The more specific the method of making small inventions for elementary school students, the better

Fast!!! soaked. Hurry up and play the second stage.

Suitable for first-year students to make small inventions: mini wind chimes or harps.

Here's how to make it:

Wrap the used glass bottle of oral liquid (the quantity can be selected by yourself) and wrap the glass bottle with colored paper to make it more beautiful;

2.Fill the bottle with different amounts of water so that it will make a different sound when tapping;

3.Using a rope or wire (you can wrap the wire) to make a wind chime or harp as you like, the glass bottle is combined.

About the invention:

1) Generally speaking, invention is the process and result of applying the laws of nature to solve unique problems in the field of technology and proposing innovative solutions and measures. Products were invented to meet the needs of people's daily lives. The results of the invention either provide an unprecedented model of artificial natural objects, or provide new processes and methods of processing and production.

Machinery and equipment, instrumentation and equipment, and various consumer goods, as well as the innovation and transformation of manufacturing processes, production processes, and testing and control methods, are all inventions.

2) In the field of intellectual property, invention refers to one of the types of patents for inventions and creations protected by the Patent Law, and refers to new technical solutions proposed for products, processes or their improvements. Inventions in the field of patents have their own defined objects of protection, or subject matter of protection.

3) Word interpretation. 1) Creation (new things or methods);

2) play creatively;

3) Discovering a combination of one or several natural elements or substances that others have not discovered.

4) Inventions in Ancient Chinese: Enlightenment and Clarification.

5) One of the types of inventions protected by the Patent Law refers to new technical solutions proposed for products, processes or improvements thereto.

Small inventions for primary school students: simple and practical, low-cost production.

Gizmos:

1. Homemade badminton.

Prepare materials: 1 empty drink bottle, 2 foam fruit net covers, 1 rubber band, 1 glass marble.

Production process:1Take a 250ml empty beverage bottle and cut off the top half of the bottle;

2.Divide the cut part into 8 equal parts, cut it to the neck of the neck with scissors, and then cut each part into the shape of petals of the same size;

3.Put the foam fruit net sleeve on the outside of the bottle and fix it at the mouth of the bottle with a rubber band;

4.Wrap another foamed fruit net around a glass marble, stuff it into the mouth of the bottle, plug it tightly and expose about 1 cm;

5.Cut off half of the ping pong ball, cover the bottom of the hemisphere on the mouth of the bottle, cut the four sides into a whisker, cover the mouth of the bottle and fix it with a rubber band.

6.After beautification and retouching, a homemade shuttlecock was completed. Hit a dozen with a badminton racket and see how it goes?

2. Homemade soap paper.

Materials and tools: white paper with good moisture absorption, small pieces of soap, a brush and disposable beverage cans.

Method: Chop the soap first and put it in a jar, put the cup on the stove after filling it with an appropriate amount of water, wait for the soap to melt, cut the white paper into the size of a matchbox, apply the soap liquid one by one, and then take it out to dry it to become soap paper.

3. Homemade hot air balloons.

1.First of all, we cut 6 to 8 leaf-shaped pieces of paper out of soft paper.

2.Fold them in half and glue their edges together to make a balloon.

3.Tape the four wires to the bottom of the balloon. Attach the other end of the thread to the table with plasticine.

4.Try to turn the speed of the hair dryer as slowly as possible. Aim the blower up at the bottom opening and turn the switch on. The balloon will slowly grow larger, tighten the string, and leave the table.

Fourth, homemade flashlight.

The specific method of making it is to remove one end of the lid of a waste can (such as a Lulu beverage can) and knock the other end with a round hammer. Roll up two No. 1 batteries with thick corrugated cardboard and put them into the tank with the positive electrode facing up and the negative electrode facing down.

Find a suitable plastic lid (such as a magic big roll lid that can be fastened to Lulu cans) and dig a small circular hole in the lid** in such a size that the bulb is plugged in tightly. Insert the base of the bulb into the small hole. Take a piece of wire hunt and peel off the wire skin at both ends, wrap one end around the lamp base, and pierce a small hole through the side of the plastic cover with the other end.

Place the plastic lid over the can. Check that the bulb and battery are in close contact. At this point, the disposable flashlight is ready.

When using, use your thumb to press the wire threaded from the side wall on the weld that is not painted from the can, the flashlight will glow, and the thumb will jump off the wire, and the flashlight will go out, which is very convenient to use.

Elementary school students have a simple small hair to restore their sight, and a small production has a globe.

Bai starts by taking a ping pong ball.

du, draw the necessary zhi longitude and latitude, such as the equatorial north and south latitudes, the pole, the prime meridian and the 180 meridians, and so on.

After drawing the globe ball, we still have to make a hole in the poles, there is no hole on the earth, but our globe is fixed on the bracket, and we still need to use it.

A small fan, just a small motor, two size 5 batteries, some short wires, a solid plastic foam, a pair of scissors, some pieces of cardboard!

First of all, hollow out the solid foam, connect the small motor with a wire, stuff it into the foam (to keep the rotor shaft of the small motor leaking foam), connect the wire to the battery, also stuff it into the foam, cut the small piece of paper into rows with scissors, and put it on the rotor shaft of the small motor!

Sprinkler bottles. Just take a jar and poke a few holes in the tail.

Take an empty egg shell and coat it with wax (be thin).

Paint on it with a pointed object (to carve through the wax).

Put it in vinegar for a few hours, take it out and get rid of the wax.

The color of the carved place is darkened with acetate.

It's a small production!
