"Wind Direction and Wind Speed" Weather PPT Courseware 2

Get your hands dirty: Make a weather vane

Production Method:

1. Choose a harder straw and cut a gap of about 1 cm lengthwise at both ends of the straw.

2. Use cardboard to cut an arrow of moderate size and a slightly larger wing. Insert the gaps at both ends of the straw and secure.

3. Use a pin to pass through the balance point of the straw and insert it into the elephantiasis of a section of the pencil so that it can rotate freely.

Note: The arrowhead and arrowhead, as well as the inserted pin, should be in the same plane as possible.

The arrow on the weathervane points in the direction the wind is blowing.

Now ask the students to take out the orientation map sent to you by the teacher and insert the pencil lead into the center point of the orientation map. Blow into the weathervane from different angles and measure the direction of the wind you are blowing.

When using a homemade wind vane to measure wind direction, please note:

First, use a compass to determine direction.

Second, wind direction observation activities must be conducted outdoors in an open area.
