Learning Objectives

10.2.2.1 – to apply the ideal gas law and distinguish the gas law graphs;

Lesson Objectives

According to the lesson theme

Students will

·         Recall and solve problems using the equation of state for an ideal gas expressed as рV = NRТ.

Assesment criteria

• In order to achieve this learning objective, learners will have to,
• Derive the equation of state for an ideal gas
• Analyze and compare change of macroscopic parameters for ideal gas
• Apply equation of state for an ideal gas during problem solving

Language Objective

Students will:

·         Explain orally the equation of state for an ideal gas expressed as рV = NRТ

·         Use new vocabulary accurately in a way which demonstrates understanding.

Subject-specific vocabulary & terminology: pressure, Pascal, volume, temperature, Kelvin, molecule, mole, gas constant (R), molar volume at stp, average translational kinetic energy, heat, random, torr, randomly.

Useful set(s) of phrases for dialogue/writing:

Heating the... increases the kinetic energy of the particles.

Value links

1. The teacher creates a favorable, friendly atmosphere for interaction

2. The teacher and students together determine the goals, criteria, rules of working in groups.

3. A student assesses specific situations from the legal, social, economic, political, environmental, technological point of view

Cross curricular links

Mathematics: Solving not so straightforward equations requires some mathematical skills

Chemistry: Avogadro constant and Moles quantities also described in Chemistry subject.

Previous Learning

Students already studied kinetic theory model, Brownian motion and the equation of the state an Ideal Gas

Beginning

Start:         0-5 min

(W) Greeting.

Teacher greets and registers students.

(W) Review of previous lesson. Ask learners.

Questions:

What do you mean by Avogadro's number? What is its value? How do you calculate the Molar Mass of a Substance?                                                                                       What is the absolute zero temperature? Why is it called that? What is the physical meaning of temperature?

Explain the lesson topic, learning and lesson objectives.

State the new lesson and tell students the importance of lesson.

Middle (Main activities)

5-15 min

15-35 min

(G) Work with resource Bilimland.

What is the equation of state for an ideal gas?

A gas whose molecules have zero volume and which do not interact with one another, apart from the moments when they collide.

What is the equation of state for an ideal gas?

Activities 1-2 (Bilimland-3)

(G) Propose students to independently derive and explain the equation of state for the ideal gas. Individual students are invited to find brief information about the work of Clapeyron.

;

;     N=ν; 

;   

R =k=8,31 Дж/моль·К.

The gas equation of state links the basic quantities that characterise a gas. The equation is often applied in the following form: pV=νRT

The Clapeyron equation combines all the gas parameters.

(W) Students and teacher will solve one or two examples.

Students will individually solve problems that require the application of formula: (pV = NRT);

(I) After which teacher gives worksheet task to student to individually complete. Call the weak students on the board to solve the problems.

Check the students’ answers and give the feedbacks to them.  Individual work with weak students. Give the extra worksheets to the students who solved all the problems.

Criteria: To achieve the learning objective, learners must correctly solve at least five out of six problems (83 %) on ideal gas laws.

End (Plenary)

35-40 min

Teacher facilitates discussion with students on lesson:

Reflect on lesson objectives—achieved or not; etc.

Teacher issues the homework assignment.

Additional Information

Differentiation

Besides, provide more time for second language differentiation.

Students will work in cooperative learning groups and individually.

Video clip, written and oral expression will be utilized throughout the lesson.

In addition, higher level questions/tasks specifically intended for more capable learners will be provided during/after lessons.

.

Homework: Students will work in groups to complete worksheet on gases and present their answers during the next lesson.

.

Assessment – how are you planning to check the students’ learning?

Students will solve

    problems that require

    the application of

    formula: pV = NRT;

Cross-curricular links, Health and Safety, Links with ICT, Links with Values

Students can visit:

Edmodo.com in students learning center

Health and Safety—Ensure that classroom is appropriately conditioned in terms of ventilation, heating/cooling, lighting; etc.

Internet will be utilized to present video clip on the three gas laws, PowerPoint slides throughout.
