Learn Some Facts About Sea Creatures.

First, sing and dance along to this clip about sea creatures:


Then, watch this 4 min clip to learn some facts about sea creatures:

Look at this

Finally, draw a picture of some of the sea creatures that you have learnt about today and write 1 or 2 facts about them.

Design and Make Your Own Sea Creature.

First draw your design. Will your creature have a tail or tentacles or pincers, sharp teeth or maybe fins…?

Then write labels to show which materials you will use to make each feature.

Finally, follow your design to make your sea ceature.

Science Investigation: Floating and sinking

First, watch this 5 min clip to find out about floating and sinking:   floating-and-sinking

Then, ask your grown-up to help you find some things that you can test to see if they float or sink in water.  Make a prediction before you test each one.

Finally, think about which materials the objects were made from (wood, plastic, metal…). Does the shape of the object or type of material affect if it will float or sink?

Create a Boat that will Float

First, watch this 2 min clip to help you think about which materials you could use to make a boat. Think about what you discovered about materials yesterday too: .why-do-things-sink-and-float

Then, make a little boat.(It does not have to be made out of wood.)    You could make a sail or flag for it.

Finally, ask your grown-up if you can test your boat to see if it will float.

Create an Aquarium Picture

First, draw and colour some sea creatures and carefully cut them out below.

Then, ask your grown-up to cut out the centre of a paper plate or draw a white circle and cut out the centre.

Finally, attach cotton or string to each picture and hang them inside the circle to create your aquarium like the picture:

Wonderful Underwater World

Take a look at our world’s amazing oceans!  

Take a look here

Learn about the different layers of the ocean:

Find out about one sea creature from each of the layers in the ocean:

Sunlight Zone

Twilight Zone

Midnight Zone

The Abyss

The Trenches

How big are they? What do they eat? How do they find food?

Choose an interesting way to display the information that you find out!

Click here for worksheet.


The octopus is said to be one of the smartest sea creatures.

Watch the following video clips about an amazing problem solving octopus.

Now create your own octopus escape room using boxes, tubes and any other junk modelling resources that you have at home.

Remember that they are very intelligent and can solve problems with more than one-step!

Click here for worksheet.


You might even like to write a set of instructions explaining how to escape your escape room!

Floating and Sinking

Using a container of water, find out which materials float and which sink.

(Make sure that you have your adult’s permission first!)

Make a boat out of a material that floats.


How many 1p coins can it hold without sinking?

Boat Challenge

Research one of these famous shipwrecks and make notes.

Here are some links:

Click here to see information about the Titanic.

Click  the link below to find out about the Mary Rose: tudors

Where was it travelling from and to when it sank?

  • How many people were aboard the ship?
  • When did it sink?
  • Where did it sink?
  • Why did it sink?
  • Is the ship still on the seabed?

Then, pretend that you are a news reporter telling the world about the sinking of the Titanic or the Mary Rose.

Click here for worksheet.

You could ask an adult to record it and send it into school for your teacher to see.

Underworld Creation

Using your favourite underwater creatures, create an underwater world.

Wonderful Underwater World

Find out about the wonderful underwater world, which exists in our planet’s fascinating oceans.

Make a page that includes fascinating facts that amaze you about our world’s oceans.

Layers PowerPoint

Use the videos below to help develop your knowledge about our amazing oceans.

How do sea creatures survive in their underwater environment?

Using the PowerPoint from yesterday, recap on the different types of creatures that live at different levels. They all have adapted to their unique environment.

Can you create your own underwater creature – describe how your creature survives in its environment. You could make a poster, model or be creative. Which level of the sea can it be found? Is it able to use camouflage to hide from predators? Can it re-grow limbs? Does it have claws to defend itself?

Use the clips below to help you understand how sea creatures have adapted to their underwater world.

Find out how sea creatures are adapted to life in water

Find out about how creatures survive in rock pools.

Floating and Sinking.

Can you investigate which objects float and sink and find out why?

Plan your investigation carefully, try to ensure it is a fair test. Use the website below to find out more about floating and sinking, buoyancy and the force up thrust.

Boat Challenge

Can you make a boat that will still float when it carries a weight? Try placing it in the water and see how much weight it can hold. Can you amend and alter your design to give it greater buoyancy? What is the best design you can make? Draw a picture of your boat and show how you have adapted it to improve buoyancy. You could investigate whether different materials make better boats or whether the size and shape makes a difference to its buoyancy?

Take your Pick – Use your imagination

Choose an activity about an Underwater World.

You could find out about The Mary Rose, an impressive Tudor ship that sank off the coast of Portsmouth.

Design an underwater world – you could find out about the Lost City of Atlantis for inspiration.

Create an underwater scene based on your learning – you could draw a picture, make a collage or create a shoebox scene.

Make a news report about the Oceans and how to protect them from plastic pollution.

Present a ‘documentary style’ report about the layers of the ocean.

Find out more about some of the amazing sea creatures living off the British Coast.
