Ocean-Themed Sensory Play for Young Children

Published on 01/06/2026 in Early Years

There’s something about the ocean that naturally draws children in, whether it’s the feel of sand between their fingers, the sound of water, or the excitement of finding a hidden shell. Even when you’re nowhere near the coast, you can still bring that same sense of discovery into everyday play.

With just a few simple materials, you can create calm, hands-on activities that let children explore, imagine, and learn at their own pace.

Why ocean sensory play is great

Playing with sand, water, and natural items gives children the chance to explore using their hands and senses. They can scoop, pour, dig, and feel different textures.

You’ll often find that children start chatting about what they’re doing as they play, which helps build their language too. And because these activities are open-ended, there’s no right or wrong way to play.

Ways to try Ocean-Themed play

Make a sensory tray rock pool to explore

Add sand and a little water to a tray, then pop in some shells and small sea creatures. Children can dig, splash, and discover hidden items.

Set up a small fish aquarium

Fill a bowl with water and add toy fish. It’s simple, but children love moving things around and making up little stories. We added these realistic Fish Sensory Stones

Fish Aquarium

Shells Mandalas

Lay out shells and pebbles and let children make their own shapes and patterns. It’s a nice calm activity.

Explore Sealife in a sand tray

Hide objects in the sand for children to find or press items into it to make marks. You can swap sand for playdough for a different feel.

Discover the Big Blue discovery table

We love this book from Yuval Zimmer. Discover and read about the oceans and what lives within them in this wonderful book.

We added beach treasures, shells, rocks, fishing rope, driftwood and wooden boats to our discovery table.

Encourage conversations around looking after the oceans and keeping them free from litter.

Big Book of Blue

Try sorting and counting

Use shells to sort by size or shape or count them out. It’s a simple way to bring learning into play.

Counting Shells

Make clay creations

Use air dry clay and press shells into it to make patterns. Once it’s dry, children can paint what they’ve made.

Sea Life Decorations

Decorate shells

Let children paint or stick bits of paper onto larger shells to decorate them.

Set up a tinker tray

Fill a tray with different ocean items and let children explore however they like. No rules, just play.

Add letters to the sand

Pop some letters into sand play so children can find them, trace them, or spell simple words.

Keeping it simple

These activities don’t need much setup, and you can use what you already have. The main aim is to give children time to explore at their own pace.

Sometimes the simplest play ideas are the ones children enjoy the most!
