Technology Around Us

Technology is important in everyday life. Imagine life without technology.
Look at some examples of technology shown in the video clip.

Human are able to overcome their limitations. Devices are used to overcome the limitations and problems faced by humans.
  Examples :  Unable to see the fine details of an object.
                   - telescope,microscope, magnifying glass, 

                   Unable to speak loud enough to someone to hear
                    - megaphone, microphone, telephone
                   Unable to walk long distances.
                    - aeroplane, train, car, bus, taxi

Technology in Communication

  Telegraph and devices such as the telephone allow humans to
     communicate with each other in far away places.
  Today, these devices are known as telecommunication technology.
     Examples : computer, satellite, teleconferencing, handphone,
                     fax machine 

Technology In Transportation

    Besides land transport, humans also develope better and faster  
        water and air transport. These devices shorten the 
        travelling time.

Technology In Construction
   A long time ago, humans lived in caves and built houses from
       clay and parts of plants. However, these shelters were not
       safe. They were nit strong and were easily destroyed.
  Today, most houses are built using bricks, concrete,
       and steel. These materials are stronger.
  Humans are now able to build bigger and taller buildings.
       examples : terrace houses, bungalow, apartments,

Technology is invented to solve problems in our daily life.
Technology can benefit mankind if used wisely.

Unit 2 Manusia Bernafas/ Humans Breathe ( Update blog )

Humans Breathe/ Manusia bernafas
( Dalam unit 2, Murid Tahun 4 akan belajar mengenai cara/ proses pernafasan manusia)

In unit 1, we learnt that humans need air to breathe.  In unit 2, We learn about humans breathe.When we breathe, we inhale ( take in ) and exhale ( let out ) air. How can we tell ? Our chest moves up and down. The number of chest movement is the rate of  breathing.      
As we inhale, the chest rises outwards and upwards causing the chest to expand. The air is taken in through the nose, down the windpipe into the lungs. this air contains more oxygen.
As we exhale, the chest moves in causing the chest to contract. The air inside the lungs then flows out from the lung to the windpipe and then out through the nose.

Proses pernafasan manusia adalah seperti berikut:

Hidung - saluran udara - peparu

Benda Hidup

 Keperluan asas haiwan ialah : udara, air, makanan dan tempat perlindungan.

Owls are a group of birds that belong to the order Strigiformes, constituting 200 extant bird of prey species. Most are solitary and nocturnal, with some exceptions (e.g. the Northern Hawk Owl). Owls hunt mostly small mammalsinsects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except Antarctica, most ofGreenland and some remote islands. Though owls are typically solitary, the literary collective nounfor a group of owls is a parliament. Living owls are divided into two families: the typical owls, Strigidae; and the barn-owls, Tytonidae.
