Ocean Science Experiments for Preschoolers Hands-on Science activities are fascinating for children and keep learning new things exciting. For younger kids, it’s a fun beginner activity to explore different solids, liquids, and gas. This is a fantastic STEM experiment to begin talking about the science behind our oceans and differences in density. Some liquids float above others (like oil and water), while others sink right through. Ocean Science Experiments for Preschoolers and Kindergartenĭensity jars are an easy and fun way to show kids how different liquids and different objects have different densities. 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. It all depends on the weight of the objects we are using. 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. Sand is heavier than water, water is heavier than oil, and oil is heavier than shaving cream, so that is why the density jar is layered that way. 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. It will not go through the shaving cream, so that means the rain is still stuck in the clouds. If you are using glitter, sprinkle that over the shaving cream to represent rain. 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. The small holes with no shaving cream will make it much easier to drop stuff into the jar. 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. Squeeze a thick layer of shaving cream around the inside edge of the jar to resemble puffy clouds. Next, slowly pour in the oil until about an inch from the top of the jar. I prefer to have the amount of water that’s needed already in a pouring cup for the children to use. The 2nd step is for your child to pour the water into the jar slowly so it fills it about 2/3 full. You only need one drop of food coloring to color the water light blue. Have your child fill the bottom of the jar with sand a couple of inches deep, depending on the jar. Science Activity for Kids – let’s get started It makes everything run smoother if you can have the set up ready before you start. Start by gathering your supplies on a tray for your child. Ocean Activities for Preschoolers and Kindergarten Do they think everything will sink to the sand floor, or will some things float? Let’s see what happens. Let your children guess where each ocean animal will land inside your density jar. Ocean Activities for Preschoolers in Science Spend time talking about what types of things live in the ocean and explaining the different layers in this Science experiment helps the children understand what they are learning. However, I have it displayed in list form towards the bottom of the page. Enjoy!Īffiliate links can be found on this blog at no cost to you.īefore doing this science experiment, we took some time to read together about the ocean, beach and ocean life. What you will need to make your Ocean Life Density Experiment is in this picture below. We love learning and sharing about the beach and filling the year with under the sea activities. Ocean Science for Kids – Easy Ocean Life Experiment Kids LoveĪre you starting an ocean theme preschool unit or looking for fun ocean theme ideas to keep your children excited and learning throughout this summer? You’ve come to the perfect place. Have fun! Ocean Science Activities for Kids This ocean density jar has an ocean floor, ocean water, ocean life, the sky, and fluffy clouds. So gather your preschoolers, kindergarteners, and early elementary children for an easy ocean life experiment they will love. Kids will love learning about density with an exciting hands-on ocean activity. Start teaching your children about the beach and ocean life by setting up this fun summer science activity. It’s summer, so that means it’s the perfect time to enjoy activities on Beach and Ocean Science for kids.
