WIND CYCLE


The Wind Cycle


"

Ecclesiastes 1:6

Viewing the 1769 King James Version. Click to switch to 1611 King James Version of Ecclesiastes 1:6

The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits.


To start class we discussed what we use a fan for (to move air) and how it works (electricity spins a motor that has shaped blades attached to it, the blades pull the air through and we feel the air). We then talked about wind being moving air as well (but it does not need electricity). This led us to a discussion on how wind is formed:
1. Sun heats the air. 
2. Hot air rises. 
3. Cool air moves into fill the space. 
4. This moving air is wind.
On our worksheet we labelled a diagram showing the wind cycle and wrote a paragraph explaining it.
