Once you start exploring the ocean with your kids, it won’t be long until their curiosity is soaring. Grab these free resources to explore the layers of the ocean to teach your kids about the regions of the water that cover so much of the Earth’s surface.
Since I live on an island, I can’t help but want to teach my kids all about the ocean. My kids have grown to love the ocean so much that my daughter (13) wants to pursue a career in marine biology.
The island where we live is in the Pacific Ocean, the largest ocean on Earth, covering around 30% (or 1/3) of the Earth’s surface. Pacific means Tepre Pacificum in Latin, “peaceful sea”.
It is no wonder why my daughter loves the ocean. It is peaceful, its beauty surrounds us, and we have seen its power during storms.
The ocean remains a mystery to her, to me, and every other human on Earth. Literally, every human. These stats will blow your mind.
We can see that oceans cover around 70% of the Earth’s surface. There is no doubt in studying the oceans. Your kids will ask you some questions like how big the ocean is, how deep is the ocean, etc.
Well, the incredible truth is this.
As vast as the ocean is and vital for the source of living things (70% of our oxygen comes from the ocean, NatGeoKids), a whopping 80 percent of the ocean has never been mapped, never been observed, or explored.
It is way too difficult still and way too expensive to explore the ocean in its entirety with the current underwater vehicles and sonar technology that exists today. Therefore only 10 percent of the entire global ocean waters have been mapped my sonar technologies.
Even adults are curious about what else is out there then? It boggles my mind. What sea creatures haven’t we discovered? How cool must they look, and how do they live? Are there huge sea animals out there? Could they have beautiful or even neon colors?
The National Oceanic and Atmospheric Administration (NOAA) is working to increase understanding of this ocean realm, which will remain a mystery to humankind for quite a while.
So, where do we begin our ocean unit study?
The best place to start an ocean unit study with ocean terminology and then with studying its layers – also called ocean zones. Different animals live within each layer of the ocean, so you can incorporate the animals with each layer you teach your kids.
Here is a basic overview of the five layers or zones of the ocean:
Layer 1 – The Trenches (Hadalpelagic Zone)
Layer #1 is the deepest layer of the ocean located in the basin or below. Of course, it is darker than dark, colder than cold. No light can even penetrate this layer at all.
Even though these conditions may seem impossible for creatures to thrive, some creatures live here. Mostly the animals living in the trenches are starfish and other invertebrates.
Layer 2 – The Abyss (Abyssopelagic Zone)
This layer or zone has temperatures that are near freezing, and there is no light at all. It is home to creatures, including sea stars (starfish) or squid.
Get this – 75% of the ocean floor is in this zone, the Abyss.
Layer 3 – The Midnight Zone (Bathypelagic Zone)
This layer is super cool, as some of the animals here produce their very own light. These are called bioluminescent creatures.
Many of the creatures here are either red or black due to the lack of sunlight. Whales often go hunting in the Midnight, or Dark Zone, for food.
Layer 4 – The Twilight Zone (Mesopelagic Zone)
This layer has faint sunlight and is home to cool sea creatures like the swordfish, the wolf eel, and even some bioluminescent creatures.
Layer 5 – The Sunlight Zone (Epipelagic Zone)
This is the tangible part of the ocean. It is where we can swim, where we find the coral reef, and where photosynthesis occurs.
Can you believe this is the only layer of the ocean that most of us will only ever have access to?! That is pretty amazing.
Now, let’s get some resources to teach our kids all about these mysterious layers of the ocean.

In the Ocean Notebook students learn all about life in the ocean, layers of the ocean, the ocean floor, coral reefs, tide pools, and much more.
