Let’s learn about insects!
What is an insect?
We find insects everywhere! All over the world, in every
country, in every town, there are insects.
There are even insects that can survive in Antarctica and
Greenland where it is really cold all year round!
There are insects right outside your house, in your
gardens, down the streets…maybe even a couple of
cheeky insects have crept into your house at some point!
In fact insects make up 90% of all the animals on earth!
Before we learn more about insects, set a two-minute
timer and see how many different sorts of insects you
think you know. You could draw them or write them down.
At the end we will see if all of the creatures you have
drawn can be classified as true insects.
So what makes an insect, an insect?
We will need to know some key vocabulary to talk about insects. When we use
these words again in the PowerPoint they will be in bold and underlined like
this. You can always scroll back to this screen if you need to check what the
word means.
Antennae – these are feelers on top of an insect’s head
Invertebrate – this means an animal without a backbone (without a spine)
Exoskeleton – a hard shell (like a skeleton) but on the outside of the insect’s body
Thorax – the middle part of an insect’s body
Abdomen – the last part of an insect’s body
So what makes an insect, an insect?
This wasp’s exoskeleton is black and
yellow. Insects do not have bones
like we do. They have a hard shell on
the outside.
It is an invertebrate because it has
no bones inside, not even a spine!
So what makes an insect, an insect?All insects have 6 legs. Can you spot them?
What colour are they? A wasp uses its
colours as a warning to other animals
telling them to stay away.
All insects have antennae which are used
to feel, smell and taste. Can you find
them on both pictures?
All insects come from eggs and do not look
like adults to begin with. They begin as a
larva or pupa and then change into an
adult
So what makes an insect, an insect?
All insects have three parts to their bodies. We
call this a segmented body (meaning it is made
up of different parts, like an orange).
The three parts of an insect’s segmented body
are called:
- The head where the mouth parts are located.
- The thorax where the muscles are for its legs
and wings
- The abdomen where the insect’s organs are
located.
Not all insects will have wings but many of
them do.
Can you find all the different body parts?
Have a look at this beetle. Did you
know 50% of all insects are beetles?
Can you find…
- The head?
- The thorax?
- The abdomen?
- All six legs?
- The antennae?
- Its exoskeleton?
Look back at your list you made earlier. Are all of
your animals insects? How could you find out?
So, which creatures are really insects?

Watch the video in the link above to find out more about which creatures are
really insects.
Remember, not all the creepy crawlies we are used to seeing in our gardens or in
the woods will be insects.
See if you can remember some of the things that all insects need to have…
Which of these do you think is an insect?
Make a prediction…
Answer time!I am not an insect. I have too
many legs and no antennae.
I am not an insect. I have too
many legs and too many body
segments.I am not an insect. I have too
many legs and too many body
segments.
I am an insect. I have 6 legs, 2
antennae and my 3 segments to
my body.

Bug sorting!
On the next slide you will see some
pictures of different creepy crawlies.
Lots of them you will find in a garden
or in the woods but not all of them are
insects.
You will need to look carefully and be
insect detectives to find the ones which
are truly insects.
When you think you have found them,
create a table to show your results. It
might look like this…
Or you could draw pictures of each creature
instead of writing the words.
Bugs to sort:

Extension: Go for a walk and see what other
creatures you can find. Are they insects? How
would you know?
