World Ocean Day 2023 - 10 Creative & Engaging Ocean Crafts Activities for Preschoolers & Kids

10 Fabulous Ocean Crafts for Preschoolers and Kids

World Ocean Day is a day when kids get to learn about their friends living under the sea. Ocean crafts and activities are a terrific way to engage with your kids and teach them the wonders of the sea. And we’ve got plenty of activities to boot.

Beautiful and Creative Ocean Craft for Children

You don’t need a lot of supplies for these activities. Just a bit of creativity and a willingness to have fun. Your kids can follow along but you take charge when it comes to handling the glueing and cutting with the scissors.

1. Cute Pufferfish Craft

When it comes to ocean theme crafts for preschoolers, Pufferfish paper plates take the cake. They are very easy to make and require a few simple household supplies.


  • White paper plates
  • Tempera paint
  • Paintbrushes
  • Cotton swabs (Q-tips)
  • Scissors
  • Glue
  • Colored construction paper scraps
  • Markers or crayons

How To Make:

  • Start out by painting the white paper plates with your favorite tempura paint for the body of the Pufferfish. You can get creative with this step and use a variety of colors and shades.
  • Dip your cotton swabs in a different color of paint and make spots for the body of the Pufferfish using the Q-tips. You should get a dotted patterning.
  • Make slits around the edges of your paper plate using the scissors and remove any tabs between them. There should be spacing between the spines. Trim the spines further and refine them.
  • Get your colored construction paper out or use construction paper scraps for the next step. What you want to do now is make cutouts of the construction paper to make the two fins and glue that to the Pufferfish’s body.
  • Use white paper to cut out two eyes and a black marker to fill in the iris. Glue that to the plates and draw a smile below the eyes to complete the Pufferfish’s face. Your beautiful Pufferfish paper plates are now ready to be showed off!

2. Fun Ocean Slime

  • Pudding cup

How to Make:

  • On a tray, place a pudding cup upside down. Press it firmly from the top and start painting the body. You can use bottle caps to pour the paints and mix color combinations.
  • Rotate the tray and keep painting so that you can let the other parts of the cup dry out and not get affected.
  • Make a cutout from the foam sheet and glue it to the top of your cup.

7. Recycled Foam Fish

You can use recycled chair foam to give an interesting sensory experience to your kids. Foam fishes are a favorite activity to do among ocean crafts for toddlers and preschoolers.


  • Chair foam
  • Onion mesh bag
  • Chenille stems
  • Scissors
  • Glue
  • Googly eyes

How to Make:

  • Cut out the chair foam in a fish shape. Make sure the size of your shape is smaller than an onion mesh bag. You’ll be using the mesh bag for creating the fins and body patterning.
  • Fit the fish foam into the mesh bag and secure it snuggly. Use the excess part of the mesh bag to twist and create the tail. Secure the tail by using a chenille stem and twisting it tightly in place.
  • Add the googly eyes to the front of the foam body and use glue to stick it in place. Cut out a piece of the mesh bag and attach it to the body with glue to make the fin.
  • Your foam fish is done!

8. Friendly Crab

You can make a friendly crab using a simple egg carton. You will be surprised by how easy it is to make.


  • One egg carton (empty)
  • Acrylic paints
  • Paintbrush
  • Pipe cleaners
  • Craft glue
  • Googly eyes
  • Scissors

How to Make:

  • Cut one cup out from the empty egg carton. You are going to make the crab’s body out of this which is why you want to make sure you get the cut precise. You can use a craft knife for this step.
  • Trim the edges and paint the egg cup in a brick red color. Paint both the inside and outside and set the egg cup aside to let the paint dry.
  • Get eight pipe cleaners (2-inches length) for the legs, 2 cuts for the claws (4 to 6 inches of length), and two more cuts for making the eyes bulge out (half-inch here).
  • Attach the legs to the crab’s body using glue and place them with symmetrical spacing.
  • Twist the shorter lengths for the claws and curl into a Y-shape. Attach that with glue near the bottom front of the body.
  • For the shortest pipe cleaner cut (1/2-inch), put a glue dot to the back of the googly eyes and stick it with the ½ inch pipe cleaner. Add that to the top of the crab’s body using enough glue. You’re done!
