Under the Sea themed activities – Early Years

One of the things I love the most about Science Sparks is theming our activities, so today I’ve got some great Under the Sea themed learning ideas to share, mostly suitable for Early Years/Kindergarten age, but all could be extended for older children.

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



Extension ideas

  • 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.

We love this small world ocean theme from Rainy Day Mum.


Red Ted Art has a super cute octopus made from tights.

How gorgeous is this  under the sea playdough from The Imagination Tree?


Paint an under the sea themed picture on ice ( fun for summer or winter )

Try some ice fishing.

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



Crack the code in the shells to find a hidden message.

Make a shoe box ocean scene, 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 props for inspiration.



Other ideas

Make a Rainbow fish with lots of silver foil scales? Children can then practice sharing the scales evenly between the fish.
