Which of these objects will float and which will sink in water?

DensityObjectives

Know what density is and understand how to calculate

density.

Outcomes(5) Describe what density is.

(6) Calculate density accurately using practical measurements.(7) Evaluate different methods that can be used to calculate

density.

Key terms: density, area, volume, mass.

Density D = m/v (g/cm3)

Mass usually expressed in grams

Volume usually expressed in cm3 or liters, etc.

Density = amount of matter per unit volumeDensity is the ratio of mass to volume

If the volume stays the same and the mass increases . . . the density will increase

If the mass stays the same and the volume increases . . . The density will decreaseKey terms: density, area, volume, mass.
