What should I do with science production?

Find a square cardboard box, remove a surface, this surface is replaced with plastic film, and the ** on the opposite side of the surface is pierced with a needle,,, completed, this is a small experiment of small hole imaging.

Small productions that use scientific principles, such as the principle of thin shells of eggs, can be used, and so on.

Scientific small production is waste utilization, using waste to make some valuable small objects, such as decorations, etc., the common practices are as follows:

1. Prepare materials and tools for making rocket and space models, such as a beverage bottle, a number of colored paper, a pair of scissors, a piece of tin foil, a number of corrugated paper, and paint.

2. Cut off the bottom of the bottle, leaving a section of the bottle mouth, about 20 cm, as the body of the rocket model, and make a hole near the bottle mouth.

3. Make a sharp taper with corrugated paper and put it on the mouth end of the beverage bottle as the head of the aerospace model.

4. Use paint to color the beverage bottle, as well as corrugated paper as the pillar of the base of the space model, and the rocket head can be wrapped in tin foil without paint.

5. Cut four openings at the low end of the beverage bottle, load the corrugated paper, and then glue the beans as a decoration and add color.

6. Equip the rocket model with a tail, you can tie it into a bunch with thin strips of paper and stuff it into it as a tail, and the super good-looking rocket model made from a drink bottle is ready.

Scientific small production: it is waste utilization, using waste to make some valuable small objects. For example, to make an "exact bookmark", in the past, the bookmark could only be accurate to which page, and the exact bookmark could be accurate to which line; Method:

Use a discarded toothpaste box to cut a long bookmark and cut a semicircle on it to hang on a certain page of the book; The bookmark is covered with a paper ring that can be moved up and down, the paper ring is fixed with transparent glue, and an arrow is drawn on it, and it is done.

Scientific small production: use the items that are easy to get around you, combined with certain scientific principles, to make a new and valuable object, and sometimes it may be a prop that can explain the scientific principle.

Such as: fruit battery, water rocket, kaleidoscope and so on.

Hope it helps!

rnThis is a simple way to make a small arrow, when the small arrow takes off in the air, you can share the infinite fun of scientific experiments and a strong interest in the mysteries of science.

Materials: Yellow cardboard; white foam board; Straw; double-sided tape; Scissors.

Experimental principle: The rocket uses the recoil force generated by the high-temperature and high-pressure gas generated by the combustion of internal fuel from the tail to move forward. When our cupola arrow blows into the straw, the air flow exerts a forward momentum on the arrow, causing the arrow to take off into the air.

Precautions: Use scissors when making cupola arrows, please pay attention to safety. Experiment Steps:

1.Cut out a small fan-shaped piece of paper from the yellow cardboard.

2.Glue a strip of double-sided tape on one side of the fan-shaped piece of paper.

3.Roll the fan-shaped piece of paper into a cone and glue it firmly with double-sided tape.

4.Cut a small strip of paper from the yellow cardboard.

5.Roll the long strip of paper into a cylinder and put it into the cone made in front.

6.Connect the cone and cylinder with double-sided tape.

7.Cut 4 small strips from the white foam board.

8.Fix the foam strip at the end of the cylinder with double-sided tape, and the 4 pieces of foam are evenly distributed.

9.Cut 4 small trapezoidal pieces of paper from the yellow cardboard.

10.Use double-sided tape to fix the trapezoidal small pieces of paper at the end of the cylinder, and distribute the 4 small pieces of paper at intervals with the 4 foam strips.

What is this for, to make one for you?
