Chemistry of non-metals-SUBSTANCES AND their PROPERTIES - LESSON PLANS for CHEMISTRY class 11 - lesson plans-lesson plans-author's lessons-plan-lesson summary - chemistry

The purpose of the lesson: to teach you to make short reports based on the main characteristics of non-metals, working with additional scientific and educational literature; to expand the theoretical knowledge of the material being studied and the Outlook of students.

Equipment: student messages in the form of abstracts or thematic Newspapers.

Lesson progress

I. Organizational moment

Setting goals and tasks for the lesson.

Recommendations for the teacher

Students took the topics of messages in the first lesson of studying the topic "Substances and their properties". The teacher should familiarize himself with the content of students ' abstract messages and make a plan to listen to them consistently:

1. Halides are elements of group VII, the main subgroup. Simple substances and compounds formed by these elements. Application.

2. Chalcogenes are elements of group VI, the main subgroup. Simple substances and compounds formed by these elements. Application.

3. Elements of group V, the main subgroup, simple substances and compounds formed by these elements. Application.

4. Elements of group IV, the main subgroup, simple substances and compounds formed by these elements. Application.

In the presence of reagents, it is desirable for students to experimentally confirm the chemical properties of simple substances — non-metals and some compounds formed by these non-metals (especially poor-quality reactions to anions).

Given the volume of material, each message is prepared by two or three students and jointly defended.

II. Conducting a lesson-seminar

Listen to and discuss student messages on the following plan:

1. History of discovery of non-metals. Why is this name given? Being in nature, receiving.

2. The structure of atoms, the degree of oxidation.

3. Features of physical properties ofSTV PRof other substances. Allotropic changes. Chemical bond, crystal lattice.

4. Features of chemical properties.

5. Critical applications in pure form and in the form of compounds.

III. Summarizing the lesson results

The teacher gives an appropriate grade and invites some students to continue working on the topic and speak at a scientific and practical conference (if they are held at school).

IV. Homework assignment:

Complete a task for options on separate sheets for evaluation. § 19. B—1: № 8 (2), № 9 (1), task 14; B—2: № 8 (4), № 4 (2), task 15.
