HEATING WATER IN A PAPER CUP
A paper cup
A Sterno can
Fill a paper cup with water. Measure the temperature of the water. Light a Sterno can and heat the cup of water over the Sterno. If you have a ring and ring stand, you might want to suspend the paper cup filled with water on the ring.
Predict what will happen. How hot can the water become? Will the cup start on fire? Why or why not?
What do you observe happening? Record your observations. Explain the observations.
As an alternative to this activity, prepare the demonstration and present it to some of your classmates. How do they react to the demonstration? What issues arise?
How do your predictions compare to your observations? Record your ideas in your portfolio.
