Free Homeschool Unit Studies:
Ocean Creatures

Our free homeschool unit studies bring water and ocean creatures together to make an irresistible combination for any kids aged 5-7 – so long as you don't mind the bathroom getting wet!

* Free lesson plans for all ages.

* Free Action Pack with printable sea creatures you can color in.

Like all our free homeschool unit studies, you will actually cover a whole range of learning 'targets.'

Depending on where your child's interest take you, you'll cover science, geography, art and craft and reading - all in one go!

Teaching children is easy when you get them on your side. We love this ocean creatures project.

"Just want to give a great big shout out THANK YOU for the Ocean Unit Study....I wish I could hug you right now because you just made this overwhelmed mama's morning!" ~ Jennifer

This is a great project to combine with making an Ocean Diorama.

The free Action Pack has coloring pages of sea creatures which you can color in and add to your ocean unit studies, as well as beautiful photos of sea creatures.

You can get your free Action Pack on this page and use it to make a wonderful Ocean Scene.

So, where do you start?

With your child, of course! You have to go where your child's interest is and adapt this ocean creatures homeschool Unit Study to them.

First, we took the largest sheet of poster cardstock we could buy. BIG is always best with small children. Wallpaper lining paper would be great.

As you can see, we've painted the waves on the card and then got messy sticking our fingers in paint to make white fingerprint 'wave crests.'

We've used crinkly shredded paper to make homeschooling seaweed and cut out a big blue whale which the children have drawn on.


How about going down to the beach – there's lots of free homeschooling stuff just waiting on the tide line to be collected!

Ocean Creatures

Sequins make great eyes for an octopus:


Or you could put them on fish and add some flower shapes and gold barring for scales:

yellow fish with flowery scale

You'll see from my affordable homeschooling advice, there is one area I don't think you should skimp on. Top quality craft materials are a must for homeschool unit studies or any other projects you work on, like our model solar system.

Ocean creatures look good in felt too! Here's a hammerhead shark:

Homeschooling Unit Studies Activities

Free Lesson Plans

Smithsonian Institute Ocean Portal

The Smithsonian Education Ocean Portal is a fantastic learning resource which you can use to back up your homeschool Unit Studies.

You'll find:

  • Lesson Plans, including an introduction to Coral Reefs (grades 3-5, 6-8)
  • An Activity Book
  • More complex issues for older kids like a lesson where students investigate the relationship between the size of the wave and depth to which the effects of its energy can be observed.  (Grades 6-8 covering Earth Science and Physical Science)
ocean education
  • National Geographic is also great for all ages.  Find great facts, photos and videos of ocean creatures from the bottlenose dolphin to sharks and emperor penguins.
  • It also has a great photo gallery of deep sea creatures. 
  • It has activities like making your own waves and the Earth's water cycle.  Highly recommended.

Fantastic Ocean Facts

This wonderful animation helps bring your homeschool Unit Studies alive with fascinating ocean facts:

  • The oceans harbor 99% of all living space on Earth
  • The oceans have enough water to fill a bathtub that is 685 miles long on each side
  • Scientists think there are 1,000s of undiscovered species living in the deep




Great fun and learning at Octonauts corner.

You can also watch Octonauts on the BBC.

"Although Octonauts is aimed at preschool/ infant aged children we found the knowledge involved in the program was far above this and we found as adults we were learning things.

There are games on there too and coloring pages too."

~ Sheila

"I remember having fun reading an Eric Carle book about a hermit crab and making a picture of the crab by gluing on all sorts of decorations like the crab did on his journey.

Another fun picture book is called Flotsam." ~ Lisa

Endless Ocean

Janet from my Courageous Homeschooling Facebook group has suggested a lovely game you can play exploring the oceans.  There are two versions, one for slightly older children and one for younger ones.

Endless ocean

"I took these of my son playing Endless Ocean 2 on his time off the other week and thought you might like to see them, I think it's a wonderful, realistic and detailed game....It's very educational as the animals are shown in great detail in their natural environments and there are descriptions of each species, from whales and herring to goblin sharks, giant squid and angler fish.

There is a cast of characters, a story line and boats to dive from into some of the world's oceans and rivers."

~ Janet

"Thanks for sharing this Janet. I have just ordered Endless Oceans (the first edition), which says it is suitable for age 3+ x"

Help Save Ocean Creatures

If you want a fantastic way to inspire your kids to start this homeschooling unit study, watch this true home video of the rescue of a humpback whale from fishing nets. It's so amazing; the whale even comes back to say thanks!

Art And Craft


Kids love drawing! What a shame so many of them get put off by school…

  • Ocean Creatures stencils are fun.
  • How to Draw Sharks and other Sea Creatures helped us with outline shapes.
  • You can get stamps of ocean creatures to use with ink stamp pads and leave impressions of killer whales, dolphins and seals all over the place!
  • Pasta shapes, red lentils and kidney beans make an unusual free shark collage.
  • I love this seahorse diorama.  It's just some seahorses hanging from cotton thread in a box..but fabulous nonetheless!

  • Shirley tells you how to make some great sparkly pink and yellow sea anemones using toilet rolls and plastic bags in her page on sea anemone craft.

  • Origami is fun. You can easily make a homeschooling origami whale, either by following instructions from a book or by getting an origami Ocean Creatures World kit. We added a silver foil shiny spout and a stick-on eye.
  • Watching David Attenborough's The Blue Planet got us fascinated with ocean creatures like Anglerfish and how they attract their prey.

  • We enjoyed Free Willy too. My homeschooling diary from October records that we spent the whole of one day with everyone being whales – krill for lunch - hmm!

"My son's currently sat watching Blue Planet for about the 10th time." ~ Steph

Set Up An Aquarium

Setting up an aquarium can be a huge excitement - and a great addition to your homeschool Unit Studies.

You can go for a real aquarium like Mandy:

enjoy your own aquarium

"Our new fish tank minus the fish.  My kids have already named their new pets even though we don't have them yet haha." ~ Mandy

If you are thinking of doing the same, Simone can help you make sure you don't make a mistake I wouldn't have thought of:

"Such a fun hobby (and quite addictive!)...I would recommend watching some videos on youtube about the cycling process. It can take weeks to build up the beneficial bacteria. You can cheat by using some used filter media from an established aquarium (if you know a friend who has a tank?) or even adding a bacteria starter which you can buy from the pet store...I learned the hard way and nearly lost all my fish yikes!" ~ Simone

Or you can go virtual!

  • Create your own aquarium complete with sea creatures at this National Geographic site. Design your own custom tank and share with your friends - no cleaning required!

Science Experiments

What an ideal way to add water into the equation and learn all sorts of free homeschooling science!

  • You can fill your bath full of ocean creatures and play the game: Does it float or does it sink? ("Properties of materials" for those who do teacher-speak homeschool unit studies).

  • If you squeeze the bubbles out of a sponge, you'll be able to work out why 'floaters' sink too.
  • You can make metal ships out of tin foil, divide the inside into cargo holds with bits of cardboard and work out how load effects which end sinks first. (Physics for free as part of homeschool unit studies.)

Field Trips

This is a must activity to get the most out of your homeschooling unit studies.

  • The London Aquarium left us with memories of glass catfish, a sleeping leopard shark and feeding manta rays.
  • We met Bruce, the black-tipped reef shark, on a homeschooling trip to a Sea Life Sanctuary.

Ocean Crafts

If you've got a child who likes making models, you've got an ideal way of adding design and technology to your ocean creatures homeschooling unit studies.

  • We used K-Nex to make a 94cm shark.
  • We made a free homeschooling submersible out of a cereal packet body with cardboard egg box lights and a vegetable net fish-catcher.
