Here are a couple of interactive websites on heat transfer:
See if you can make the heat in the beakers equal in 5 minutes, using one of the materials (glass, aluminum, copper, or steel). Which one works the fastest? What does this mean?

Try this experiment, to heat up the water, using different metals:
