Generally speaking the materials which conduct electricity the best also conduct heat very well. So metals like silver and copper will conduct heat well, while materials like glass and rubber will not.
A materials ability to conduct heat is described by its Thermal Conductivity, k, the higher the conductivity, the better it conducts heat. You can look up values of the thermal conductivity for common materials in many general high school or college level physics and chemistry books.
Other than that, youre on your own. Try experimenting, thats the point of a science fair project.
