Shape and Space -Mathematics

Let's hear the shapes song before we learn more! Make sure you hear it until the end because I love the ending!

Two-dimensional shapes (2D Shapes):

Three-dimensional shapes (3D Shapes):

Sometimes, there are questions that involve us to name the
names of 3-D Shapes. I would advise you to remember the

Perimeter

How to calculate the perimeter of a shape. Example:

Perimeter Rectangle= (5cm+5cm+12cm+12cm) Two lines have same length

                              = (10cm+24cm) ----> 34cm

Perimeter Square= (5cm+5cm+5cm+5cm) All of the sides are of the same length

                         = 20cm

Perimeter Triangle = (5cm+7cm+6cm) According to the type of triangle

                             = (12cm+6cm) ---> 18 cm

Area

Area of a square: length x breadth (a x a)

Area of rectangle:length x breadth (a x b)

Area of a triangle: length x breadth, then divide by 2

Volume

Volume Square: length x breadth x height (a x a x a)

Volume rectangle: length x breadth x height (a x b x c)

Interesting facts!

I have been reading some very interesting books that contain fascinating facts. I felt that it would be great to share it with all of my delightful readers..

• Spider silk, by weight, is stronger than steel!
• Tigers have striped skin, not just striped fur.
• A crocodile cannot stick its tongue out. (I guess ice-creams are not ideal for crocodiles!)
• A polar bear's fur is not white, but translucent
• Honeybees kill more people than venomous snakes do. (The cute honeybees kill us people more than snakes! Frightening!)
• Jupiter is bigger than all the other planets in our system combined. (Wow, that's big!)
• Donald Duck (From Mickey Mouse) comics were once banned in Finland because Donald does not wear pants. (Ha, ha, ha! My stomach aches from non-stop laughing!)
• Karate originated in India, but was developed further in China.
• Sound travels through water three times faster than through air. 

Some thing funny that has to do with the last fact:

Person: Look! There's a chicken crossing the road! There's a truck coming! What's he trying to do? Get to the other side?

Chicken: Yeah, yeah! I've heard that 'Why did the chicken cross the road?' jokes, THANK YOU VERY MUCH!

(This situation shows why 90% of extinct species are birds!)

Investigating Living Things -Animals

Living things interact with one another in the environment. An animal interacts with plants and other animals.
Two common forms of interaction among animals:

• Competition
• Cooperation among animals

There are animals which live alone or live in groups. The animals that live alone are also known as 'Solitary animals'. 

There are reasons why animals live in groups or solitary. 

-Why animals live alone:

• To avoid competition for food, space and more things.
• -To move around quietly without attracting any attention. With no noise which attracts their prey, their prey would not notice its enemie.

-Why animals live in groups:

• To have cooperation with each other for protection.
• For protection. 
• For food. They can work together to look for food.

My pages

Just in case all of you readers do not notice, I will tell you it. Some people don't really notice the tabs which are situated under the blog title. At the moment, there are three tabs:- Home, English and Bahasa Melayu. Please feel free to look at the English and Bahasa Melayu pages.

Microorganisms related to food

Microorganisms related to food:

Bacteria in Yogurt

Yogurt is made by boiling milk and adding special bacteria on it. Then, it is kept warm for several hours. The reason why it is kept warm for several hours is so that the bacteria multiplies and turns the sugar in the milk into acid. The acid makes the milk go thick and also stops the breeding of bacteria. Interesting, right? I had just know this and was very fascinated with this yogurt-making process so I wanted to tell all of you, my readers, about it. Did you know? The bacteria in the yogurt is good for our digestive system!

Yeast in Bread

A microorganism that is already well-known as is used in many bakeries called 'yeast' is added to the dough to help the bread rise. The yeast turns the sugar in the dough into carbon-dioxide. As the dough is heated, the bubbles carbon-dioxide get bigger and then the bread rises. I know that yeast helps to make the dough rise before, but I have never known why and how it rises! Very interesting!

Uncooked food

Uncooked food (especially meat) sometimes contain bacteria that is called, 'Salmonella'. Salmonella is not good for us, but usually, this bacteria will be killed after being cooked. If you eat food that has not cooked properly, the 'Salmonella' may survive and cause your gut to multiply and make you very ill if you eat it. Better be careful! Always take care of your health so that you can keep on reading my posts on this blog. :)

1. Machines are tools that help us do work faster and easier. For example:

a)  help us carry heavy things
b)  wash our clothes
c)  travel faster from one place to another

With these machines in our life, our time and energy is saved. We use many machines in our daily life. Examples:
