Purpose: To learn how scientists use indirect measurements to gain knowledge about physical properties. Specifically, to use Archimedes Principle of buoyant force to determine the density of a solid. Theory: Many times, scientists need to measure things that defy attempts at direct measurements. Many measurements, such as the temperature of the sun, have been derived quite accurately in this way. One of the first recorded uses of indirect measurement was that of Archimedes to determine the density of an alleged gold crown. Legend has it that the king demandd that Archimedes determine whether the crown was gold and threatened him with execution if he failed to do so. Archimedes came upon the answer while bathing and shouted “Eureka! I have it!” The basis of Archimedes principle was the buoyant force he felt while bathing. He reasoned that when any object is placed in a fluid, such as water, the fluid exerts an upward buoyant force. He further reasoned that the
