Fun ocean science activities are a perfect way to spend time at the beach or prepare for a trip to the ocean! We have tons of fun ideas for when you are on the beach and also when you are home learning about the ocean. Science activities are a wonderful addition to summer ocean fun. Time at the beach is all about discovering, exploring, and observing the wonderful things the beach and ocean have to offer.
Ocean Science Activities for Kids
Learn About The Ocean Through Hands On Sensory Play.
We love visiting the ocean and have the good fortune to be able to go several times a year! Liam’s first visit to the beach was at 9 months old! Last year we did a few early learning activities to prepare for our trip to the beach and this year we are trying a few more. Each year we learn a bit more and explore a bit more and will add to our ocean science activities.
Have you seen our ocean slime?

1. Ocean science: Beach Treasure Hunt Ice Tower
It’s easier than you might think! I used a milk carton and cut off the top so I was left with a rectangular box with an open end. Last weekend we went to the beach for a family day! I thought it would be fun to collect items from the beach and bring them home to make one of our favorite icy experiments! We found shells, rocks, sea glass and various kinds of seaweed! We even put some beach sand in a pail to add to the bottom. For the first layer of the milk carton I added the sand, some shells and water. Once frozen, I repeated the process in small layers until I filled the container. Sand was only in the bottom layer. Use squeeze bottle, eye droppers, and scoops to help melt the ice and dig out the treasure!
Adding sand to the first layer made for a fun discovery as the ice melted and the end result was a great ocean scene!
2. Ocean Waves Ocean Science Sensory Bottle
We have done several versions of oil and water experiments this past year. This is a very simple and quick experiment to demonstrate waves! I saw this here: Entropy Kitchen, Ocean In A Bottle. I love the look of mineral oil but the vegetable oil worked just fine. We gently moved it back and forth to make waves. I added a few shells too!
3. Ocean science: Fizzy Baking Soda Ocean Science Sensory Play
Fizzy baking soda science is always fun. I simply buried shells and a few plastic starfish under baking soda. I gave him little bowls of yellow, green and blue colored vinegar and an eye dropper to color his own ocean and find the sea life! He loves the bubbling fizzing action and then enjoyed burying the sea life.
4. Ocean science: Salt Water / Fresh Water Seashell Float Or Sink
We have done this before with an egg and super heroes but I wanted to try it again so we could talk about how an ocean is made up of salt water. We talked about how we drink fresh water but some animals live in salt water and use water differently than we do. We named animals like seals, sea lions, dolphins, whales and fish. Of course, we used our super heroes to experiment too.
Set Up: You need two bowls and two sets of similar objects. I picked some shells. I added a 1/2 cup of salt to about a cup and a half of hot water. The other bowl I filled with tap water. Mix well and experiment. Check out other salt water experiment for more information.
5. Ocean Science: Examine & Explore The Textures And Smells Of The Ocean
What remained from our ocean ice tower, was a beautiful representation of the ocean. We had our own little touch pool! I laid out a tray, tongs and a magnifying glass so we could look at, examine, feel and even smell our beach finds!
6. Ocean Science: Pollution And Recycling Sensory Play Activity
We did this simple ocean science sensory play activity to learn about recycling, what can be recycled and ocean pollution for Earth Day. It was awesome play and a great learning experience for both of us! He has really gotten into recycling this year and knows so much more about it now.
Easy Ocean Science Experiments and Activities for Kids!
I can’t wait to get to the beach this year and talk even more about what we have learned! We plan to take a hands on discovery cruise out of Woods Hole this year. Lots of walks on the beach too. Summer time is a wonderful opportunity for ocean science activities. No trip to the beach planned? Shells from the craft store, natural colored sand, and seaweed from the specialty food store will do the trick!
The beach is an awesome place to learn!
