What does classification mean? Why is it
important?
Individual, pair and share
First, answer this question on
your own and then discuss it

The Classification System
All living things are classified into five main groups called
kingdoms.
living things
plants
animals
fungi
Bacteria
(prokaryotes)
Protoctists
Most living things belong to the animal kingdom or the plant
kingdom.

Success criteria
1. I can state what is meant by the term classification.
2. I can describe the difference between invertebrates and
vertebrates and their subdivisions using examples.
Which group do I belong to?
Boys vs. Girls.
One boy and one girl will go head to
head in the ‘Which group do I
belong?’ to game show!
I will read out a number of clues; when you think you know
which group the animal (vertebrate) belongs to, you must call
out your buzzer noise!
Girls – bang!
Boys – pop!
Then the whole class will be asked a question.
Then, we start again with a different boy and girl.
Which group do I belong to?
1. I live mainly in water.

Plant classification
Mosses: They have simple leaves and shallow roots, with no proper
vascular systems. The leaves are very small and are not covered
with a waterproof, waxy cuticle layer. Mosses, Angiosperm and Lichen
are often found in damp areas as they dry out easily. They reproduce
using spores.
Ferns: They have proper roots and stems, and leaf-like fronds. The
leaves are not covered in a waterproof, waxy cuticle layer and so they
dry out easily and are generally found in damp places. They do have a
vascular system. They reproduce using spores.
Conifers: They have vascular tissues. They are large plants with
proper roots and stems and needle-shaped leaves with a waxy cuticle.
They are good at surviving in dry or cold climates. They reproduce
using seeds found in cones.
Flowering Plants: They have vascular tissues. They have proper
roots and stems and have flowers. Their leaves are large and flat and
have a waxy cuticle. They reproduce using seeds found in fruits.
