Students perform an experiment to collect data that that can be used to determine the density of an unknown liquid. they have a tall cylinder containing the liquid and some cubes of different sizes but the same known mass mthat all sink in the liquid. they only have a meterstick and a stopwatch to take measurements (a) describe a procedure the students could use to collect the data needed to create a graph that can be used to determine the density of the budincluding the measurements to be taken and any steps to reduce experimental uncertainty
