Density

What is the equation for density?

density = mass / volume

What is this symbol?

Density

What are the units for density?

kg / m cubed

How do you work out the volume of a sphere?

4/3 x pie x r cubed

Core practical : regular shaped solid (ball bearings)

calculate mass
calculate diameter using vernier caliper
use that to calculate volume using equation of a sphere
do mass / volume to work out density

Core practical : irregular shaped solid (rocks)

calculate mass
fill a eureka can with water just below spout
add water and measure displaced water from can
that answer is volume of rock
do mass / volume to work out density

Core practical : liquid (water)

measure mass of empty cylinder
measure volume of water in cylinder
do mass / volume to work out density
