Part A
Cut a 7-inch-diameter circle out of card stock. Draw a spiral on the circle as shown. Next, use the scissors to cut along the lines you drew starting on the outside and ending in the center. Use the hole punch or scissors to make a hole at the middle of the spiral and attach the thread with a knot. Tie the other end of the thread loosely around the center of the stick so you can suspend the spiral in the air. Fill the pot with 2 inches of water. Heat the water until it boils, and then turn off the heat source. Let the pot sit for 4 minutes. Holding the ends of the stick with the spiral attached, position the bottom of the spiral right above the top of the pot so it’s not touching the water. Describe what happens.
Part B
What kind of energy does the hot water have?
Part C
Do the hot steam and air moving upward from the pot have kinetic or potential energy?
Part D
Think about the process of heating water, the heating and upward motion of hot steam and air, and the spiral spinning. For these events, list each form of energy associated with the heat source, the water, the steam and air, and the spiral.
Part E
When would the spiral stop spinning, if ever? Why?
Part F
How could you add more energy to the spinning spiral?
Part G
This event shows the motion of a hot gas being converted to the motion of an object. Can you think of a device or machine that transfers the motion of a hot gas to motion of an object?
