Year 5: Beast Creator Week 2

Have you been on a mini-beast safari yet? If not, look at the Beast Creator Week 1 post to find out more.

This week we are focusing on this LI:

I know that there are thousands of invertebrates that can be classified into groups. I can name some of the groups.

There are some long science words in this LI so let's find out more.


Invertebrates are animals that don't have a backbone. Some have soft bodies, like worms, slugs and jellyfish. Other invertebrates, like insects, spiders and crustaceans, have a hard outer casing called an exoskeleton. This protects their body a bit like a suit of armour.

Task: Watch the clip, do the sorting activity and the quiz at bitesize here. Write a definition for invertebrate in a notebook, include examples.

What does CLASSIFIED mean?

Animals can be divided into groups or 'classified' by looking at the similarities and differences between them.

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 fish, amphibians, reptiles, birds and mammals.

There are many different groups of invertebrates too. They include invertebrates which have soft bodies such as jellyfish, worms and molluscs (like slugs and squids). There are also groups of invertebrates with hard bodies, such as insects, crustaceans and spiders.

Task: Watch the bitesize clip here and do the activity and quiz underneath it. Write an explanation for classification in your notebook, include examples.

Lastly, have a look at this photo which I took during half term when I went for a walk along the River Thames. How many different types(species) of invertebrates are in the Thames?

Can you remember from the first clip, what percent of the Earth's animals are invertebrates?

Task: Lastly, spend some time exploring at this website here to find out more about invertebrates. Write down some facts that you discover and begin to make a list of the groups are that invertebrates are classified in to. We'll find out more about the groups later in the week.

Enjoy your scientific learning,
