Material preparation:
There are 1 carton with lid, 1 cardboard (such as cigarette cases or playing cards), 4 identical rubber bands, 1 coin, pins, small plastic sheets, scissors, ruler, pen and glue.
Production process:
1. Cut a piece of paper 4 cm wide from the cardboard, and the length of the paper is twice the width of the carton; If the length of paper is not enough, you can cut two pieces of paper as wide as the carton;
2. Fold the paper into the shape of the Yangtze River Delta with the side length of 1 cm, and glue the extra side to the other side;
3. Put the bottom of the paper box up, put a coin in the center of the paper box and draw a circle along the coin. Use a pin to punch a hole along the round hole to make the round part fall off;
4. Glue two triangular pieces of paper to both ends of the paper box (the perforated side) to make a string horse (piano frame);
5. Put the rubber band on the paper box and gently stir the rubber band with a small plastic piece to make a sound;
6. Adjust the tightness of the rubber band so that the rubber band emits four different syllables of "1, 2, 3, 4" respectively.
Precautions:
1. In order to fold the hard paper into a diamond, you can first draw a straight line on the paper with a ruler and divide the paper into four equal parts, with a width of 1 cm and a constant length; Draw along a straight line with a ruler and a pin, so that the paper can be easily folded along the trace;
2. In order to prevent the rubber band from sliding, four small gaps can be cut on the bracket respectively.
Two, the production methods of animal husbandry sheng:
Material preparation:
Bamboo or hollow plastic pipe, plasticine or clay, adhesive tape, scissors.
Production process:
1. Cut bamboo or plastic pipes into different lengths (5cm to 20cm).
2. Put plasticine or clay into the end of the pipe, or seal the end with adhesive tape.
3. Arrange according to the length of the pipeline; The shortest is at one end and the longest is at the other. Arrange the edges without plasticine or clay, and then fix the arranged pipes with adhesive tape.
4. Put the open side of the tube on your lower lip, and then blow gently to let the air flow through the nozzle.
