What to do in junior high school science and technology production, suitable for science and technol

Materials: bamboo, wire, plastic film, waste towels, grease (or other fuel) tools: knives, transparent glue, pliers,

Take a 2-meter-long bamboo, cut it into thin strips with a knife, bundle it into a circle, and connect it with a very fine wire to use as a heating support. Find another plastic film (thin, light) to enclose the same size as the bamboo ring, the cylinder is high meters, the top of the tube is also covered and sealed with film, and the bottom of the film is glued with transparent glue with the bamboo. Find another waste towel 20cm*20cm, dip a little kerosene (pour grease before flying), and the Kong Ming lantern will be made.

The next step is to fly, first of all, to choose a spacious, surrounded by no tall trees and wires in a place, the viewing effect of the night release is very good, first pour some grease on the towel when flying, put the towel in the center of the wire bracket, one person lifts the film of the Kong Ming lantern from above, the other person lights the towel, the towel burns to make the air in the film heated and light, the person who carries the lantern feels that the film of the Kong Ming lantern expands and becomes lighter, (it is more dangerous at this time, it is easy to ignite the film if you don't pay attention.) If there are tree branches hanging the lantern in the flying field, a fire will occur, so be careful) Immediately and slowly released, the Kong Ming lantern slowly and automatically lifted into the air. After reaching a certain height, the air is thin and the combustion gradually extinguishes, which is not enough to support it to continue rising, or the fuel is burned out, and the Kong Ming lantern has no power to rise after it falls.

Homemade soap paper making materials and tools:

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.

Note 1: Security issues.

Both parents and schools are concerned about the safety of students, and some schools do not carry out manual classes because they cannot guarantee the safety of students. Now that the school has carried out manual research and proved that it has been able to effectively solve the incident of children's safety.

Before the teacher formally lectures, the teacher must tell the children not to mess with scissors and other sharp objects. At the same time, students should also be taught how to use glue and paper to prevent them from drinking glue as a drink.

Note 2: Emphasize the discipline of manual classes.

Many children are reluctant to attend craft classes and therefore do not follow the discipline of craft classes. Every child has scissors in their hands, and if two classmates who don't follow the discipline in the classroom fight, the consequences will be unimaginable. Therefore, the teacher must emphasize the classroom discipline many times before the class, so as not to let the child have an accident because he does not follow the classroom discipline.

1. The cardboard obtained from the waste carton is cut as our handmade material, which is absolutely environmentally friendly. Parents who often buy things online can now use those discarded express boxes. 2. Prepare a drink bottle.

3. Print out the parts of the accessories (drawings are attached).

When washing clothes, some remaining soap bars and crumbs, continue to use both fragile and difficult to use. In order to make the most of these leftover soap heads, the ordinary laundry brush was modified and the desired effect was achieved.

Modified materials: a washing brush, a thin iron sheet (preferably aluminum or copper), and a few small nails.

Method: Cut the thin iron sheet into 3 cm wide strips, then use small nails to nail around the washing brush to form a small container (soap dish) on the top of the washing brush, and then use an awl or hand drill to drill some holes between the brown hair tufts of the washing brush. Then make a lid slightly larger than the top container out of a thin sheet of iron to cover the soap dish.

The practice of junior high school science and technology works is as follows:

1. Take a 250ml empty beverage bottle and cut off the top half of the bottle.

2. Divide the cut part into 8 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 foam fruit net sleeve 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 table tennis ball, cover the bottom surface 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 modification, a homemade shuttlecock was completed.

Introduction to the small production of science and technology:

The characteristics of small science and technology production are rich in science and technology, simple structure, easy to find materials, easy to process, less cost, and can be completed independently, especially suitable for students, which can cultivate students' creative ability, thinking ability and hands-on ability. Teachers can appropriately inspire students to create high-quality small productions.

Small scientific and technological productions can be divided into two types: imitation type and creative type. The imitation type is mainly formed by imitating others, and most children's science and technology small productions start from imitation. Start by imitating, and gradually become interested, you can create your own creation.

The creative type refers to this kind of small production, which is mainly created by the children themselves. For example, making Shimin himself to build a car and so on. There are high and low levels of creation, and the average child's science and technology production is a primary thing, so it can't be too demanding.

The third-grade science and technology mini-production practice is as follows:

It can be chosen according to the student's interests and abilities, such as small windmills, solar toys, etc. Here's how:

1. Choose the right theme

Interest-driven: Students should choose appropriate topics according to their own hobbies and interests.

Teaching requirements: The theme should not only be interesting, but also meet the teaching requirements assigned by the teacher.

2. Determine the theme goals and implementation steps

Goal-oriented: Identify thematic goals, such as scientific principles such as solar energy, or specific skills such as handicraft.

Step splitting: The entire production process is broken down into several steps and broken down into simple and easy-to-understand tasks according to the age of the students.

3. Use materials and tools to make it

Tool use: common tools such as scissors, tape, screwdrivers, straws, wires, and recyclable materials such as waste items.

4. Production and optimization

Production process: According to the pre-arranged steps, the production of each link is carried out.

Optimization and improvement: In the process of production, according to the actual situation, the parts that are not suitable or have problems can be fine-tuned, corrected and innovated.

5. Practical application and display

Practical application: After completing the production, apply it to real life or scientific and technological experiments to further appreciate its significance and value.

Display: It can be displayed in the form of a school evaluation display, a classroom display or an interactive science and technology corner display to improve the self-confidence and attention of the makers.

6. Safety precautions

Storage: Students need to take good care of their own production materials and equipment in accordance with the rules of classification and personal property management, especially when it comes to battery energy, etc., to pay attention to safety.

Assistance and guidance: Teachers or parents should strengthen guidance and assistance, and pay attention to monitoring the hygiene and safety of the production process.

The above brief steps can be used as a reference, and the science and technology mini-production of Year 3 students should be simple and easy-to-do, encourage students to experiment and innovate, and give full play to students' imagination and creativity.

Disc into pen holder.

Tools: white latex, 4 CDs.

Production: 1Glue one disc vertically with white latex to the quarter of the other disc [as long as it is between the edge of the disc and the middle hole]. 2.Paste it into a square like this.

Extension: If you want the bottom, you can glue the 5th disc under the square.

Usage: The pen can be inserted anywhere.

The box makes a CD rack.

Tools: White latex, box [as long as it's bigger than a CD].

Production: 1Subtract the side of each box [width greater than cd]. 2.Glue together with white latex.

Extension: 1It can be formed into a square or other shapes.

2.If you make it too small, you won't be able to support the CD, so flatten the box, cut it to the size of the side of the model, and glue it to increase the side gravity. 3.

You can also wrap a piece of book paper on the outside to add aesthetics.

Usage: Just put the CD in it.
