My son loves our science experiments. He is a high energy, sensory seeking little boy who enjoys highly stimulating activities. Science experiments provide just the right amount of everything for him to become fully engage and interactive with what we are doing together. So far we have done a lot of fun things together including fizzing eyeballs, pumpkin-canos, and indoor tornados and rain clouds!
Liquid Density Exploration Science for Preschool
We have been enjoying one big book lately The Berenstain Bears’ Big Book of Science and Nature by Stan & Jan Berenstain. This book nicely illustrates simple concepts like density and matter so I thought we would experiment by making density towers.
Density Tower Experiment Simple 3 Layer Model
We started with a simple density tower with three layers. These layers were maple syrup, water and cooking oil. We talked a bit about what density meant and which liquids he thought were denser. Sort of a sink and float with liquids! He really liked seeing how everything separated and that oil was the lightest! This was quick and simple with the three layers and perfect for a quick lesson or to get everyone interested in making a bigger density tower!
6 Layer Density Tower
Let’s make it a little bigger and try adding some different liquids!
Materials & Set Up
We used tall vase for this one so it would look more like a tower!I thought it would be fun to drop in some Halloween themed items between the layers to test out a little more sink and float action. For an older child, I would probably measure each liquid into a specific cup for pouring to be as accurate as possible. For attention purposes, Daddy jumped in and helped by estimating amounts and it still worked fine! For this one we used Honey, Maple Syrup, Water, Dish Soap, Oil and Rubbing Alcohol.
Honey goes in first. Followed by Maple Syrup, Dish Soap, Water, Oil and lastly the alcohol!
It was neat to watch the liquids pour in and then begin to separate into their own level in this density tower. Liam would exclaim that one liquid was lighter than the other so I guess he got a good idea of what we were trying to do! He also liked dropping pumpkins, spiders and eyeballs into the density tower as well.
Now it’s your turn!
We would love for you to grab a button and display it! Please follow your hosts in some way that you like too. Share a post or two of your fun, family friendly science activities and pin or share some others that you like. Visit all our great science experiments! Blog hops spread the love. I will pin all your great posts to my Science Experiments Pinterest Board too!
