Define turbine and generator.

Definition should include

• turbine—a rotary engine actuated by the reaction and/or impulse of a current of fluid (such as water, steam, or air) subject to pressure; usually made with a series of curved vanes on a central rotating spindle
• generator—a machine by which mechanical energy is changed into electrical energy.

Process/Skill Questions:

• When was the first turbine developed? What was it?
• Why might turbines and generators be required to create electricity?
• What other components are used with a turbine and a generator?
