Intro to Oceans

This learning block represents one week’s work. Aim to watch at least one video and choose at least one activity or project to complete. 

There are two videos to choose from about oceans. The first one is better for younger kids, the second one will appeal to older kids. Feel free to watch one, or both!

Now choose an Activity

ocean density experiment

Have you ever been to the ocean and noticed that it’s much easier to float in salt water? Why is that?


Do an experiment with an egg that demonstrates the difference in density between saltwater and freshwater.

If you have time after you float the egg, test other household objects. Make note of which ones float in saltwater vs. freshwater. Test lots of things!

Talk about what you discover.

Take a picture or video of the experiment for your portfolio!

explore how waves form

Watch the above video about how waves are formed and what causes them.

If you are really interested, continue with this video about how tsunamis form.

Next, make a wave bottle so that you can play with waves yourself! Be sure to talk about the density difference between oil and water which explains why the wave bottle works!

Ocean Zones Project

Step 1: Watch this video about ocean zones then, make the basics of an ocean zones poster to add to. Make the sunlight and twilight zones the biggest on your poster (because we’ll be adding the most to those sections, but be sure to point out that MOST of the volume of the ocean falls below those zones.) 

Step 2: Label the zones, and paint them in layers of blue from light blue (sunlight zone) progressively darker down to the abyss. Like this example. We’ll add the creatures we learn about to the various zones where they belong.

Step 3: Have a look at these Ocean Zone Charts and think about the layers of life in the ocean. Look at a couple of creatures that live further down in the zones.

Next, watch this video about octopus and the next one about starfish:

 Then, make an octopus, or a starfish, or both to add to your Ocean Zone poster.
For the octopus: simply print, cut out and colour this octopus head. Next, cut eight strips narrow of construction paper. Glue one end of the each strip to the back of the head. Then, roll each strip starting at the non-glued end, towards the head around a pencil, curling each leg.

For the starfish: simply draw a starfish shape on the paper backing of a piece of sandpaper. Cut it out. Colour the front with crayons to bring your starfish to life.

Glue them into the appropriate ocean zone (hint, LOWER than the fish that you created earlier!)

Step 4: Watch this video for kids about the Mariana Trench, then, watch this video about Angler Fish. Then, draw an angler fish to add to your Oceans Zones poster… you can draw a sea cucumber too, or the other deep sea creatures you learned about!
