50 Ocean Themed Activities for Preschoolers

by | Jun 15, 2021

Summer is here and even if you aren’t headed to the beach the warmer weather is a good excuse to teach your preschoolers about the ocean! The ocean is so fun to teach about because there are countless plants and animals for your preschooler to learn about and identify.

I always find that with my preschoolers hands on activities are the best way to learn and everyone ends up having a great time. Not only are hands-on activities great for learning, but they are also great for teaching fine and gross motor skills, team building, sensory building and getting the kids outdoors. 

Let’s dive into some fun ocean themed activities for preschoolers!

What Should You Teach Preschoolers About the Ocean?

While you’re creating beautiful ocean masterpieces and crafting your child’s favorite sea animals, it’s a great time to give them a little lesson about the ocean. There’s so much to learn and explore that your preschooler or toddler will love hearing all the new concepts about the ocean.

When teaching about a new topic I like to focus on simple questions: Who? What? When? Where? Why? And How? This allows your preschoolers to speculate and engage in the discussion.

You can ask the following questions to see if they know or simply just teach the concepts and ask them if they remember later on:

  • Who are the animals that live there?
  • Why is the water salty?
  • What do they eat?
  • How do they breathe?
  • How do the animals move?

These are all really great questions to ask and discuss while engaging in activities with your preschoolers. I love to listen to their answers and see what they already know about the ocean.

  • Where do they sleep?
  • How much of the ocean takes up the earth?
  • What are high and low tides?
  • How can you be safe in the ocean?
  • Where do shells come from?
