Theme of the lesson

Thermodynamic work

Learning objectives that are achieved at this lesson (Subject Program reference)

·         To use internal energy formulas of the monatomic and diatomic ideal gas in problem solving

Lesson objectives

·         Define work as the transfer of mechanical energy to a system

·         Explain that just like a force results in displacement so pressure results in volume change.

·         Distinguish between work done by the system (w = negative) and work done on the system (w = positive)

Success/Assessment

Criteria

·         Give and exam quality definition of work in thermodynamics

·         Describe the work done on/by an ideal gas

·         Explain how we can calculate the work done on/by an ideal gas

·         Solve problems on work in thermodynamics

Language objectives

- put technical terms into context

- define the terms:

Type of differentiation

Different questions are asked to students differentiating according to their cognitive ability. Gifted students will be expected to answer the advanced questions and challenged students may answer standard level questions.

Values instilled at the lesson

Life Long Learning, Academic Integrity and Transparency, Respect for Self and Others

Values are implemented through the ethical use of thermodynamic systems by humans.

Preliminaries

Setting the mood. Greet students.

“Good morning everyone, please sit down.”

Introduction

The teacher will ask questions to determine what the students already know about work.

What is work?

How can we calculate work?

What is the difference between work done on the system and work done by the system (compare it to work done by positive and negative forces (i.e. friction force) in mechanics)?

What does the area under a P(V) graph give us?

Part 3

(5+5 min)

Part III Discovery learning

1.      Every student will use Bilim-land to work through the topic ‘Work in thermodynamics’

2.      There are 3 pages, students should watch every video and answer all questions

Part 4

(12 min)

Part IV  Multiple Choice questions

Every student will receive a worksheet with structured questions and they should solve it individually

.

Part IV  Solve structured questions

Every student will receive a worksheet with structured questions and they should solve it individually.

Worksheet 1

Worksheet 2

End

(2 min)

At the end of the lesson students reflect each student writes on a sticky note:

-       What they have learnt

-       What remained unclear

-       What should they work on

All problems that are not completed will be homework.

(Optional)

Worksheet 3 as a homework

Differentiation – how do you plan to give more support? How do you plan to challenge the more able learners?

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

Health and safety regulations

Different questions are asked to students differentiating according to their cognitive ability.

Gifted students will be expected to answer the advanced questions and challenged students may answer standard level questions.

Oral questioning and feedback.

The teacher will check the quality of answers on the students’ worksheets.

There should be good ventilation in the classroom

The temperature in the classroom should be appropriate for effective learning to take place, around 25°C.

Students should be reminded to adhere to all safety rules in the laboratory.

Reflection

Were the lesson objectives/learning objectives realistic? Did all learners achieve the LO?

If not, why?

Did my planned differentiation work well?

Did I stick to timings?

What changes did I make from my plan and why?

Use the space below to reflect on your lesson. Answer the most relevant questions from the box on the left about your lesson.
