How do I make a windmill? How to make a windmill?

Cut a square piece of paper, fold the four corners in half to form the shape of X, and use a knife or scissors to cut the four corners of the paper from the outside to the inside along the folded line until the corners reach half of the center of the paper. Then fold the 1st, 3rd, 5th, 7th, or 2nd, 4th, 6th, 8th, corners back to the center of the paper, and use the wire to thread the center of the paper, the 1st, 3rd, 5th, 7th, and corners of the paper. The center of the paper and the corners 1, 3, 5, and 7 should be supported by a hollow object.

For example, use a waste ballpoint pen refill to cut into a 1-2 cm long section and place it between the center of the paper and the corner of the paper. Finally, the wire was fixed from the back of the paper to a stick. As soon as the wind blows, it will turn.

Take the part of the line as the boundary, cut it upward, a total of 4 sides, as shown in the figure: then gather each corner up at the same point, as shown in the figure: then fix it with tape or glue, as shown in the figure:

Poke a hole in the middle, not too big, not too small, as shown in the picture: use a black pen refill, put it into the windmill, as shown in the picture: put it in a windy place or next to a fan, and the kite can be turned!

A reed leaf is the leaf of a reed. Reed is a perennial aquatic or wet tall grass, growing next to irrigation ditches, river embankments and swamps, etc., growing all over the world, reed leaves, reed flowers, reed stems, reed roots, asparagus can be used in medicine. Chinese folk customs have the custom of wrapping zongzi with reed leaves during the Dragon Boat Festival.

Reeds grow in ponds, marshes, river banks, and watery areas along river benches, and often form reed ponds. In China, it is widely distributed, among which the Dongting Lake in Hunan[1], the Liaohe Delta, the Songnen Plain and the Sanjiang Plain in the northeast, the Hulun Drain Bear and Xilin Gol Grassland in Inner Mongolia, the Bosten Lake, the Ili River Valley and the Tacheng Emin River Valley in Xinjiang, and the Baiyangdian Reed Area in the North China Plain are the distribution areas where large areas of reeds are concentrated.

The custom of wrapping zongzi with reed leaves has long appeared in China, and the varieties are more colorful with new jujube and walnuts. There are also many children who pick up and make windmills.

The steps for making a windmill are as follows:

Many children like to play with windmills, so how to make fun windmills for children at home when they are at home?

Tools Materials: scissors, colored paper, double-sided tape, rod needles.

01First of all, we will prepare the materials needed to make the windmill.

02 Fold the colored paper diagonally, and then fold the other two corners.

03 Then cut the four diagonal 2 3 or so.

04Fold the four corners towards the center of the paper, noting that the distance between the center needs to be about 1cm.

05 Then fix it with glue.

06Turn the windmill over and glue the double-sided tape in the center.

07Finally, glue the rod needle on it, so that the whole windmill is made.

By making windmills, children's hands-on ability and interest in doing handicrafts can be enhanced. It can also allow young children to learn to look at step diagrams to enhance cognitive ability. When playing with the windmill, children can sense the presence of the wind by observing it, and know that the wind can make the windmill turn.

Let the children know how to dial, run, throw, blow and other ways to make the windmill turn.

Let the children make their own windmills, which improves their hands-on ability; Let the children discover the secret of the windmill rotation in the windmill game, experience the fun of exploration, enrich the children's experience, and develop the children's thinking; Let children perceive the existence of natural phenomena one by one in the game of windmills, know that nature will bring us many interesting and useful things, experience the magical charm of nature, and stimulate their love for nature.

Here's how to make a windmill:

Prepare a square of colored paper, fold it in half along the two corners, open it, take out the scissors, cut about two-thirds along the four creases, and lift the left corner of the triangle.

Stick it to the midpoint with double-sided tape, then take a square cardboard and roll it into a thin stick, and stick the thin rod to the center of the windmill, and a simple and beautiful little windmill is ready.

As a kind of agricultural tool, the wooden windmill has a long history in China, and its basic structure is: there is a trapezoidal feed bin at the top, a funnel below is out of rice, a small funnel on the side is out of fine rice, deflated grains, and the tail is out of chaff;

The wooden garden-shaped "big belly" has an impeller and an iron crank handle, and the wind blades are rotated by hand to blow the grain, and the wind generated by the fast rotation speed is also strong, and vice versa. It is the most delicate and complex traditional agricultural tool in China, which is composed of bellows, rockers, body, grain drain hopper, air outlet and other components.

When the farmer is fanning the crops, he should work closely with both hands, first shake the windmill with his right hand to let the wind fan out, and then put the shelving down a few gears with his left hand to let the grain roll down from the opening of the body floor.

At this point, the wind passes through the spilled grains and carries the grass clippings out of the air outlets. The plump grains are heavier, so they roll vertically down from the mouth of the funnel and fall into the basket attached to the mouth of the funnel.

The specific inventor is no longer verifiable, and it is said that it was invented by Luban. The age of its invention will not be later than the Western Han Dynasty at the latest. The Han Dynasty Historical Tour "Urgent Chapter" has a saying that "the stone is not a fan and a dustpan". The "fan" here is the "fan car".

Here's how to make a windmill:

1. Take a piece of A4 paper. If you have other papers, you can do it. Fold one corner 45°.

2. Fold the extra rectangular paper in the upper part and cut it off with a knife.

3. Then in the middle of the longest side, fold it in half again to form a smaller triangle.

4. Cut the sides of the triangle to form an independent triangle, but leave a distance of 1cm in the middle, do not cut, if you cut it, it will really become a triangle. The middle point is the center of the windmill.

5. Then open the paper. At this point, the paper is cut diagonally, but remember, the middle 1cm are connected to each other.

6. Use a thumbtack, from the bottom midpoint upwards to pierce out. If you don't have a pushpin, you can also use a paper clip to straighten it instead.

7. Start with any triangle and thread a corner through the pushpin.

8. Thread the remaining three triangles onto the pushpins in turn. The windmill is ready! Run against the wind!

Expansion: Windmills are power machines that do not require fuel and use wind as an energy source. Early wind turbines were also known as windmills. Modern wind turbines mostly refer to wind turbines for power generation, and some are also used for water lifting and irrigation.

The ancient windmill was developed from the sails, it had 6 or 8 sets of canopies like sailboats, distributed around a vertical axis, and when the wind blew, it rotated around the axis like a marquee, which was called a marquee-type windmill. Due to its low efficiency, this kind of windmill has been gradually replaced by wooden cloth windmills with horizontal rotating shafts and other windmills, such as "vertical windmills", "automatic rotor windmills" and so on.
