Bryan Spelhaug Tues Lab 8:00am Experiment XI: Specific Gravity and Buoyant Force Date: 11/16/10 Objective: Law of buoyancy, discovered by Archimedes, which states that any object that is completely or partially submerged in a fluid at rest is acted on by an upward, or buoyant, force. The magnitude of this force is equal to the weight of the fluid displaced by the object. The volume of fluid displaced is equal to the volume of the portion of the object submerged. For this lab, we will investigate this hypothesis in order to find out scientifically, if this theory holds truth. Method: For this experiment, we will be using three different sample objects and finding each individual specific gravity. To do this, we first determined the mass of object labeled A in air. Next, we immersed the object in water and recorded our results. We repeated these steps for the object labeled B. For the final test, we used a block of wood and found its mass. The next step was to find the mass of the block while submerged in a container of water. To do this we had to tie the block of wood to a sinker so the block would be completely immersed in the water.
