall, I am quite pleased as I managed to obtain an A2 in the test even though it was considerably harder than the previous test seeing that so many of my classmates had gotten Cs. But still I am very sure I would have scored higher if only I had payed much more attention to word equations and memorising what is the word equation for some compounds and elements. Another thing I should take note is not to rely too much on the powerpoints and take notes on what Mrs. Chu has said as can be seen when I got the question on the first page of Section B. It went like "A mixture with two elements" and they expect us to pick one material from the box. I got the question wrong which resulted in me getting the sub -questions wrong and in the end I had been deducted a total of 4 marks which is the A1. This is because I had assumed bronze to be a compund and seawater to consist of 2 elements only, both of which Mrs. Chu had said in class but was not in the powerpoint. Yup, that's about it, sure hope I can improve by 1 grade again and redeem my glory in term 1.

How will I improve next term.

Well actually I have already done so by checking what are the topics to be tested next term and will be making use of the June Holidays to revise for these topics using my textbooks and the World Wide Web. Not only have I taken the measures mentioned to increase my grades by at least 1 but have also taken to task to print out all powerpoint slides that are related to the tested topic. This is because I have realized that most of the information for the test are given in the powerpoints and it also serves as a complementary revision resource. Hope I will get at least an A2 or A1 in term 3!

Term 2 test reflection

From this test's result I am starting to get a sensing of how much harder I have to work and revise should I want to attain an A1 again as i have only gotten a B3 this time round. I felt I could do a lot better if I had familiarised myself with the elements, compounds and mixtures segment as I had not bothered memorising and understanding all the elements, compoundas and their functions. Although I think I had understood the topic generally as I was able to get all the MCQ questions right. But once again because of my failure to memorise all the compounds symbols I did pretty badlt in the word equations component of the test which attributed to my B3. Although I think I have understood how word equations work from the fact that I had gotten the bonus question right which was a question on word equations. I just hope I will improve by a grade in term 3.;)

Interesting facts on term 1 topic.

Here are some interesting facts about the topics so far:

1. Did you know that before the scientific method was made, scientists back then used their imagination to explain the universe. PRoblem is evryone accepted their ideas and Galileo Galilei was executed for going against these ideas.

2.Did you know it was Aristotle who first gave the idea of making observations before concluding that one's theory is true which is the gist of the scientific method, but never walked his talk.

3.Did you know that the scientific method was never invented by one person but was slowly established over the years, still the person that did the most contribution was Roger Bacon who introduced the idea of inductive reasoning.


4.Did you know that before modern apparatus were invented, ancient lab apparatuses were made out of bones and clay.

5.Did you know that most modern apparatus's structure were derived from ancient lab apparatus.

6.Did you know that the genius physicist, Albert Einstein, rarely made use of a lab to conduct experiments, he carried out mind experiments as most of his experiments required machines that haven't even been invented!

What I wish to learn and how I want to improve in term 2.

In term 2 I like to learn more about chemistry and biology as i wish to become a doctor in the future. I am especially interested in chemistry as it is very interesting to observe the different interactions between chemicals, I also wish to learn more about compounds, elements and mixtures. Also in term 2 I will pay more attention during class and try to catch up on my notes everyday. Basically I hope to do a lot better in term 2 and at least try to be the top 4 in class.

Things I have learnt in Term 1 and reflections on lessons.

In term 1 I have learnt how to treat learning science with an open attitude, use the scientific method to solve scientific problems, make use of science laboratories to conduct science experiments and many more. The lessons were most effective in allowing me to foster a positive attitude towards science which is the main objective for term 1, so in all there were absolutely no problems with the lessons. In fact the practical lessons done in school were much more exciting then the practicals lessons done in primary school because back then we were only experimenting on things such as the effects of carbon dioxide on lime water and most of the "cooler" experiments are done by the teacher. Whereas in secondary school, it is pure independent which is what helped me build up a strong liking for science as I realised it is much more than theory but also about experiencing. Still I hope that you would organise a monthly field trip for the class, I know it is asking a lot but if you were to allow only the top 4 boys of each class to attend a field trip, the rest would not get a chance to experience other aspects of science. I understand that these boys would have done exceptionally well to be able to attend the fielsd trip but i hope you would try to organise some field trips for the rest of the class too.

Reflection on Term 1 test

Well on the whole I felt I did not bad as I have gotten an A1, although some mistakes I made should have never been committed if I had revised much more thouroughly while some mistakes are just due to my carelessness. For example in question 4 in section B the question clearly states that bases react with acids to give salt and water only, but I was daft enough to put classify calcium carbonate in bases even though it reacts to give salt, water and carbon dioxide. If I had been more careful and revised more thouroughly I might have not committed mistakes I otherwise would not have commited and might have earned myself the trip to the Metrology station.
