Key competences

• communication in the mother tongue;

• communication in foreign languages;

• mathematical competence and basic competences in science and technology;

• digital competence;

• learning to learn.

Criteria for success
The student will learn:

• to ask and answer questions from colleagues about the chemical laboratory;

• to consolidate the material from the lesson: „Subject assessment principles and educational requirements”, „Everyday chemistry”, „Chemistry lab pt 1” and „Chemistry lab pt 2”;

• to consolidate vocabulary related to the subject of the chemical laboratory.

Methods/techniques

  • discussion.

• programmed

  • with computer;

  • with e‑textbook.

• practical

  • exercices concerned.

Forms of work

• individual activity;

• activity in pairs;

• activity in groups;

• collective activity.

Teaching aids

• e‑textbook;

• notebook and crayons/felt‑tip pens;

• interactive whiteboard, tablets/computers.

Before classes

1. Students will read the abstracts „Subject assessment principles and educational requirements”, „Everyday chemistry”, „Chemistry lab pt 1” and „Chemistry lab pt 2”. They prepare to work on a lesson in such a way that they can be summarized in their own words, solve tasks and take part in the discussion.

2. Volunteers get acquainted with the content of the abstract „Subject assessment principles and educational requirements” and prepare a knowledge quiz for their colleagues.

Lesson plan overview

Introduction

1. The teacher defines the goal of the lesson and sets the criteria for success together with the students.

2. The lecturer reminds the participants of the classes what subject area the lesson will concern.

3. The teacher informs the students that as part of the warm‑up before the repetitive lesson they will solve the quiz prepared by their colleagues. Students answer questions on a first come, first served basis and earn points. The student with the most points is rewarded for activity.

Realization

1. Students work in four groups. The teacher informs them that they will listen to the recording „Everyday chemistry”, and their task will be to prepare questions regarding the content of the recording for another group. He asks pupils to take notes while listening. After playing the recording, the teacher sets the time to prepare the questions. Then the groups exchange questions and prepare answers. Group representatives present their proposals, and the authors of the questions verify the answers. The teacher watches over the correctness of the task.

2. Students still work in groups. The teacher asks each team to prepare a crossword related to the issues from the abstract „Chemistry lab pt 1 '.

3. After the preparatory phase, there is a competition phase. Groups are exchanged with crosses. The teacher controls the course of the game by checking the correctness of the answer. The group that will solve the task correctly will win the competition and should be rewarded by the teacher with the appropriate grade.

4. Students independently solve an interactive task with an illustration.

5. The teacher displays an interactive board with individual stages of the scientific experiment. Students in pairs solve the task – organise the steps, and then the willing/selected students present the solution on the board.

6. Expanding and enriching English vocabulary in the issues covered in the lesson - students perform language exercises included in the abstract. The teacher makes sure that the tasks have been correctly completed and gives feedback.

Summary

1. The student indicated by the teacher sums up the lesson, telling what he has learned and what skills he/she has been practicing.

Homework

1. Make at home a note from the lesson using the sketchnoting method.

The following terms and recordings will be used during this lesson

Before you begin solving the exercises, review abstracts „Subject assessment principles and educational requirements”, „Everyday chemistry”, „Chemistry lab pt 1” and „Chemistry lab pt 2” to recall the most important information and vocabulary. Then you will be able to check your knowledge. Good luck!

• Chemistry is not only a school subject – it is present in every area of our lives. It has a long and interesting history.

• Chemistry is a science that investigates the composition and structure of substances, their transformations and conditions affecting the speed of these transformations.

• In the chemical laboratory, the rules of health and safety regulations (health and safety at work) must be observed.

• Special glass, dishes and laboratory equipment should be used for chemical experiments.

• When planning the empirical test, you must remember to use reagents reasonably in order to reduce the amount of waste generated.

• Chemical experiments should be performed on a laboratory table in accordance with laboratory work techniques, keeping in mind the principles of health and safety and order.
