Preschool Ocean Theme Activities

There’s something about the ocean that makes it so mesmerizing. Maybe it’s the size. Maybe it’s all of the different creatures that can be found in it. Either way kids really enjoy learning about the ocean and sea life, so a preschool ocean theme can  be a treasure trove of new discoveries and learning.

Here are some fabulous resources for planning your preschool ocean theme activities.

Preschool Ocean Theme Activities...the ultimate resource full of activity ideas, preschool lesson plans, songs, nonfiction videos and more for teaching young kids about the ocean

Why It’s Fun

There’s so much to learn with an ocean theme. Kids have so many questions about the ocean that it can lead to a very long unit study as you let their curiosity lead the way. Even if kids can’t actually visit an ocean they enjoy imagining what it would be like and engaging in ocean inspired pretend play. Nonfiction lovers are thrilled to learn new facts about sea creatures, and there are tons of opportunities for sensory exploration in this theme.

When to Teach a Fish Theme

An ocean theme can be taught any time of year. It can be a separate theme, or you can combine it with another focus like the beach, specific sea creatures, or different kinds of bodies of water.

As you approach the end of the school year an ocean theme can also be a natural way to lead into summer, or it can be a theme you explore during the summer if you teach year round.

Teaching Tips & Major Concepts Kids Will Learn

If you’re planning a preschool ocean theme there are so many possibilities for incorporating meaningful early learning skills.

These are just some of the concepts kids can learn about the ocean:

  • where oceans are found on Earth
  • what kind of water is in the ocean (and the properties of saltwater)
  • different layers of the ocean
  • specific animals that live in the ocean
  • jobs people have related to the ocean (fisherman, oceanographer, marine biologist, etc)
  • how far your hometown is from the nearest ocean

You can also use small sea life manipulatives for many learning activities to teach math and literacy concepts.

Items to Collect and Request in Advance

If you get parents, friends, and family involved you can enrich the experience kids have during your preschool fish theme.

Collect or ask people to help you collect:

  • artifacts from the ocean (sea stars, shark teeth, sand dollars)
  • photos from trips to the ocean
  • ocean related tools for pretend play (toy fishing rod, pretend tropical fish, snorkeling gear, flippers, binoculars)
  • magazines with photos of sea life

You might even invite special guests (or go visit if you can) to come and share about fields and hobbies related to fish. You could include:

  • a fisherman (hobby or professional)
  • a seashell collector
  • a marine biologist
