Lesson 1: We learnt about the lab rules.


From this activity, i have learnt about the rights and wrongs in the lab.

Lesson 2: We heated an ice-cream stick and learnt about the types of flames as well as the parts of a bunsen burner.



From this lesson i learnt that luminous flames are less hot than non-luminous flames and that luminous flames produce a lot of soot and is unstable while non-luminous flames do not produce a lot of soot and are stable.

Lesson 3: We mixed chemicals together and watched the chemical reactions



Lesson 4: We observed water boil to a temperature of 100 degrees Celsius.

Lesson 5:We observed the number of swings by the pendulum bob when at different heights.



I learnt that we have to record the time taken for the bob to make 20 oscillations to ensure a fair test.

Lesson 6: We learnt how to use the vernier caliper and the micro meter screw gauge.







We learnt about distillation today, this is just simple distillation and distillation is one of the many methods use to separate physical solutions and suspensions.

This was when we were burning magnesium! its so bright!!!!!!

This is the Benedict solution being boiled. Its show us if it contains glucose!

This was one of our last experiments, chlorophyll separation

Reflections on termly personal performance and growth development in Science:

a) My target for all my science tests are A1. My reasons for setting my targets so high  are because i feel that science is one of my strongest subjects and i need to use this to pull up my MSG as my languages are weak. I plan to improve by buying assessment books to practice on. For my class tests, i was very careless and thus i made many careless mistakes.
b) Actually, i understood perfectly what my teacher said in class so far. But if there there were any parts which i did not understand, i would either search the internet or ask my tuition teacher for clarification.

 Issues in teaching and Learning Science

Problems that you faced in the learning of Science and how you overcome these problems?

When i first entered Hwa Chong, i found out that my science was only average, i big difference then when i was in primary school. I found out that my weakness was that i was unable to comprehend what we were studying during term 1 due to the fact that i didnt care. Thus my test marks only gave me a B3.

In Term 2, i became addicted to s computer game, thus i hardly focused in my work. Also, i had a big problem with remembering how to convert cm to cm2 or cm3......  This was mt greatest downfall because it was the highest weightage in the test. 

In term 3 i decided to improve my MSG because i was doing badly in my subjects. I went for extra tuition to catch up with the syllabus and finally got an A1 with a score of 39/45, 4th in class!!!!!! From this i have learnt a valuable life lesson being, hard work always pays off. All those sleepless nights and sweat finally gave me the result i hoped for.

Hi everybody! my name is Gan Wei Lun from Hwa Chong Institution. I am fun loving, happy, sporty, honest and opinionated. My hobbies include reading, watching movies and engaging in outdoor sports. However, my favourite hobby is playing tennis. Although tennis is my hobby, I also play it competitively and I'm currently seeded 8th in Singapore for doubles. I am in the school's tennis team and I hope to bring glory to my school in the upcoming inter-school competition which will be held in March. Tennis has taught me many things, such as sportsmanship, perseverance, determination, teamwork and to strive for excellence in whatever I do.

I'm an optimistic person who is positive about every aspect of life. There are many things I like to do, see, and to experience. I love to read, especially on Greek mythology.

I have two siblings and they are both in Nanyang Primary School. My brother is in P6 this year while my sister is in P4. My brother will be taking the PSLE this year and I am hoping that he can join me in Hwa Chong next year!!
