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

2. Objectives 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.

3. D = m/v (g/cm 3 ) Mass usually expressed in grams Volume usually expressed in cm 3 or liters, etc.  Density = amount of matter per unit volume  Density 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 decrease Key terms: density, area, volume, mass. Outcomes (5) Describe what density is. (6) Calculate density accurately using practical measurements. (7) Evaluate different methods that can be used to calculate density.
