one short film showing ocean life
one short film investigating the impact of pollution in the deep sea
three activities to build on your knowledge
Oceans of the world
There are five oceans in the world. Together they cover more than 70 per cent of our planet, and they are all connected together. The oceans are:
- the Atlantic Ocean
- the Pacific Ocean
- the Indian Ocean
- the Southern Ocean
- the Arctic Ocean
The nearest ocean to the UK is the Atlantic Ocean. It stretches from Europe to North and South America, and is the second largest of the five oceans.
Sue Venir is on a beach by the Atlantic Ocean. Watch this short animation to find out more about oceans!
What are ocean currents?
The water in the oceans is constantly moving in patterns called currents. Some currents flow quickly, while some move very slowly. As the currents flow around the planet they move cold and warm water from one place to another, changing climate and temperatures all over the world. The UK would be much colder if it wasn’t warmed by water that travels all the way from the Caribbean, in a current called the North Atlantic Drift.
The ocean currents also help move anything that floats in them. This can be sea creatures or ships, but unfortunately it also carries rubbish that has been dumped carelessly by people. This rubbish finds its way around the world, pollutes the oceans and can be harmful to sea life. Some kinds of rubbish, such as plastic, are eaten by sea creatures. This causes them lots of problems and can even kill them.
We need to look after our planet by recycling and reducing the plastics we use.
Watch this short film to see some incredible ocean life in action.
Watch this short film from the BBC series, Blue Planet Live, in which Marine Biologist Diva Amon investigates the human impact of pollution in the deep sea, and how deep sea mining is threatening to destroy valuable habitats.
There are lots of fun things to do to help you remember what you've learnt about oceans.
Here are a few you could try.

Blue Planet: Live lesson
Guided by CBBC's Naomi Wilkinson and expert wildlife biologist Lizzie Daly, we explore what constitutes a healthy ecosystem and discuss the threats to our oceans such as plastics and overfishing.
