How to Make a Handmade Weather Vane for Third Grade Students

The method is as follows:

First prepare a few pieces of cardboard, then start rolling them from one corner to form a paper stick .

Stick with double-sided tape and cut off the top part.

Use the same method to roll the second piece of cardboard.

When finished, take the third piece of cardboard, fold it in half, use a pen to draw the shape to be cut out and cut it.

After cutting, stick it on the white paper stick.

Finally, combine the two paper sticks so that the weather vane is ready.

Explanation of weather vane:

A weather vane is an instrument used to determine wind direction.

A weather vane is an asymmetrically shaped object whose center of gravity is fixed on the vertical axis. When the wind blows, the end that creates greater resistance to the airflow allwill move with the wind, indicating the direction of the wind.

The metal weather vane consists of six parts: weather vane, wind wheel, tail fin, movable mast, main mast and base. The main part is made of high quality stainless steel; the fan blades are made of high-quality engineering plastics with strong corrosion resistance; the movable rod part is made of high-quality stainless steel double sealed bearings, which have high sensitivity, low wind start speed and durability.

The weather vanes are easy to install and transport and are widely used in meteorological and chemical industries, mining areas, agricultural production, oil field exploration, wind power generation and other industries. other industries.

Structural function:

The shape of the weather vane can be divided into four parts: tail, counterweight, point rodage and the axis of rotation.

A weather vane is an asymmetrically shaped object whose center of gravity is fixed on the vertical axis. When the wind blows, the end that creates greater resistance to airflow will rotate with the wind, indicating the direction of the wind.
