The third laboratory work in the 8th-grade physics curriculum (specifically the widely used program) is titled "Measuring the Specific Heat Capacity of a Substance" ( 1.2.1 ). Another common variation for this grade level is "Determining Relative Air Humidity" ( 1.2.2 ).

with a standard table of specific heat capacities to identify the metal (e.g., iron, brass, or aluminum). Note that small deviations are normal due to heat loss to the calorimeter walls and the air during transfer ( 1.4.2 ). The third laboratory work in the 8th-grade physics
