A student conducted a laboratory experiment to investigate the effect of temperature (hot vs. cold) on the viscosity of a synthetic lubricant. The viscosity was determined by measuring the exact time (in seconds) taken for a steel ball bearing to drop a distance of 50 cm through the lubricant.
Outline what is meant by objectivity in scientific research and state how it applies to this experiment into lubricant viscosity.
