The Density Rod Set consists of two rods. The aluminum rod sinks in warm water and floats in cool. This is because cool water is more dense than warm, and the aluminum rod is made to be between those two densities. The PVC rod does the reverse – floats in warm water and sinks in [...]

Regular and irregular objects will be used. Students will devise a way of finding the volume of each object - calculating the volume of a cube or using water displacement for irregular objects. They will calculate the density of each and compare to standard values.
Required Equipment
Density Blocks, Balance, Graduated Cylinder, Various objects.
