[Q]: Objective: ho emuch energy does a photon have OPTIONS:
- A photon can contain as much energy as you want. All electrons have exactly 1 unit of electric charge, no more, no less. Energy, by contrast, is proportional to frequency: E=hf, where h is the Planck's constant (6.6x10^-34 Joule-seconds).
- A photon can contain as much energy as you want. All electrons have exactly 10 units of electric charge, no more, no less. Energy, by contrast, is proportional to frequency: E=hf, where h is the Planck's constant (6.6x10^-34 Joule-seconds).

[Q]: Objective: How can you curve a piece of metal? OPTIONS:
- Firmly hold the sheet metal in the mechanical sheet pounder. Press on the foot pedal while you hit the sheet with a hammer to create the curve that you want and to smooth it out once the basic shape has been created.
- Firmly hold the sheet metal in the mechanical sheet pounder. Press on the foot pedal while you move the sheet back and forth to create the curve that you want and to smooth it out once the basic shape has been created.

[Q]: Objective: How do you make a double boiler if you don't have one? OPTIONS:
- Select a large pot and a glass bowl that will fit inside of it. Boil approximately one cup of water in the pot. Once the water boils, increase the heat to high. Place the glass bowl inside of the pot and into the water. This will function as a double boiler.
- Select a large pot and a glass bowl that will fit inside of it. Boil approximately one cup of water in the pot. Once the water boils, reduce the heat to low. Place the glass bowl inside of the pot and into the water. This will function as a double boiler.
