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.
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?
