1) Organizational moment

Greetings of students.

Creating a favorable microclimate in the classroom. Class division into groups.

Reception "Say hello to elbows."

Descriptor:

• Each "number one" folds the hands behind the head so that the elbows are pointed in different directions;

• Each "number two" rests with hands in the hips so that the elbows are also directed to the right and left;

• Each "number three" bends forward, puts his hands on his knees and expose his elbows to the sides.

The name of the groups is "1", "2", "3".

Wish everyone successful mastering of the material in the lesson ...

Power Point presentation (slides)

Middle of the lesson

30 minutes

Active learning: Demonstration and modeling

II. Learning new material.

Aspect: conducting an experiment, processing information;

Stimulus: you will conduct an experiment and you will see the process of electrification by friction. Read the text, learn about the experience of Coulomb and write down the formula of Coulomb's law.

Tricative wording: development of communicative, information and technological competence

2.1 Conducting experiments. Objective: to develop practical skills and skills in conducting the experiment.

1 experience: Equipment: air balloon; Woolen fabric, polyethylene strips, paper strips.

 Take the air ball and rub it on the wool.

 Hold the ball to the paper strip. What do you observe? Describe your observations.

 Bring a loaded paper strip to the polyethylene strip, to a paper not loaded strip. Describe your observations. Make a conclusion. (What are the charged bodies, where is the electric charge located? What is called electrization?)

Formative evaluation (praise)

2 experience: Equipment: сomb plastic, сlean-washed head

A clean-washed head, comb several times with a plastic comb, what do you observe if you carry the comb to your hair?

Formative evaluation (praise)

2.2. Speech students with demonstrations. Students draw conclusions from observations.

Competence: informative, reflective

Objective: to develop to contribute to a clear formulation of their actions, to include knowledge and methods of action in the knowledge and methods of action already available to the system;

2.3. With the help of the presentation conclusions are summarized. Records are made in the notebook.

Competences: information, technological

The goal: to develop help to clearly formulate your thoughts.

Model Answer:

1. Electrification is ...

2. There are two types of electric charge: ...

3. The amount of electricity or electric charge is ...

4. The electric charge is denoted ... and measured ... .., is written by the formula ...

5. The law of conservation of charges asserts that ....

6. The law of conservation of charges is written by the formula: ....

2.4. For fixing, tasks that are projected onto the screen are considered.

Competence: informative, reflective

Purpose: Apply the knowledge gained in the new situation.

2.5 PHYMINNUT

Example of Active Relaxation Techniques

Reception «Earth, air, fire and water»

Increase the energy level in the classroom.

The teacher asks learners on his team to depict one of the states - air, earth, fire and water

Goal: Change of activity is the transition to more complex material.
