A strategic study on how to make the primary school science classroom full of childlike fun

You can refer to the classes abroad.

Summary. Hello, I think I can choose a simple "electrostatic experiment" as a teaching activity in primary science class. From the three perspectives of device, principle and function, the details are as follows:

1. Device: 1a small plastic plate (which can be the kind on the wash basin), or the plastic casing of the charger; 2.

a woolen thread (or nylon rope); 3.Small pieces of paper or thin pieces of iron. Second, the principle:

When we comb our hair or get dressed, static electricity is generated. Similarly, when we quickly pull the yarn across the surface of the plastic plate, we also carry some electrons away from the board, leaving some electrons on the board. This makes the plate negatively charged.

When we bring negatively charged plastic sheets close to small pieces of paper or thin pieces of iron, they are also negatively charged, because otherwise neutral objects will repel each other when they are charged with the same kind of charge. 3. Function: Through this experiment, primary school students can intuitively feel the phenomenon of static electricity and understand what happens when an object is charged with the same kind of charge.

At the same time, it can also cultivate their experimental spirit and curiosity about scientific phenomena.

Choose an experiment that you are most familiar with and use it in the teaching activities of primary school science classTalk about how to use it to cultivate primary school students, how to use it to train primary school students, starting from the device, principle, and role.

Is this kind of topic a lesson plan or not?

Hello, I think I can choose a simple "electrostatic experiment" as a teaching activity in primary science class. From the three perspectives of device, principle and function, the details are as follows: 1. Device:

1.a small plastic plate (which can be the kind on the wash basin), or the plastic shell of the charger; 2.a woolen thread (or nylon rope); 3.

Small pieces of paper or thin pieces of iron. 2. Principle: When we comb our hair or wear clothes, static electricity will be generated.

Similarly, when we quickly pull the yarn across the surface of the plastic plate, we also carry some electrons away from the board, leaving some electrons on the board. Resistance to simplification will make the plate negatively charged. When we bring negatively charged plastic sheets close to small pieces of paper or thin pieces of iron, they are also negatively charged, because otherwise neutral objects will repel each other when they are charged with the same kind of charge.

3. Function: Through this experiment, primary school students can intuitively feel the phenomenon of static electricity and understand what happens when an object is charged with the same kind of charge. At the same time, it can also cultivate their experimental spirit and curiosity about scientific phenomena.

Another 1Elementary school students can do this experiment on their own, so that they feel that they have mastered some "magic"; 2.Elementary school students can try to replace wool with different materials to see what will happen; 3.

It can be further extended to explain the application of electrostatic flying mountain chairs, electrostatic stickers and other related applications, so as to stimulate the interest of primary school students in scientific and technological innovation.

1. Guide students to visit science and technology exhibitions and science books. 2. Tell more stories and legends related to scientific inventions. 3. Lead students to do experiments, small productions, etc

They are the most admired Chinese female scientists, how to cultivate children's interest in science.

Prepare more science stories and be able to do some experiments in class.
