Think Like a Scientist for Renewable Resources and EARN A REWARD


Wind Energy is a renewable resource.  In some areas of the country, large wind turbines (similar to windmills) are being constructed and used for generating electrical power.  Obviously you need windy conditions.....  in fact, scientists recommend that wind speeds be greater than or equal to 6.5 m/s (meters per second) in order for wind turbines to work well.

TO EARN A REWARD:

(1) Use this link to download a color map of wind speeds for the United States.  Wind Map for United States (If you have trouble, Mrs D can provide you a map.)

(2) Review the legend at the bottom right of the map which shows different colors for different wind speeds – remember we are looking for wind speeds of 6.5 m/s or greater.

(3) Pick out ten states where you (as a scientist) recommend installing wind turbines for generating electricity.  Mark them clearly on your map.

(4) As a scientist, why do you think these states are “windier” than other states?  Your answer should include at least three reasons (or factors) that make certain states “windier” than others.  Write down your answers on a piece of notebook paper.

Turn in your marked up color map and your paper with the answer to question 4 BY CLASS ON FRIDAY, OCTOBER 7th to receive an award!!
