Science

Busy week working on our experiments.

We also had Ms Sarah Jackson come down on Friday from Clipper Wind in Cedar Rapids to tell us about the wind turbines.  She shared many interesting facts:

• The tower of a wind turbine is 400 feet tall. (That is taller than the Statue of Liberty)
• The blades are 150 ft. long. (Approximately the length of 1/2 a football field.)
• The blades are made out of fiberglass.
• Wind turbines can generate energy if the wind is only traveling 9 mph.
• The blades on the turbine can move over 100 mph.
• There are 4 generators inside that produce the electricity.
• The generators are approximately the size of a washing machine.
• The turbines are only ran by the wind, they do not have a motor inside to run the blades.
• Wind is a renewable energy source.
• Texas has the most wind turbines, Iowa comes in second.
• Clipper Wind has over 750 wind turbines in the United States and in Mexico.
• The turbines provide power to over 700,000 homes.
