Mass
Matter is anything that has Mass and takes up space (has Volume).
Mass a measure of the amount of stuff (matter) in an object. Measured using a Triple Beam Balance. Volume a measure of the amount of space an object occupies. We use the water displacement method to measure the volume of an irregular shaped object.

Typical Density Questions
What
are the formula and units for Density?
D= M/V units are g/cm3 or g/ml What is the equation for calculating the volume of a regularly shaped object? Length X Width X Height What is the best way to calculate the volume of an irregularly shaped object? Using the water displacement method How do we calculate the mass of an object? What units do we use for mass? We calculate the mass of an object by weighing it on a balance we use grams for the units of mass 
What would the volume of a cube be with a side that was 10 cm long?
10 x 10 x 10 = 1000cm3 What would the density of the cube above be if the mass was 700 grams? 700g / 1000cm3 = .7 g/cm3 Would the above cube float or sink in water? Explain why. The above object would float in water because it has a density less than 1.0g/ml which is the density of water. In the equation D = M/V what do the letters D, M, and V stand for? D = Density M= Mass V= Volume Calculate the density for an object that has a mass of 96 grams and a volume of 24 cm3. 96 / 24 = g/cm3
