PEEPs are amazing little marshmallow candies that have so many uses beyond just being a sweet! Use these ideas to bring your PEEPS into the classroom with these PEEPS STEM activities for kids. Today, try the PEEPS density science experiment!
PEEPs Density Science Experiment
This is a fun activity that combines fun with science. It’s a win-win.

- Liquids with varying densities (we used water, Vegetable Oil, honey, Corn Syrup)
- PEEPs candies
- Clear jar (we used a mason jar)
All science experiments start with a question. In this case, we knew from last year that PEEPs will float in water, but Monkey wanted to know if there was any liquid that was denser than a PEEP and could keep it down. We hypothesized that the corn syrup and honey would be thick enough to keep the PEEP down.
The PEEPs Density Science Experiment
Start by layering your liquids. We knew that honey was the heaviest of our liquids, so we added it first and added the other liquids in order of their densities. We layered honey, corn syrup, water, and oil in our jar.
Take a fork and slowly push your PEEP down into the bottom of your container. Let go. What happens?
Watch the video to see what happened in our case:
Take it a Step Further
If you want to go a little deeper, see if you can manipulate the PEEPs so that there is enough air removed from the PEEP to stay under the liquid. From what we read, squishing the PEEP into a ball or freezing it will make it denser and less likely to rise to the top of the jar. See what layer it stays at when you change the density of the PEEP!
