What are the small production inventions for middle school students?

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

When I'm at home, I always take the initiative to do whatever I can, such as washing dishes, mopping the floor, and wiping the table. What I am most afraid of doing is mopping the floor, a few houses are dragged down and my hands grind out blood blisters, cabinets, tables and other narrow places are not easy to mop, and they are not clean. Once, while mopping, I thought how nice it would be if I had a pair of mop shoes to wear on my feet and mop the floor!

So, I designed a mopping tool that was both lightweight and didn't bend over – the shoe flip-flops.

Production method: 1. The slippers should be larger than the shoes you usually wear, so that they can be easily worn on the shoes.

2. Use rag strips as mop strips on the soles of shoes, and nail a thick layer of plastic bottom on the mop strips, which is both waterproof and durable.

3. Use a cloth shell and a tarp to make an upper, and install a zipper on the back root of the upper, which is easy to put on and take off. Connect the upper to the sole and the slip-flop is ready.

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!

1.Junior high school students' small production (small inventions) is simpler!!

2.Small inventions made by middle school students.

Answer: Teach you to do only four things 1Screen:

Art and handicraft: scissors, colored pencils, bamboo (bamboo strips can), scotch tape, utility knife, pencils, etc. A: Cut the bamboo into two bamboo strips of toothpick thickness, and then cut it off without 8cm, a total of 5, of course, if you want the screen to be large, you can add more to the length and quantity of the bamboo strips.

B: Look for colorful cardboard such as wall calendars with landscape paintings.

5.Tell me about the inventions and small crafts of middle school students.

Answer: Science Invention Science Invention Water Truck I can! Find six sturdy sticks and two axle wheels (other wheels are fine) and load a water lift truck according to the diagram.

Hang an iron hook on the head of the car. When carrying water, hang the bucket on the hook and push the cart with your hands. This kind of car can also be used to transport coal or other things without much effort.

Use of water trucks.

To make a periscope, you only need two small square mirrors of the same size and a piece of cardboard. If your small mirror is ten centimeters long and seven centimeters wide, then you should prepare a piece of cardboard with a width of 4 7 = 28 centimeters. The length of the cardboard can be decided for yourself according to the conditions.

The cardboard is longer, and the periscope can be made taller. Draw three parallel lines on the cardboard, the above is the answer to your consultation, if there is no problem, evaluate it on the right, and end the consultation in the upper right corner.

Questions. Are there any steps in the details?

The steps are already detailed.

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

The process of making a globe The whole process is a four-step process: Draw a map of the world on the surface of a full table tennis ball. At both ends and a quarter of the thin iron sheet, drill a small hole and bend it into an arc as a globe support.

Cut a piece of the ball with a diameter of 20 mm on half a ping-pong ball and stick it to a piece of log. Grind a 4 mm diameter strip of wood with sandpaper at one end into a smooth log strip with a diameter of 3 mm, and glue it to the center of the sphere as a bottom pad. Attach the bracket to the base with a pin.

Thin steel wires are passed through the center of the North and South Poles and fixed at both ends of the bracket so that the globe can rotate freely around the axis.

This room is easy to make. Yes.
