Essential Learnings by end of year 5: Science:
Life and living
Living things have features that determine their interactions with the
environment.
• Living things can be grouped according to their observable characteristics e.g.
insects have six legs; marsupials have pouches; fish have gills and fins.
Outcome:


Identify similarities and differences between animals.
Group animals and explain criteria eg number of legs, wings/no wings on
which the groups are based
Lesson Content:
Introduction: What ways can we classify different sorts of animals?
Explain that today we are looking at ways to classify animals
Activity: Classifications are used to group different things. There can be many ways
to classify. Each table group has an envelope of animals and a piece of A3 paper.
They need to come up with as many different ways of classifying the animals as
possible, for example: Number of legs, if they have wings, where they live, colour,
how they move, animals that swim, vertebrates, invertebrates, mammals…..
What categories could we use to classify animals?

Animals are divided into two main groups. Animals that
have a backbone are called vertebrates. Animals that
don't have a backbone are called invertebrates.

Vertebrates and invertebrates are divided into smaller
groups. Vertebrates, for example, are divided into
mammals, birds, amphibians, fish and reptiles.
ANIMAL GROUPS
AMPHIBIANS

Frogs, toads, newts and salamanders are amphibians.
Amphibians are cold-blooded.
Amphibians spend part of their lives under water and
part of their lives on land.
They lay jelly-covered eggs in the water.
Amphibians breathe with gills or lungs or through their skin.
Baby amphibians live in water and breathe with gills.
An amphibian's skin is moist. (They do NOT have scales.)
Amphibians are vertebrates -- they have backbones.
Most amphibians live in or near water or in damp places.
BIRDS
Next to mammals, birds are the most useful to man. There are thousands
of different kinds of birds. They vary in size from the tiny hummingbird
to the large ostrich.



A bird is an animal with feathers.
Birds have two legs and two wings.
Birds have a beak or a bill.
They lay eggs. The young hatch from the eggs.
They are warm-blooded.
Birds breathe faster than mammals and their bodies are warmer. Only
mammals and birds are warm-blooded.
ANIMAL GROUPS - FISH





Fish are cold blooded.
Fish lay eggs.
Most fish are covered with scales.
They have fins not legs.
Fish live in water and breathe through gills.
HOW A FISH BREATHES
The fish takes water into its mouth. The water goes back through the
gills. Then the gill cover at the side of the fish's head opens and the
water runs out. This intake of water gives the fish oxygen.
If a fish is out of water for a while, it will die because the gills will not
work unless the fish is in the water.
note:
Not all animals that live in water are fish.
Whales, dolphins and seals are mammals.
The sea turtle and other reptiles live in water.
Many amphibians live in water.
INSECTS
<>
Some insects that we know are crickets, ants, wasps, bees, grasshoppers,
beetles, moths, dragonflies, butterflies and flies.
WHAT ARE INSECTS ?

Insects have six legs (when fully grown).
The body of an insect is made up of three parts.
( head - thorax - abdomen )
Each insect has one pair of antennae or feelers.
The feelers help the insect find food.
They have their "skeletons" on the outside (like a shell).
Insects have one or two pairs of wings.
Insects are cold-blooded.
They have no lungs, but small openings on their bodies.
Insects lay many eggs.
Most insects go through a life cycle called metamorphosis.
(egg, larva, pupa, adult). The "baby" insect does not look at all like the
adult insect.
Some insects go through only three changes (like the grasshopper).
NOTE: A spider is not an insect. Spiders have 8 legs.
The spider has two parts to its body and no antennae.
MAMMALS
Mammals are the most intelligent creatures on earth. They learn to adapt
to many different climates and living conditions. Some mammals are tame,
some are wild, some are very large and some are small.
MAMMALS are alike in these ways:







They have fur or hair.
The babies drink milk from their mother's bodies.
They have a backbone.
They have four limbs (arms, legs, flippers).
They are warm-blooded. (Warm-blooded means that their bodies
stay at almost the same temperature all the time.)
Most mammals are born alive.
They breathe air through lungs.
note: Most baby mammals grow inside their mother and are born alive.
There are a few mammals that grow inside an egg in their mother's body.
Bears, apes, wolves, the hippopotamus, rodents (rabbit, gopher, chipmunk
), lions, tigers, whales, dolphins and people are all MAMMALS.
Some unique mammals are whales and dolphins, bats, the armadillo and the
platypus.
REPTILES
Snakes, lizards, turtles, tortoises, alligators and crocodiles are REPTILES.
The dinosaurs of prehistoric time were reptiles.
Reptiles are alike in the following ways:







They have dry, scaly skin.
They have short legs or no legs at all.
They breathe with lungs.
They are cold-blooded.
Reptiles are vertebrates -- they have backbones.
Most young reptiles hatch from eggs, but not all do.
Many snakes have live babies.
Young reptiles look like their parents.

Some reptiles do not have legs (snakes).
Many reptiles have claws on their feet.
Reptiles that live in cold climates hibernate in winter.
Most reptiles shed their skin as they grow.
Reptiles do not eat as often as warm-blooded animals.
Reptiles are all cold-blooded. When it is cold their bodies and blood
become cold. When they lie in the warm sun their bodies and blood
become warm.
