Farm animals

Page 2: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

Cows, pigs, sheep and chickens are common farm animals.Farmers buy and sell them, or keep them to produce foodand other products.

Page 3: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

Sheep live in fields. They are herbivores. They eat grass, hay and grain.

cows live in fields and in sheds. They are herbivores. They eat grass and cow feed.

Page 4: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

Pigs live in pens. They are omnivores. Farmers give pigs grain and specially prepared pig feed.

Chickens live outside and stay in copos at night. They eat grain and corn, but also worms and insects.

Page 5: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

COWS are mammals and produce milk for their newborn babies.

A baby cow is called a calf.

Cows usually give birth to one calf at a time, but they can have twins or more.

Page 6: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

sheep are mammals. A baby sheep is called a lamb.

Lambs drink their mother’s milk when they are born.

Sheep can give birth up to three lambs at a time. Lambs are usually born in spring

Page 7: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

pigs are mammals and produce milk for their newborn babies.

A piglet is a baby pig.

Pigs can have up to 12 piglets at a time! A group of piglets is called a litter

Page 8: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

chickens are birds and their babies develope inside eggs.

A baby chicken is caled a chick.

Chickens can incubate up to 12 chicks at a time, and lay more tan 300 eggs a year.

There are al sort of mammals on the planet. Dogs, dolphins and bats are mammals, but they look very different. Mammals can be very big like whales or elephants, or very small like mice. All mammals are vertebrates

Most mammals have fur or hair. Fur and hair keep the animals warm.

Most mammals have four legs and move on land, but some mammals have flippers to move in water. There is a mammal that has wings.

There are al sort of mammals on the planet. Dogs, dolphins and bats are mammals, but they look very different. Mammals can be very big like whales or elephants, or very small like mice. All mammals are vertebrates

All mammals are viviparous, except for monotremes, which are oviparous.

mammals

Mammals can be carnivores, herbivores or omnivores. They have different types of teeth depending on the food they eat

Baby mammals drink their mother’s milk until they can find their own food

All mammals breathe with their lungs

Page 11: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

Equidnas are monotremes. Monotremes are oviparous mammals. Equidnas live in parts of Australia and New Guinea

Elephants are are the largest land mammals. They are hervibores

Giraffes are the tallest land mammals. Their necks are long so they can eat leaves from tall tres.

Page 12: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

Bats are the only mammals that can fly. Most bats are nocturnal. This means they are only active at night.

Dolphins use flippers to move in water. They breathe through a hole at the top of their head. They are carnivores.

birds are vertebrates. There are thousands of types of birds. Birds come in all shapes and sizes.

Birds are oviparous. They incubate their eggs. This means they sit on the eggs to keep them warm while the baby grows inside

Birds can be carnivores, hervibores or omnivores

Adult birds find food for their babies until they can find their own food

birds are vertebrates. There are thousands of types of birds. Birds come in all shapes and sizes.

Birds have feathers and wings, but not all birds can fly! Some can swim or run. Birds use their feathers for flying, keeping warm and attracting other birds. All feathers are waterproof

Birds have beaks. Birds of prey have hooked beaks for tearing meat. Birds that eat nuts and seeds have short beaks. Birds that catch fish have long, sharped, beaks and birds that eat nectar from flowers have long, thin beaks.

Page 17: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

Penguins are aquatic birds. They mostly eat fish and other small sea animals. They can’t fly, but they are very good swimmers

Eagles are carnivores. They are very good hunters and eat fish and other animals. Bald eagles make the largest nest in the world.

Sparrows have short beaks because they eat seeds

Page 18: UNIT 4. NATURAL SCIENCE: MAMMALS AND BIRDS

Ostriches are the largest bird in the world. Although they can’t fly, they can run faster than any human.

Pelicans have large beaks which they use to catch lots of fish at once.

Hummingbirds are one of the smallest birds. They have long, thing beaks which they use to drink nectar from flowers.
