Under the Sea Themed Activity Ideas for Early Years

Under the Sea Sensory Jar

Make an Under the Sea themed sensory jar. This is quite a large example, but you could use small water bottles and make lots of mini sensory bottles.

What can you do with a sensory jar?

What happens if the jar is put on one side? Try simulating the motion of waves.How many shells can be counted on the bottom?Ask children to find an object which will float on the top of the oil?Try hiding some plastic letters to spell out a word.Think about why the oil floats on top of the water. This is because oil is less dense than water.

Try some ice fishing. This is a brilliant activity for learning about freezing and melting!

Learn about pollution with our ocean themed jar, again you could do this on a much smaller scale than our large container.

Crack the code in the shells to find a hidden message. This is a great first coding activity for young children.

Make a shoe box ocean scene. This is a great prop for talking about what you’d expect to see in the ocean ( I can’t take credit for this as my daughter made it in school ), but we did add a moving fish to the side and have been making up stories using little extras for inspiration.

More ocean themed activities for kids

Ask some questions. Why is the ocean blue? is a good place to start!

Find out what would happen if the ice caps melted with this very visual demonstration.

Ocean Themed Book Suggestions

Our current favourite book for an ocean topic is What a Shell Can Tell. This is a fascinating book about the wonders of shells. The question and answer format makes the book easy to dip in and out of and really showcases the huge diversity of shells around the world! Did you know that there is a type of shell shaped like a little elephant’s tusk?

We also love Tiddler and Rainbow Fish!
