Understanding Wind Measurement and Direction

This video tutorial guides viewers through an activity to determine wind direction using a homemade wind vane. It begins with an introduction to the activity, followed by detailed instructions on setting up the apparatus using common materials like a beaker, pencil, and paper. The video then explains how to construct the wind vane and observe wind direction. Finally, it concludes with key observations about wind behavior and introduces the concept of an anemometer for measuring wind speed and direction.

What is the first step in setting up the wind direction activity?

• Take a beaker full of soil.

• Take a beaker full of pebbles.

• Take a beaker full of sand.

• Take a beaker full of water.

What should be placed at the top of the pencil in the beaker?

• A rubber band

• A paper clip

• A thumbtack

• An eraser

What shapes are cut from the construction paper to create the arrow?

• Circle and rectangle

• Oval and hexagon

• Pentagon and star

• Triangle and square

Why is it important for the tail of the arrow to be larger than its head?

• To balance the weight

• To make it heavier

• To ensure it points in the direction of the wind

• To make it look more attractive

Where should the wind vane be placed for accurate observation?

• Under a tree

• In an open place

• Near a window

• In a closed room

What is observed about the wind's movement throughout the day?

• It moves in the same direction all day.

• It does not move at all.

• It changes direction throughout the day.

• It only moves at night.

What is the term used for moving air?

• Gust

• Breeze

• Draft

• Wind

What device is used to measure the speed and direction of wind?

• Anemometer

• Hygrometer

• Thermometer

• Barometer
