Organization.

І. Creating a classroom atmosphere of cooperation and mutual learning

Repetition of the last lesson:

1) Name at least two physical properties of hydrogen;

2) What is the relative density of hydrogen in the air?

3) Give one example of hydrogen production in the laboratory;

4) High-quality reaction to hydrogen.

5) Draw a picture of the installation for the production of hydrogen in laboratories.

(f) Formative Assessment Process

To acquaint students with the topic of the lesson and learning objectives:

Know the percentage of oxygen in the composition of the air and the earth's crust

After reviewing the objectives of the training, assessment criteria are developed together with the students.

Possible evaluation criteria:

- knows the percentage of oxygen in the composition of the air and the earth's crust;

- knows and explains the production, properties and use of oxygen.

Theme of the lesson:

Oxygen, production, properties and application.

35-38 min

Ask students to write the equations for the following reactions:

• hydrogen + oxygen

• hydrogen + chlorine

• hydrogen + sulfur

• zinc oxide + hydrogen

• potassium + hydrogen

• sodium + oxygen

• calcium + oxygen

• hydrogen sulfide + oxygen

• methane (СН4) + oxygen

Differentiation - how do you plan to provide more support? What tasks do you plan to set for more capable students?

Grading - how do you plan to check students' level of learning?

Health & Safety

Differentiation will be used when dividing into groups for working with text.

Mutual evaluation, formative evaluation by criteria. The teacher checks the written work by the success criteria.

Students will work in pairs, move around the class and will be active.

The assignments in the evaluation sheet are made out in an accessible font that does not harm the eyes.

Lesson reflexion

Were the objectives of the lesson / learning objectives realistic?

Have all students reached the DH?

If not, why not?

Is the differentiation correct in the lesson?

Have the lesson temporal stages been sustained?

What were the deviations from the lesson plan and why?

Use this section to reflect on the lesson. Answer the most important questions about your lesson from the left column.
