Begin your ocean unit study with this salt water density experiment for ocean science experiments for kindergarten. Also, grab my other tips, ideas, and crafts for kindergarten on my page Kindergarten Homeschool Curriculum.

While there are many fascinating animals, plants, and shells in the ocean there is so much more to learn about.

As a matter of fact, only 5% of the ocean has even been explored.

Quick Unit Study & Easy Salt water Density Ocean Science Experiments For Kindergarten

But beyond that for simple learning purposes there is much to cover beyond sharks, fish, and coral.

There are also the tides, ocean depth zones, and currents.

And today we are going to learn about salt water density and the effect it has on objects in it.

I have a fun but simple hands-on science experiment to learn about saltwater density.

Before we dive in, here are my suggestions for must haves for an ocean unit kindergarten to make it fun, immersive, and memorable.

Finally, let’s do a hands-on easy salt water density experiment.

Ocean Science Experiments For Kindergarten Salt Water Density

So no special supplies needed.

You will need:

3 clear cups
Salt
Warm tap water
3 raw eggs
cardstock/pen

Place 3 clear cups out, you can use plastic or glass just make sure all 3 are the same.

Add equal amounts of warm tap water in each cup.

Measure 1 Tablespoon of salt into one cup, 2 teaspoons in another, and put nothing in the third.

Stir to combine the salt into the water completely.

Make a label for each of the cups to keep them straight and place it in front.

Carefully drop an egg into each cup.

Why happens?

The egg in the cup with the most salt water floats near the top because the density of the water is greater than that of the egg.

The water with less salt water sits about halfway in the water because the density ratio of water vs. object is close.

The raw egg in plain water sinks quickly to the bottom, the reason this happens is because the egg has less density than the water.

Ask your child some questions to get them thinking – Which egg is floating?

What happened to the egg with no salt in the water? Why do you think that happened?

Today, for book Number 29 Down and Out Down Under of the Geronimo Stilton series, we’re making an edible coral reef. The Geronimo Stilton books are for ages 7 to 10 years old and are full of mouse fun and adventure.

In the Geronimo Stilton series book Down and Out Down Under, Geronimo is off to learn on adventure to Australia.

The Geronimo Stilton Series: Make a Fun Edible Coral Reef

And when you think of Australia you may immediately picture cute koalas and terrifying crocodiles but another famous and very important part of Australia is The Great Barrier Reef.

The idea for creating this fun hands-on coral reef is from our latest read which is Down and Out Down Under (Geronimo Stilton #29).

The Great Barrier Reef is one of the 7 Natural Wonders of the World and is teeming with incredible life, color, and beauty.

The story covers a lot of topics of interest in Australia.

This fun book mentions land animals, Uluru, Aborigines, topography, and the Great Barrier Reef .

Great Barrier Reef Resources

Today’s hands-on activity is fun, colorful, and a great way to teach all ages about the life that is in the Great Barrier Reef.

If you want to make an impact, hands-on activities are always the best way to fully immerse your kids into your topic.

This hands-on fun activity also appeals to all 5 senses and will make certain that your kids do not forget while they learned anytime soon.

Besides Down and Out Down Under (Geronimo Stilton #29) here are a few beautifully illustrated spines you may want to add to your library.

They are great basics that give great bites of information about the ocean, reefs, ocean animals and plants, and more.

Ocean Anatomy . I am such a big fan of the illustrations in these books but also how much information is contained in each topic. This one covers everything from why the ocean is blue and salty to tides, animal life, and even a section on The Great Barrier Reef specifically!

I am such a big fan of the illustrations in these books but also how much information is contained in each topic.

This one covers everything from why the ocean is blue and salty to tides, animal life, and even a section on The Great Barrier Reef specifically

Facts About the Great Barrier Reef

:Next, here are a few facts to share about the The Great Barrier Reef.

The Great Barrier Reef, located off of the eastern coast of Australia, is the longest coral reef in the world.
It is home to 1500 species of tropical fish and 400 finds of hard and soft coral
The reef serves as a protective habitat for many other forms of marine life.
One of the threats to reefs is coral bleaching.
Crown-of-thorns starfish is one of the predators to the reef which feeds on the soft coral polyps.
A coral reef is a fragile ecosystem which requires very specific conditions. The water must be warm (between 69-84 F) and relatively shallow (to depths of 60-100 ft).
Coral reefs exist in shallow waters because they depend on photosynthesis for food production. Photosynthesis is the chemical process by which plants capture sunlight and convert it, along with water and carbon dioxide into energy.

While your child designs their own little slice of sea life you can talk about the various life that lives here, what is being done to preserve it and where its located.

Next, look at how to make this fun hands-on edible coral reef.

How to Make an Edible Reef

Here is a list of some things we used. Your list can vary depending on what you use for plants and animals

One half sheet cake or a boxed cake mix
Vanilla wafers
Assorted candy – airheads, licorice whips, swedish fish, cookies, sprinkles and white chocolate pretzels
Icing in various colors or food coloring for your own icing

Bake your cake according to package directions and allow to cool completely.

Flip pan to carefully remove cake and cut ⅓ of the cake off.

Flip over the two pieces and stack the smaller one on top of the other.

And because reefs have overhangs and caves, you can make some nooks and caves by digging out some of the cake.

Add a little food coloring to the frosting and stir. Use any shade you like to create your base.

Carefully ice all over the cake making different blobs and creating different textures creating the base mound of your coral.

You want it to look like big rocks.

Cut up airheads, licorice ropes and other candies to create colorful coral and push in all over the cake.

Broken white chocolate pretzels make nice coral.

Use the heat from your hands to soften Airheads or other taffy and make some fan coral for your reef.

Also, you could create a makeshift piping bag by putting warm wax into a sandwich bag, cut off a small corner and squeeze to make coral shapes onto wax paper.

Allow to cool and harden then remove carefully from waxed paper.

Finally, add in some fun sea creatures and you can add some fun decorations.

These are from obviously these are not edible.

Be sure to wash them well before using to disinfect them and keep your cake safe.

Super Easy and Fun Aquarium Jar Craft For Summer Activities for Middle Schoolers

July 24, 2022 | Leave a Comment
This post may contain affiliate links. For more information, please see my full disclosure policy.

Your kids will love this fun aquarium jar craft for summer activities for middle schoolers. Whether you’re diving into a study about the oceans or doing a shark unit study, hands-on activities are the way to go. Also, look at my page homeschool middle school for more fun tips.

Either use an upcycled jar or a mason jar from Dollar Tree. This easy aquarium craft for summer activities for middle schoolers is a multisensory approach to learning.

Not all middle schoolers are at the same level of maturity, so a hands-on approach is effective at getting information in.

Super Easy and Fun Aquarium Jar Craft For Summer Activities for Middle Schoolers

In addition, no matter how easy of a project, it can help the information stay in little growing brains.

When we study a particular topic I like to include as many hands-on activities as possible and they range from super simple to more involved.

In addition, with shark week looming I started brainstorming fun and easy ways to learn about sharks and other ocean creatures in a unique way.

Besides, this is easy enough to make for a fun summer activity or to use for a homeschool summer co-op.

Craft For Summer Activities for Middle Schoolers

First, I gathered up some of our favorite books to fit the theme.

Ocean Anatomy,
Basher Ocean, and
The Big Book of Blue for reference.

We really enjoy the illustrations and the way the information is provided in simple little nuggets.

Next, before introducing the mini aquarium jar craft learn a few facts about the ocean.

For example, start with the fact that the ocean is a vast and mostly unexplored part of our Earth.

And it is filled with many beautiful and at the same time frightening creatures.

Encourage your child to be a marine biologist if just for the day.

Learn about a couple of creatures, their habits, feeding, characteristics, and what part they play in the oceans ecosystem.

Ocean Craft for Tweens

Have your middle schooler go through your ocean themed books. And the pile of plastic ocean animals. Choose just two to learn about. Here are the easy stipulations.

First, the animal had to fit in the small plastic mason jar from the Dollar Tree.

Second, the animal has to be one that your child is interested in learning about . This way he can research and learn about the animal for the rest of the assignment.

Although you may school year round, you can use assignments like this in summer to keep writing to a a minimal while sneaking in some learning through summer crafts.

Next, look at this easy list of supplies.

A smooth upcycled jar or plastic mason jar from Dollar Tree
Gravel or sand
Plastic ocean animals
A Hot glue gun
Distilled water
Essential oil or hand sanitizer

How to Make a Simple Jar Aquarium Ocean Craft

Begin by using a smooth upcycled jar or mason jar from Dollar Tree.

Sometimes the empty name brand jars have a good amount of writing and raised designs.

However, jars like spaghetti and pickle jars are good choices. Once you soak the label off they are usually smooth.

I pick up a couple of these plastic mason jars from Dollar Tree every so often because they are great for not only storage but also crafts.

Start by putting hot glue on the bottom of a piece of coral or plastic aquarium plant.

Press into the bottom of the jar.

And if you don’t have one in your plastic animals you can easily make some with craft foam.

They will stand upright and hold up to being soaked in water.

Next, add a layer of gravel or sand, just a bit to cover the bottom.

Next hot glue some of the animals in place.

We didn’t want our animals floating upside down or all piled up on the bottom.

And the glue shows very little through the jar.

We chose a giant squid and whale shark

Add just a tiny bit of hot glue and press them into place.

Once glue is cooled and hardened slowly add distilled water to ⅛” from the top of the jar.

You can add a bit of blue food coloring if you like too.

But previously we found that it made it too cloudy to see well.

Additionally to keep the water from going bad you can add a couple drops of antibacterial essential oil . Hand sanitizer works as well.

Add a bit of hot glue to the threads on the lid, Then, screw into place to keep it from leaking.

Finally, you can add quite a bit to this activity by watching a documentary.

Watch a document while your child puts the jar aquarium together

Too, create the mini aquarium during read aloud time with an ocean themed book keeps wiggly learners interest.

A few more ideas to make this fun are to use chalk pastels. Sketch your chosen animals for a fresh art piece.

Chalk pastels are more intriguing than everyday crayons. Also, have your child create a large model of their animal with paper mache.

Fun Making Ocean Layers Soap | Summer Activities for Middle Schoolers

July 13, 2022 | Leave a Comment
This post may contain affiliate links. For more information, please see my full disclosure policy.

If you’re diving into a study on the ocean layers, doing summer activities for middle schoolers, or want to do an Ocean Unit Study and Ocean Lapbook, our kids will love this ocean layers soap. Also, look at my page Homeschool Middle School for more fun tips.

Besides, there is no better way to learn than with a fun hands-on activity that demonstrates an idea you are trying to get across.

And yes, you could even make this fun soap activity for Shark Week.

Fun Making Ocean Layers Soap | Summer Activities for Middle Schoolers

The ocean is a huge and mostly unexplored part of our earth. As a matter of fact only about 20% of it has been explored and mapped by humans.

It is made up of 5 layers and each is different not just in depth but in temperature.

Too, the life that lives in each layer is very different.

It is fascinating, mysterious, scary, beautiful, and changing.

Today, we are going to create a beautiful bar of soap to demonstrate the 5 layers of the ocean and we can learn quite a bit while completing this activity.

Also, you’ll want to grab a couple of books to reference throughout.

And one of our favorites is Ocean Anatomy because of its beautiful illustrations and concise bites of information, even a high schooler enjoys it!

Another great one, especially for littles is The Big Book of Blue, another one with great illustrations.

Also, Basher has a great line that cover a lot of science as well as other topics.

We used Oceans as a reference during our soap making as well.

In addition, I’ll be sharing some research questions for each layer to challenge your child.

This will encourage them to use a reference book or internet, whichever you prefer to find out the answer.

We are going to make just enough today to make a couple of bars but you could easily double or triple the recipe for a larger batch.

Too, if you have access to a microwave this project would make a great activity for your co-op as well.

Layers of the Ocean

1. The Trenches (Hadalpelagic Zone)

First, The Trenches (Hadalpelagic Zone) is the deepest and darkest layer of the ocean.

It ranges from about 20,000 feet down to an estimate of 36,000 feet. It is freezing and the pressure is enormous there.

Hadal is named after Hades, Greek God of the underworld. While not a lot, there are some creatures that make their home there.

And a question: What is the deepest trench in the ocean? ( The Mariana Trench)

2. The Abyss(Abyssopelagic Zone)

Second, The Abyss(Abyssopelagic Zone) has crushing pressure and extremely cold temps.

And this part of the ocean ranges from about 13,700 feet down to 19,700 feet.

Ocean life is still scarce here but not nonexistent. This layer makes up about 83% of the total ocean.

And a question for your children: Name 3 creatures that live in this zone.
Chemosynthetic bacteria, tubeworms, and small fish, sharks, invertebrates and some crustaceans.

3. The Midnight Zone (Bathypelagic Zone)

Third is The Midnight Zone (Bathypelagic Zone).

The only light you will find in this mid layer of the ocean is from bioluminescent fish.

The Midnight zone ranges from 3,280 feet to 13,135 feet down into the depths.

And a question for your children: What is bioluminescence?
It is the production and emission of light from living organisms.

4. The Twilight Zone (Mesopelagic Zone)

Fourth is The Twilight Zone (Mesopelagic Zone).

Below 660 all the way down to 3,280 feet deep this layer is where some whales travel to eat.

Some of the animals here are darker and thinner for camouflage.

Too, squid and octopus are lurking at these depths.

Question: How many species of animals live in the Twilight Zone?
There are over 700.

5. The Sunlight Zone.

Fifth is The Sunlight Zone.

This top layer of the ocean only extends down to 660 feet.

There is plenty of sunlight here, hence the name, and there is a wider range of temperatures within this zone.

Fun question: In this zone where divers explore, what does SCUBA stand for?
Self-contained Underwater Breathing Apparatus.

Layers of the Ocean Soap Craft

Next, have fun making this layers of ocean soap craft.

Here is your list.

Clear melt and pour soap base
Blue Mica Powder or Soap Colorant
Soap Mold
Your favorite essential oil scents or soap fragrance. (Grab the Caribbean Set with scents like Pina Colada and Ocean Breeze)
glass bowl or measuring cup
5 Small glass bowls for dividing up colors
rubbing alcohol in a spray bottle

First, cut your soap into 1” chunks and place in the glass bowl.

Heat in the microwave for 1 minute and then in 30 second intervals until completely melted.

Mix in your scents to the desired scent strength.

We are going with coconut and lime today for our ocean scented soap, but you can put in any scent or combination you like.

Next, divide soap evenly between your bowls.

We love these little glass dishes from Dollar Tree because they work well for everything from sauces to experiments and at only 4/$1.25 they are a great kitchen or science addition!

Work quickly and add some color to each bowl.

Add only a small amount to the first bowl and adding more as go. We added a tiny bit of green and some black to the last to help make it even darker.

Pour your lightest layer in the mold and spritz it with rubbing alcohol in a spray bottle. This helps remove bubbles and will also help each layer stick together.

Let it set for 15-20 minutes to harden.

You will need to melt each layer in the microwave again for about a minute as it will harden while waiting.

However, no fret because it’s very easy to bring it back to a liquid state.

While we waited for each layer to melt we talked about that particular part of the ocean, looking up facts, watching videos, and reading our books.

Continue adding layers, lightest to darkest, spraying with alcohol between each.

Let your soap sit overnight then remove it from the mold.

Have you ever wondered about the effects of ocean pollution and other waterways? Look at my page ocean unit study and ocean lapbook.

Beware of Ocean Pollution

It’s important that we bring it to our children’s attention now so they can make responsible choices and be part of the clean up solution!

The best way to do this of course is through a fun hands-on activity that lets them see first hand how easily water is polluted, how difficult it is to clean it up and to make it like it was before.

CLICK HERE to go there! #oceanpollution #handsonscienceforkids #homeschoolscience #oceanpollutionactivity

This project can be done with things around the house; you may just need to grab a couple items from Dollar Tree or somewhere else.

First, gather all your materials before you bring in the kids. Kids lose interest quickly if they spend a long time waiting at the table for you to find everything.

Better yet if you have an older kid who knows everything right now (wink) get him or her to do the gathering of supplies.

Next, here is the list of supplies for the hands-on ocean pollution science activity.

A large shallow container
Blue food coloring (optional)
sea shells
clean sand (optional)

water
plastic sea creatures
feathers

Teaching Kids About Ocean Pollution

Then, here is the list for the pollution items and the list for cleaning items.

cooking oil
food crumbs
pieces of plastic bag

dish soap
toothbrush
sponge
cotton balls
paper towels
coffee filters
cotton swabs
tongs
small nets

coffee grounds
straws
soil

Water Pollution Exploration

Start by adding items to your container that belong, explaining to your child that these are the items that naturally occur in an ocean and are part of its ecosystem.

Fill your container with several inches of water.

If you like add a few drops of blue food coloring to your water and mix in.

Place sea creatures, seashells, and sand if you are using them.

Next, talk about what happens when we visit the beach or travel on the water.

As you talk about oil the spills from ships, trash that is tossed aside instead of being safely placed in trash containers let your child add each of the pollution items you have provided.

Stir it all up together. What has happened?

The once nearly clear and pristine water is now discolored.
Creatures are covered in oil and dirt.
The water no longer looks appealing at all to play in does it?
Turtles, dolphins, sharks, and other animals get plastic wrap around them.
Sea animals choke on items that don’t belong in the ocean and die or are suffering from the effects.

What can we do to clean up the ocean?

Ocean Pollution Clean Up Activity

You can pick up bigger items if they are floating on top with a net or tongs, but what about items that sink to the bottom of our deep oceans?

Demonstrate how to use cotton balls to absorb some of the oil on the surface of the water.

Toss in a few feathers to demonstrate what happens to water birds when they pick up oil and other undesirable things from polluted water.

Use Dawn dish soap, a toothbrush, and other items to try and remove the oil and debris from the feathers.

Dawn has a program for cleaning up animals that have been injured due to oil spills. You can read a bit more about it here at Dawn Helping Saving Wildlife for Over 40 Years.

Be Ocean Explorers

Examine clean ocean water, polluted ocean water, and “cleaned” up water.

Grab 3 clear glasses and place water and food coloring in one.

Take some of your polluted water and place in the second.

Finally, after you have cleaned up your water some, put a coffee filter over the third glass and run your cleaned up polluted water over the coffee filter.

Compare the difference in water color and quality.

Even the water that has been cleaned up is still not left unchanged, it is cloudy, dark, and still contains trace amounts of debris.

This makes a big impact on my kids as it allowed them to understand how big an impact peoples actions can have on our water sources.

Look at some pollution vocabulary and spelling words to use for an ocean or water unit study.

Pathogens
Waste water
Pollution
Biodegradable
Hazardous

Pollutant
Habitat
Conservation
Ecosystem

If you are looking for read aloud or independent reading books for your child that go along with the theme you need not look any further than your bookcase or library and grab something anything that has an ocean theme like Island of the Blue Dolphins, 20,000 Leagues under the Sea, Treasure Island, or Swiss Family Robinson!

Continue with your study using some great books to look through or use as living text books.

Earth Science Activity for Kids

This hands-on activity can easily lead into learning about all the fascinating creatures who live in the sea.

Lastly, teaching kids to learn how to care for our earth by not polluting the oceans empowers kids to be part of the solution and no the problem.

You’ll love these other resources to keep expanding how to care for the ocean and enjoy the beauty it provides:
