Serc: Layering Liquids
A lab activity to show students how different densities of liquid layer on top of each other by using four different colored liquids that contain different levels of salinity. This activity can also be used in an ocean unit where...

Chem Collective: Identifying an Unknown Liquid From Its Density
In this activity, students use the virtual lab to design an experiment to determine the identity of mislabeled bottles using the densities of the solutions inside.

Serc: Exploring the Properties of Liquids, With an Emphasis on Density
Students experiment with liquids; comparing and contrasting, and creating a density tower leading to a beginning understanding of density.
Science and Mathematics Initiative for Learning Enhancement (SMILE)
Smile: Comparing Densities of Different Liquids
This lab experiment has students observe and compare the density of five different liquids while measuring mass and volume.
Science Education Resource Center at Carleton College
Serc: Mn Step: Sink or Float: All Liquids Do Not Have the Same Density
An experiment in density. After a review of floating and sinking of different materials, students test four bottles, all holding four ounces of water, to see if they will float or sink. They each contain a different density of sugar...

Science Is Fun: Dancing Raisins
An experiment in buoyancy which involves making raisins float by using carbonated soda pop. Students then try the same test with other materials. Instructions for making one's own carbonated liquid are also provided.
