Alka Seltzer, Oil and Water Science Experiment!
Here’s another wonderful Saturday Science preschool science experiment that is easy to set up and fascinating to watch. Lately, we have been focusing on a lot of simple science experiments with water. It has been awhile since we mixed it up with oil! Just a few simple and common ingredients and you are well on your way to ooohhhs and aaahhhs by everyone including adults. Feel free to explain the science as much or as little as you wish depending on the age and attention of your child. Liam is still a little and has a limited attention span. For these reasons, we tend to stick with just making some simple observations and experimenting with the activity as much as he enjoys being a part of it! I would rather spark his curiosity with fewer words then turn him off all together by making him sit and listen to my definitions!
Simple Science Experiment Set Up
Simple Science Observations
Let’s get started!
Fill the jar with oil to about 2/3 full.
Fill the jar with water to almost full.
Add a good amount of food coloring so you can see the differences in density! You could also add sequins or glitter here too. We added some sequins like snowflakes but it wasn’t anything remarkable. Liam did work on getting them to go down with the tablets. Once they got underneath, they would sometimes catch a bubble and ride up!
Add a small piece of the tablet. We broke the tablets up into little pieces so that we would have lots to try to have smaller eruptions! We used two full tablets which is probably the best amount. Of course he wanted more and it lost some of its effect, but he love adding it just as much!
Observe the fun and use the flashlight to light up the bubbles.
Cover and shake if interested and watch the water and oil separate again!
Time for more Saturday Science!
