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?

10 Popping Popcorn Facts

January 19th is National Popcorn Day.
It’s over 5000 years old.
The first commercial popcorn machine was invented in 1885 by Charles Cretors.
Convenient microwaveable popcorn was invented by the Pillsbury company in 1982.
The unpopped kernels at the bottom of a bag are called old maids.
Kernels are made up of about 4% water and that water causes it to pop when it’s heated up.
Nebraska produces the most popcorn in America at about 250 million pounds per year.
Way back in the 1800’s, it was often eaten as a cereal with milk and sugar.
The scientific name is Zea Mays Everta.
It was not allowed in movie theaters in the early 1900’s.

Also, you’ll love some history facts.

Besides being a delicious snack, your child will appreciate a bit of corn and popped corn history.

History of Corn and Popcorn

It was introduced to early American settlers by the Indians.

The first corn farmers were the American Indians, the Aztecs, the Incas, the Mayas and others.

Additionally, there are varieties like black corn, pink corn, red corn and white corn, besides the better-known yellow corn.

Writing of Peruvian Indians in 1650, the Spaniard Cobo says, “They toast a certain kind of corn until it bursts. They call it pisancalla, and they use it as a confection.”

Pre-Inca Peruvians worshipped a corn goddess adorned with a crown of corn ears radiating from her head like the spokes of a wheel.

How does corn grow? The kernel is the seed. The seed is planted in the soil. The stalk begins to grow. The stalk is the stem. Leaves grow from the nodes.

Ears of corn grow from the nodes. Each plant is male and female. The silk catches pollen from the tassels.

Then pollen travels down the silk and fertilizes the kernels.

Next, here are some book ideas.

Finally, here is a fun and simple experiment.

You can easily add on to this experiment by adding more brands, different varieties, or by trying to pop them via different methods.

Track the results. For example, by microwave, pan pop and air pop.

Or by using this method I am showing you that is the easiest for all age groups- microwaved in a paper bag.

Popcorn Science Experiment

Before you begin you want to stress to your child that in a scientific experiment

You want to keep all variables the same except for one thing which is the brand.

It is very important that you use the same method to pop all 3 types of popcorn and that you use the exact same amount for each one.

You will need:

3 different brands of popcorn
3 paper bags
Smalls bowls
Pen

Directions:

Start by having your child make a hypothesis (an educated guess) on which brand they think will pop the most and the least.

Label each of your paper bags with the brand of corn you are using.

Then, have your child count out 100 of each type of popcorn into little bowls, make labels to keep track as you transfer popcorn.

Transfer each bowl to the correct paper bag and roll it down tightly.

Heat in the microwave for 3 minutes.

Repeat for each bag.

Remove bags and have your child either count the number of unpopped kernels left or the number of popped for each and write it down on your label.

Talk about the results, was their hypothesis correct? Were they surprised by any of the outcomes?
