The apparent weight indicated by the scale will be smaller because there is still a small buoyant force pushing up on the metal cylinder.

This is expected because metals are typically more dense than water and therefore, are obviously not able to float. The calculated densities are significantly larger than water (1 g/cm3).The possible sources for error in the this experiment include, inaccurate senor readings, remaining water residue on the metal cylinders, an added volume of displaced water due to the hook on the cylinders, currents in the water that push the cylinders, and cylinders swing on hooks after they are in place.(between actual density and calculated density) Data was recorded after each measurement.Steps Two & Three were repeated four times with different metal cylinders.The metal cylinders were placed in the water and then measured.The group then began recording data by measuring each metal with its actual weight, pressing tare before every measurement and drying the metal to prevent added weight from the water that was collected.The group partners set up both the DataStudio experiment and connected the computer to the PASCO interface.In this lab, the group used this principle to find the density of various metal cylinders. Archimedes’ principle, named after Archimedes of Syracuse, describes that the weight of fluid that an object displaces is equal to the buoyant force. This commonly known force is because of the greater pressure of fluid beneath an object that pushes it in an upward direction. Buoyancy is an upward force in fluids that counteracts gravity and gives objects the ability to float. Did you know that the force of buoyancy in water reduces an average persons body weight by nearly 90 percent? Consequently, this buoyant force also relieves stress on joints and muscles for rehabilitating patients.
