Teach Engineering: Density Rainbow and the Great Viscosity Race
Students explore the densities and viscosities of fluids as they create a colorful 'rainbow' using household liquids. While letting the fluids in the rainbow settle, students conduct 'The Great Viscosity Race,' another short experiment...

Lapeer County Schools Science Resources: Density Lab
A simple lab experiment for students to find the density of two solids and a liquid (does not use water displacement). Note that number 1d should not state "weighs" since mass is being found.

Reach Out Michigan: Are All Liquids the Same
This experiment demonstrates the density of selected liquids.

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.

The Science House: Daffy Densities
In this lab experiment, students will use 4 solids and 6 liquids to create colorful, layered rows demonstrating that less dense materials will float on top of the more dense materials.

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.
