Density and Buoyancy (Science Experiments)
Relative density can be observed
Density: Can a scale of relative density predict whether one material floats on another?

What does it mean when it is said that one type of is more dense than another? What does densityThe mass of a substance divided by its volume. tell us about the nature and behavior of a substance? How does density affect the tendency of an object to float or sink in a liquid?
The density of matter is determined by the of a given volumeThe amount of space occupied by a three-dimensional object. of that matter. Any object at a given temperature and pressure will have a fixed volume, determined by the quantity of space it occupies and measured in cubic inches (cubic centimeters or milliliters). It also will have a fixed mass, determined by the quantity of matter contained in the substance. Mass is measured in pounds (kilograms). Density equals mass divided by volume.
The mass of different substances can vary greatly. The atoms that make up lead are tightly packed (at room temperature and pressure) and...
