Prathom Five Science students have just finished a very interesting Mass, Volume, and Density Lab experiment in the EIP Science Lab. Students used objects of their choosing, then proceeded to find the mass, volume, and density of those objects.
Mass was found by using a set of scales to weigh the objects (tennis balls, golf balls, ping-pong balls, watches, wallets, etc.) by balancing the scales with a set of laboratory weights.
Volume was found by using Archimedes’ principle. Objects were fully submerged in water. Water that spilled out of the container was collected and measured. That was the volume of the object.
Density was found by dividing an object’s mass by its volume. (Mass/Volume=Density).
Archimedes’ principle indicates that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces.
