I use the following specific heat lab with my kids.  They have fun and actually get good results with the metals

.SPECIFIC HEAT LAB #
DATE:

HYPOTHESIS:  The specific heat (Cp) of objects can be found by Q = mDtCp

MATERIALS:  unknown hot metal object, calorimeter, thermometer, water, scales

PROCEDURE:  1.  Mass the calorimeter, with its top, on a scale.
2.   Fill the calorimeter about 2/3 full with cold tap water – mass this on
the scale with top on.  Record on chart.
3.   Place the thermometer through the lid of the calorimeter and record the temperature of the water on the chart.
4.   Obtain a heated piece of metal from the front desk.   (Record its temperature on the chart.)  Place the metal inside the calorimeter, cover make sure when the top is added the thermometer does not touch the metal.  Record the H2O temp after 30 seconds.


    Mass of calorimeter   Mass of Calorimeter + H2O   Mass of H2O in KG   Mass of metal   Beginning H2O temp   Metal temp   Final H2O temp   Q gained by H2O   Cp of metal   Name of metal

Q = mCpDT        Cp = Q/ (mDT)
