Liquid Density Science Experiment

We cannot get enough simple science over here. This Liquid Density Experiment was perfect for us. I could not wait to try it out with my preschooler one afternoon. I had so much fun working on this experiment with him. We got to spend time together and learn all at the same time. This was a wonderful afternoon project for me and him.

Liquid Density Science Experiment

What we used:

oil

bleach

food coloring

measuring cups

glass jar

corn syrup

What we did:

We added red food coloring to our 1/2 cup corn syrup.

Then we poured it into the jar. We used a recycled spaghetti sauce jar. Psss, I have a confession. I have a box full of jars like this for moments just like this, ha. So glad I had them already saved so we could work on this project.

You can use any glass jar. A mason jar…

Then we added the 1/2 Cup oil.

This process is to introduce density to kids. Showing them that the denser liquid sinks to the bottom and the less dense one floats or sits on top of the denser one.

Then we mixed blue food coloring into a 1/4 cup of water. And added to the glass jar.

Wow, can you tell what just happened as we added the blue water? The water sunk below the oil.

I think the colors are just so cool looking in this jar. After we poured the water in we let it sit a few minutes to settle.

Then we took a 1/2 to 1 cup of bleach and poured it into the jar. Now to wait to see what happens.

We waited and waited. This part seemed to take several minutes so do not give up. After several minutes of waiting, we could see the blue water turning white.

We now see that the water and bleach have the same density. I enjoyed this experiment just as much as my preschooler. I really enjoyed seeing his face and hearing his questions as we went through each step.

Once we had finished our liquid density experiment we left the jar to show little brother when he woke up. This is not only a cool experiment, but it leaves you with a fascinating sensory bottle. Since I was worried about little brother and the glass jar, I poured this into a clear plastic bottle before he woke up. This way he got to explore the bottle on his own.

We hope you and the kids can enjoy this one as much as we did. What are some of your favorite simple science experiments to do with the kids? We would love to hear from you. We love finding new experiments to try out over here at my house.

This looks great- just the kind of activity the preschooler and I like to do 🙂 My only questions is… what is corn syrup? I’m in the UK and we don’t (as far as I know) have it over here??

You can use golden syrup for light corn syrup (like above) and treacle for dark corn syrup. (Thank you, Google! lol!)
