background [prelab assignment (10 points) due at the beginning of lab]
using the below items, design an experiment to determine the density of different solids and liquids
determine the density of objects of similar volume, but different mass
determine the density of object of similar mass, but different volume
determine the density of different coins & liquids
various objects (either a cube or cylinder): some objects won't fit into the graduated cylinder
new & old pennies (1982 "divides" old & new pennies), dimes
water; isopropyl alcohol
graduated cylinder / pipet; balance; ruler
methods / data analysis
Content of the lab report (35 points)
data analysis [20 points]
calculation of density of the various objects; show example calculation & identify item
statistics;compare density of __; table of density of various items
disccussion [15 points]
- based on your density measurements, could you differentiate between the __
- different coins ?
- different liquids ?
justify your response by referring to your data analysis.
- simple rationale / basis / implication that
- the cubes have the same volume, but different mass
- the cylinders have the same / similar mass, but different volume
