    mading small balance

    This Reminder: Must be performed with the help of parents!

    1. Cut the three -in -board plate into A, B, C, D.

    2. Open at the bottom of B. C and d's middle opening.

    3. Insert the three thin strips as shown in the figure.

    4. Nail A in the middle and upper part of B, but be careful not to nail, you must be able to move freely.

    5. Trimmid the crescent -shaped benchmark with the three -in -board board and the scale.

    6. Then a small strip is fixed on A with universal glue, as shown in the figure.

    7. Two round pieces, equal size.

    8. Four small holes on each.

    9. Cut a small slot on each side of A.

    10. With a thin line, the balance is made.

    It you can use your own imagination, decorate the small balance, and you can also use the experiment as a small decoration. It is really good!

    The walnut shell small turtle

    . The production materials and tools

    Star, calendar paper, glue, color pen, walnut, etc.

    . The production method

    1. The walnut is carefully split from the middle, divided into two halves, and takes half of the complete non -destructive (Figure 1).

    2, take the old calendar paper (or other thick white paper), cut the turtle's head, feet, tail and body, the size of the body is preferably put into the walnut shell.

    3, fold the head in the dotted line and paste the glue (see Figure 3).

    4, stick the walnut shell to the body, and then paint the eyes on the head. Such a lifelike little turtle is done.

    The clean rubber rubbing with a brush

    This writing the wrong words, rubbing with rubber. After rubbing, there will always be a lot of debris on the paper. Whether it is shot or blowing it with your hands, it is unsanitary and troublesome. Making a clean rubber wipe will not be so troublesome.

    Materials: big rubber, waste brush.

    Tools: scissors, glue.

    production method:

    1. Dig a shallow small round hole on the rubber end 2. Remove the pen's pen head and wash and dry it.

    3. Cut off the tip of the pipe to make it a small brush

    4. Embed the brush head into the small round hole of the rubber and stick it with glue

    , good, clean the rubber. Whenever you rub the rubber, you can gently "scan" the debris on the paper with a brush, and then pour it into the waste basket.

    n only small square mirrors and a hard cardboard as large as the two sides. If your small mirror is ten centimeters long and seven centimeters wide, so you should prepare a hard cardboard with a wide 4 × 7 = 28 cm wide. The length of the cardboard can be determined according to the conditions. The cardboard is longer, and the subtastic telescope can be done higher.

    In three parallel lines on the cardboard. Like the chart, the distance between each line is seven centimeters. Cut the blackened part. Use a knife to draw a trace along the dotted line (be careful not to scratch). Then, use the table to fold it to make a rectangular box and stick it with cowhide paper.

    This with white gel cloth sticks to the small mirror as well as in the figure below (to make the interlaced angle between the small mirror and the long carton is equal to 45 °). The small mirrors are parallel parallel. In this way, a subtitum is made.

    If the small mirror in your hand is less than ten centimeters long, you can calculate the size of the carton according to the Pythagorean theorem, the condition is to ensure that the angle between the mirror and the carton is 45 °. It is very interesting to watch the scenery outside the window with a subtastic telescope, and it can also be used to catch and seek. Of course, people's manufacturing submarines are mainly for scientific research and defense. Scientists use the subtra level to observe the launch of the rocket in the basement; when conducting atomic physical experiments, scientific researchers can observe those radioactive dangerous experiments with a thick protection wall with a thick protection wall. When the submarine sails underwater, it must also use the subtraction to observe the situation of the sea surface.

    The inventive invention of the subtraction is no longer checked. The earliest ancient book in the world recorded the principle of subtraction camera is the "Huainan Wan Bi Shu" in my country in the second century BC. The book records such a paragraph: "Take the high mirror high suspension and set the water disk under it, then see the neighbors."

    In ancient times, under the eaves of some ancient temples in my country, often There is a large bronze mirror tilting. If a pot of water is placed on the ground within the temple gate, it is the simplest mirror to make the simplest subtitum. Essence
