The first year of junior high school science and technology small production, 1 6 grade science and

Innovative gadget production method 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 for crafting:

Hygroscopic white paper, small pieces of soap, a brush and disposable beverage cans.

Production method: first chop the soap and put it in the jar, put the cup on the stove after filling the 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.

It can be a dirt **... Or a globe. Soil ** Material:

Two paper cups, a long rope. Soil ** production: Make a hole in two paper cups, no need to be too big.

The rope is threaded through two paper cups. Then help make a hole in the paper cup.

Add some oil and look for it.

Such as windmills, waterwheels, simple transmission devices, etc. This can cultivate children's interest in mechanical principles and also experience the joy of making. 2.

Simple circuits and electrical appliances: such as simple circuits composed of light bulbs, batteries, and wires; Simple switches and electric bells, etc. This allows children to get hands-on experience with how circuits and appliances work.

3.Optical toys: such as telescopes, magnifying glasses, kaleidoscopes, etc.

By making these toys, children can deepen their understanding of optical knowledge and cultivate their curiosity about science. 4.Simple sound device:

Such as interestingly audio, gramophone, ** machine, etc. This allows children to understand the mechanism of the generation and propagation of vocal sounds. 5.

Simple astronomical models: such as sundials, constellation disks, etc. By making these models, children can deepen their understanding of astronomy.

6.Biological experiment equipment: such as microscopes, biological incubators, etc.

This can cultivate children's interest in biological sciences and experience the scientific knowledge of life through practice. 7.Science Toys:

Such as floating toys, bouncing toys, spinning tops, etc. These toys not only have entertainment functions, but also can reflect certain scientific principles and stimulate children's curiosity and spirit. These small technological creations can not only deepen children's understanding of relevant knowledge, but also develop their hands-on and creative skills.

The problems and difficulties faced in the production process can also cultivate children's imagination, perseverance and innovative spirit. I have a strong interest in science and technology, which is also a good foundation for future studies. If you need specific small production steps and materials, you can always ask.

I will provide detailed explanations and references. Let's work together to cultivate children's enthusiasm for technology and creativity!

How to make an aerodynamic car.

a) Materials and tools:

131 electric motor, 4 toy wheels, propellers, motor bracket (2mm paulownia wood chips), body (300mm paulownia wood strips), battery clamps, axles (2mm steel wire), several wires, front and rear wheel brackets, bearings (4 rivets), etc.

2) Production method:

1. Body: The body is 4x6 with 300 mm paulownia strips, which should be as straight as possible and not twisted.

2. Front and rear wheel brackets: It is best to have ready-made timbers, if not, make them with wood chips or bend them with iron sheets. The front wheel bracket is made of 2mm bicycle wire.

3. Install wheels: pay attention to reduce various resistances, and it is best to use rivets instead of bearings.

4. Motor bracket: The motor bracket is bonded with wood chips. Pay attention to the size of the bracket, the height is not enough, the propeller will hit the body, the bracket is too high, and it is easy to overturn. Some reinforcing strips can be added to the bonding to improve the strength of the car.

5. Install the motor: glue the motor with 502 glue and install the propeller. The battery clamp is glued to the body with sponge double-sided tape. Connect the wires on the battery clamp to the motor, make a self-made switch, and the whole model is installed.
