Maths: Algebra

WOW. I love Maths.



I learn theres a different types of algebra which includes factorisation, Expansion, Cross factorising and many more.



Here is an example of basic expansion:

*(a+b)(a+b) =a square + ab +b square

*Note that I can`t use square on computer that why I type it as square.



Example of Factorisation:

a square + a + b square + b

= a(a + 1)+ b(b+1)



Hope It`s alright of what I type.

Science: Sexual Education

Talking about sex. At first it sounds awful as this is not the topic in mind but since its for studies then it alright cause nowdays teens does not really know the consiquences of sex.

Before I start about it I know two types of sex which is:

1)Asexual-- Is only for unicellular cell like yeast and bateria since it only a single cell organism.


2)Sexual-- Is sex that requires the male sex cell (sperm) and female sex cell (ova/egg) to form new life.

Premarital sex is when a sex was unplanned normally before the couple married.

Here are some example of birth control(contreception):

1)Rhythm method:


- sex after menstruation but before ovulation.

- Use of condoms for men.

- Use of spermicides,the pill, cap/diaphram



*Note: IUD(Intra-Uterine Device) is not a form of birth controll as is does not prevent pregnancy but is does not allow the embryo to implant the wall of uterus.



2)Pemenent method:

- Vasectomy-- for men which is cut and tied at the sperm ducts.


-Lagitation--for women which is cut and tied at the fallopian tube.



Sex Desease:

1) Gonorrhoea-- Cause blindness to new born baby etc.Cured only by anti-biotics at early stage.



2) Syphilis-- Cause sores to mouth and reproductive area and blind,deaf or even death to new born baby etc. Cured using anti-biotics like gonorrhea at early stage.



3) AIDS(normally from a desease which is HIV)-- Cause fatigue, severe diahorrhea, sweat at night and loss of weight etc. There is no cure for AIDS.



This is cause due to:

- Sharing of drugs or needles.

- Sex with an infected partner.

- Infected women to baby through breastfeeding.

Pastoral Care Reflection

3 thing I have learnt

1. I learn how to communicate with others without talking instead to use body gesture to communicate with each other.
2. I learn the responsibility is important without it everything will be in up-side down.
3. I learnt how animals could reassemble us.

2 things I could apply.

1. I could apply the first one which is to use body gesture to communicate and this help to reduce the noise pollution.
2. I could apply the second one which is about the important of responsibility and this is useful in future.

1 thing I want to know about my friend is what most of them like to do mostly if there is nothing bothering him/her.

Re: Science Practical

Q:What have I learnt in the practical session?

A:I learnt that safety always comes first in practical and always use safety goggle when doing heating to prevent anything from entering to our eyes. I also learnt how to observe things in the practical that is required to do.

Q:What difficulties I faced while doing the experiment?


A: Well...Only the heating part as fire was my fear in practical since from the case I accidentally almost get my hand burn and also I had once accidentally touched a hot test-tube that had just been remove from heating(because I was too excited untill I forgotten about the heat.) but luckily it does not injured my fingers. It was almost unlucky to me in practical.

Q:What do I want to learn more about this chapter?

A: I want to learn is can all compound really be separated or change into another substance by just using heat or does it still need electricity for some of the substance.

Review Chapter 2.1

Q:What have I learn in Chapter 2.1?

A: I had learn new things and also recap about ALGEBRA that had been thought before. It was very interesting although a bit confusing.

Q:What are the difficulties I face?

A: The difficulties I face was to understand some of the thing like when cross multiplying and some of the algebra question does make me confusing.

Q:What you want to learn more about chapter 2.1?


A: I want to learn more about the cross multiple of which sign shall I need to change and some of the strategies of understand it more easily.

Maths Project

I manage to do my project with my teammates as they had help me and i really appreciate their help. Although the project was difficult, I tried my best to do it. I am really felt like i`m the one who is the blame cause normally I don`t make better friend like others did. I felt lucky that at least this year was a better year then last year.
