Under the Sea Preschool Activities

Before doing this science experiment, we took some time to read together about the ocean, beach and ocean life. Spending some time talking about what types of things live in the ocean and explaining the different layers that will be in this Science experiment helps the children understand what they are learning.

Ocean Activities for Preschoolers in Science

Let your children guess where each ocean animal will land inside your density jar. Do they think everything will sink to the sand floor or will some things float? Let’s see what happens.

Start by gathering your supplies on a tray for your child. It makes everything run smoother if you can have the set up ready to go before you start.

 

Science Activity for Kids – let’s get started

Have your child fill the bottom of the jar with sand, a couple of inches deep depending on the jar.

You only need one drop of food coloring to color the water light blue. The 2nd step is for your child to pour the water into the jar slowly, so it fills it about 2/3 full. I prefer to have the amount of water that’s needed already in a pouring cup for the children to use.

Next, slowly pour in the oil until about an inch from the top of the jar.

Squeeze a thick layer of shaving cream around the inside edge of the jar to resemble puffy clouds. Squeeze a very thin layer on the top of the oil in the center of the jar opening, leaving one or two little holes with no shaving cream. The small holes with no shaving cream will make it much easier to drop stuff into the jar.

I prefer to do the shaving cream squirting myself, so it doesn’t go all over the place, but if you have older children doing the science activity I am sure they can make the clouds themselves.

If you are using glitter, sprinkle that over the shaving cream to represent rain. It will not go through the shaving cream, so that means the rain is still stuck in the clouds.

Now it is time to start the density experiment: The sand represents the ocean floor, the water is the ocean water, the oil is the sky, and the white shaving cream is the clouds.

Sand is heavier than water and water is heavier than oil and oil is heavier than shaving cream, so that is why the density jar is layered that way.

Start dropping in ocean objects to see which will go down in the sand, which will float in water, and which will float in the oil. It all depends on the weight of the objects we are using. We had some ocean objects on the sand, some floated in the water for a few minutes, and the whale, starfish, and the sea plant floated in the oil.

Density jars are an easy and fun way to show kids how different liquids and different objects have different densities. Some liquids will float above others (like oil and water) while others will sink right through.
