Science KS2 / KS3: Classification of organisms

How do we know a fish is a fish? This clip summarises how we classify animals into groups based on shared characteristics and the work of Carl Linnaeus.

Using stunning wildlife film and simple graphics, we take a journey through the animal kingdom discussing how we know a fish is a fish, even though they can all look different.

We move on to look at reptiles, amphibians, birds and mammals. But some animals, such as dolphins, don’t always go into a group that we would expect.

This clip is from the series Life Lessons.

Teacher Notes

Pause the clip at the graphics to discuss the characteristics of the group shown.

Pupils could be asked to identify further animals that share those characteristics.

Discuss if there are any further classifications not covered in the clip.

Pupils could complete an activity on grouping other objects based on shared characteristics.

When you get to the section about the dolphin, pause and ask pupils to try and classify it before the answer is given at the end.

Curriculum Notes

This clip will be relevant for teaching science at Key Stage 2 and Key Stage 3 in England, Wales and Northern Ireland or Second/Third Level in Scotland.
