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

purpose

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

materials

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

student design

Content of the lab report (35 points)

data analysis [20 points]

data table

calculation of density of the various objects; show example calculation & identify item

~~statistics;~~compare density of __; table of density of various itemsliquids

coins

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
