UPSR SCIENCE: LIFE PROCESS (HUMAN) - Year 4
LIFE PROCESS THAT ANIMALS CARRY OUT
PROSES HIDUP YANG HAIWAN LAKUKAN
1. Animals carry out life processes that are similar to humans. / Haiwan melakukan proses hidup yang hampir sama dengan manusia iaitu:-
a) Excretion / berkumuh
b) defecates / bernyahtinja
c) breathing / bernafas
d) reproduction / membiak
EXCRETION & DEFECATION
BERKUMUH & BERNYAHTINJA
1. To get rid of waste product from their bodies. / Untuk menyingkirkan hasil buangan dari tubuh mereka.
2. The excretory organs of animals are:-
a) The lungs / peparu
b) The gills / insang
c) The kidneys / ginjal
2. Just like humans, animals need to excrete & defecate to stay healthy. / Seperti manusia, haiwan perlu brkumuh & bernyahtinja untuk kekal sihat.
EXAMPLES OF ANIMALS EXCRETE THROUGH THE LUNGS & KIDNEYS
CONTOH HAIWAN-HAIWAN YANG BERKUMUH MELALUI PEPARU & GINJAL
The cows / lembu
The cats / kucing
The monkeys / monyet
The whales / ikan paus
The dolphins / ikan lumba-lumba
EXAMPLES OF ANIMALS EXCRETE THROUGH THE GILLS
CONTOH HAIWAN-HAIWAN YANG BERKUMUH MELALUI INSANG
The tadpoles / berudu
The fish / ikan
EXAMPLES OF ANIMALS EXCRETE THROUGH THE SKIN
CONTOH HAIWAN-HAIWAN YANG BERKUMUH MELALUI KULIT
The earthworms / cacing
The butterflies / rama-rama
BREATHING
BERNAFAS
1. Different animals breathe through different breathing structures. / Haiwan mempunyai struktur pernafasan yang berbeza-beza.
EXAMPLES OF ANIMALS WITH THEIR BREATHING STRUCTURES
CONTOH HAIWAN-HAIWAN DENGAN STRUKTUR PERNAFASAN MEREKA
THE LUNGS / PEPARU
Breathing structure of a goat, a dolphin & a frog / struktur pernafasan bagi kambing, dolfin dan katak
The cows / lembu
The cats / kucing
The monkeys / monyet
The birds / burung
The crocodiles / buaya
The dolphins / dolfin
The frog / katak
The bat / kelawar
TRACHEAL STRUCTURES / STRUKTUR TRAKEA
The caterpillars / ulat beluncas
The butterflies / rama-rama
The grasshopper / belalang
MOIST SKIN / KULIT LEMBAB
THE GILLS / INSANG
Breathing structure of a fish / struktur pernafasan bagi ikan
REPRODUCTION
MEMBIAK
1. To maintain & increase their numbers. / Untuk mengekalkan & menambah bilangan spesiesnya.
2. Base on they way of reproduce, animals can be classified into TWO groups. / Berdasarkan cara pembiakan, haiwan boleh dikelaskan kepada DUA kumpulan iaitu:-
a) Reproduce by giving birth. / Melahirkan anak.
b) Reproduce by laying eggs. / Bertelur.
3. Mammals like cats, mice, cows, whales and monkeys reproduce by giving birth while reptiles, amphibians, fish, bird & insect are mostly reproduce by lying eggs. / Haiwan-haiwan mamalia seperti kucing, tikus, gajah, ikan paus dan monyet membiak dengan cara melahirkan anak sementara haiwan-haiwan reptilia, amfibian, ikan, burung dan serangga kebanyakkannya membiak dengan cara bertelur.
4. Animals such as cows, horses and elephant give birth to just one or two offspring at one time. / Haiwan-haiwan seperti lembu, kuda dan gajah hanya melahirkan satu atau dua ekor anak pada satu masa.
5. Animals such as cats, dogs and mice give birth to many offspring in one time. / Haiwan-haiwan seperti kucing, anjing dan tikus melahirkan anak yang banyak dalam satu masa.
An elephant giving birth to one offspring / Gajah melahirkan seekor anak.
A cat giving birth to many offspring / Kucing melahirkan banyak anak.
6. Some animals lay a few eggs and some lay many eggs. / sesetengah haiwan bertelur sedikit dan sesetengah bertelur banyak.
A chicken and a crocodile lay a few eggs / Ayam dan buaya bertelur sedikit
A turtle and a frog lay many eggs. / Penyu dan katak bertelur banyak.
LIFE CYCLES OF ANIMALS
KITARAN HIDUP HAIWAN
1. Some animals undergo changes as they grow. Sesetengah haiwan mengalami perubahan semasa proses tumbesaran.
2. They change in shape & size. / haiwan berubah bentuk dan saiz.
3. A complete process of change from birth to adult is known as a life cycle. / Proses lengkap perubahan haiwan dari lahir hingga dewasa disebut sebagai kitar hidup.
4. Different animals may have different life cycles. / Haiwan yang berlainan mempunyai kitar hidup yang berlainan.
5. The diagrams below show the life cycles of several animals. / Rajah di bawah menunjukkan kitar hidup beberapa jenis haiwan.
The life cycle of the butterfly
Kitar hidup rama-rama
The life cycle of the mosquito
Kitar hidup nyamuk
The life cycle of the grasshopper
Kitar hidup belalang
The life cycle of the frog
Kitar hidup katak
The life cycle of the chicken
Kitar hidup ayam
6. For young animals which look like the adult such as the chicken and the grasshopper are only slight. / Bagi anak-anak haiwan yang serupa dengan induknya, perubahan yang berlaku hanya sedikit.
7. For young animals which do not look like the adult such as butterfly, mosquito and frog, the changes are more complex. / Bagi anak-anak haiwan yang tidak serupa dengan induknya seperti rama-rama, nyamuk dan katak, perubahan yang berlaku adalah lebih komplex.
