Read It! Station DirectionsEach member of the group will read the passage and answer the questions from the task cards on the lab sheet in the Read It! section.
It is important to remember that the answers will come directly from the reading passage.
Energy TransformationsWind turbines are like airplanes running on the spot—spinning round but going nowhere. They're serving a very useful purpose, however.There's energy locked in wind and these giant propellers can capture some of it and turn it instantly into electricity. Have you ever stopped to wonder how wind turbines work? Let's take a closer look!
A turbine is a machine that spins around in a moving fluid (liquid or gas) and catches some of the energy passing by. All sorts of machines use turbines, from jet engines to hydroelectric power plants and from diesel railroad locomotives to windmills. Even a child's toy windmill is a simple form of turbine.
The huge rotor blades (propellers) on the front of a wind turbine are the "turbine" part. As wind passes by, the kinetic energy (energy of movement) it contains makes the blades spin around (usually quite slowly). The blades have a special curved shape so they capture as much energy from the wind as possible.
Although we talk about "wind turbines," the turbine is only one of the three main parts inside these giant machines. The second part is a gearbox whose gears convert the slow speed of the spinning blades into higher-speed rotary motion—turning the drive shaft quickly enough to power the electricity generator.The generator is the third main part of a turbine and it's exactly like an enormous, scaled-up version of the dynamo on abicycle. When you ride abicycle, the dynamo touching the back wheel spins around and generates enoughelectricity to make a lamp light up. The same thing happens in a wind turbine, only the "dynamo" generator is driven by the turbine's rotor blades instead of by a bicycle wheel, and the "lamp" is a light in someone'shome dozens of miles away.
Which of the following would be classified as a turbine?
A. A lever that allows a switch to be turned on
B. A battery pack used to store energy
C. A water wheel used to convert moving water into electrical energy
D. A spinning top on a table©KeslerScience.com

Explore It! Station Directions
One member of the group will read the task cards in order. The group will be responsible for completing each of the tasks that are being read.
Each member of the group will then write their conclusions down on the lab sheet in the Explore It! section.

1. Use only the necessary cards in front of you to show how the energy flows in a gas powered car.
2. Write your energy transformation on your lab sheet
The law of conservation of energy states that energy cannot be created or destroyed, only transferred.
There are many types of energy including mechanical (kinetic), radiant (light), thermal (heat), electrical, chemical, nuclear, and

When energy flows from one type to another this is called an energy transformation.
Use the examples on the next card to see if you can create the energy transformations with the
cards (cards will be reused). Write them on your lab sheet.
