What This Book Teaches Best
• Defines wind as the movement of air across Earth’s surface and describes wind as a breeze or a strong gust.
• Explains the cause of wind: the sun heats Earth unevenly, warm air rises, and cool air moves in to replace it.
• Shows how people have used wind over time, comparing traditional windmills (grinding grain, pumping water) to modern wind turbines.
• Describes how a wind turbine works, including blades spinning a shaft connected to a generator that makes electricity.
• Connects wind energy to sustainability by explaining wind farms, offshore wind farms, and wind energy as a clean, renewable resource.

Learning Goals
• Students will explain what wind is using details from the text.
• Students will describe how the sun’s heating of Earth helps create wind.
• Students will describe how traditional windmills used wind to help people.
• Students will explain how wind turbines change wind’s motion into electricity.
• Students will describe what a wind farm is and why offshore wind farms can capture strong winds.
• Students will explain why wind energy is described as renewable and clean in the text.

Key Vocabulary From the Text
• movement — going from one place to another.
• gust — a short, strong burst of wind.
• turbines — big machines with blades that spin in wind.
• generator — a machine that makes electricity.
• renewable — can be used again and won’t run out.

Discussion Prompts
• Pre-reading question: Where have you seen wind do work, like moving something or making power?
• Comprehension questions: What does the text say creates wind?
• Comprehension questions: How did traditional windmills use wind to help people?
• Comprehension questions: How does a wind turbine turn wind into electricity, according to the text?

Printing Tips

1. Best Printing Method (Recommended)
   “Booklet” Printing (Best if Available)
   If your printer or PDF viewer supports Booklet Printing, use this.
   Settings to use:
   • Print mode: Booklet
   • Paper size: Letter or A4 (either works)
   • Orientation: Landscape
   • Print on both sides: Yes
   • Flip on: Short edge
   • Scaling: Fit to printable area
   • Booklet subset:
   o First test: Front sides only
   o Then: Back sides only
   This will automatically:
   • Pair pages correctly
   • Put the cover on the outside
   • Align everything for folding
   After printing, fold in half and staple along the spine.

2. If “Booklet” Printing Is NOT Available
   You can still print this correctly with manual duplex printing.
   Step-by-step:

3. Open the PDF.

4. Choose Print.

5. Set:
   o Orientation: Landscape
   o Pages per sheet: 1
   o Print on both sides: Yes
   o Flip on: Short edge

6. Print all pages.
   Because each PDF page already contains two facing book pages, the result will still fold cleanly into a book.
