Table of Contents Wind Power
desert rises, and the cooler, denser air above the Pacific Ocean rushes through the Tehachapi mountain pass to take its place. In a state like Montana, on the other hand, the wind blows more during the winter.”
8. Tell students another place (they may have mentioned) conditions are well suited for wind farm is along the coasts of the United States. However, there are people who oppose putting turbines just offshore, near the coastlines. They do not like the way they obstruct ocean views or are concerned about boat traffic or possible damage to birds and sea life.
9. Take out a piece of paper and write the name of the top five places by state you would put a wind farm if you had a wind farm company. (give students a few minutes to do this and share their answers with their groups.)
10. Pass out Student Sheet 1 Module 9. Ask student to complete the worksheet and see if their wind farm company would be successful.
11. Review the answers with class.
Part II: Finding the “Groove” When Sailing Upwind Classroom - 30 Minutes or Outdoor Classroom with Sailing- 2 hours
1. Reference Learn Sailing Right Intermediate Chapters 3 and 4. Show students images in book or have them use the images in the Reach Student Logbook and Portfolio.
2. “Before we investigate how we generate power from the wind using turbines in more detail, let’s explore the science of upwind sailing and “Finding the Groove.”
3. Explain to students, “As a beginning sailor, getting the boat to move is solved by:” • trimming the sails • steering with the rudder • avoiding the “No-Go Zone”
4. Once you master the beginning learn to sail skills, understanding the basic science that makes a sailboat work will help you become a better sailor and make decisions about rigging, sail trim, weight placement, and steering. What indicators can we look at on our sails and shrouds to see if the pressure created by the wind on our sails is even? (tell tales) How do they work? Any ideas?
5. Explain to Students the Science of Sailing using No-Go, Push, Pull, and sailing in the “Groove.” NO – GO A sailboat can not sail directly into the wind. You can try it, but your sails will only flap (luff) and you will be dead in the water… or even start moving backward. When sailing directly into the wind, there is not a difference in wind pressure between one side of the sail and the other. The sail can not generate “push” or “pull.” No push… no pull… No Go!
