Inquiry in Action: Comparing the Density of Different Liquids
How do the densities of vegetable oil, water, and corn syrup help them to form layers in a cup? Students will carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are...

Science Fun: Layered Liquids
This experiment allows you to dramatically demonstrate the different densities of five different common household liquids.
Energy4Me
Energy4me: Fracturing With Gelatin
This activity aims to demonstrate how fracturing fluid, under pressure, is able to create a fissure in the rock layer. Students will be able to see the syrup come out at a high velocity to crack the gelatin. The gelatin, however, will...

Science Buddies: Can Water Float on Water?
Of course it can, you say: ice is water and ice floats. And you're right. But we're talking about water in the liquid phase Can liquid water float on water? The goal of this project is to investigate what happens to layers of water with...

Teach Engineering: Density & Miscibility
After students conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson plan to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the...
Woods Hole Oceanographic Institution
Woods Hole Oceanography Institute: Activity: Demo for Density
In this experiment, students look at Deep Hypersaline Anoxic Basins, or DHABs, that are present in the Eastern Mediterranean, and make a model of a DHAB to investigate how liquids that have different densities can form layers. This...
