The student will investigate the relationship between the mass flow rate of salt passing through a funnel and the mass of salt in the funnel. Salt will be poured through a funnel into a beaker and the time taken for all salt to leave the funnel will be measured using a stopwatch. The mass of salt and flow time will be recorded over six trials. The mass flow rate will be calculated and plotted against mass to determine if the relationship is proportional, inversely proportional, or independent. Limitations and improvements to the experiment are discussed.
