Learning Objectives

• Describe experimental proofs and show examples of Molecular-Kinetic Theory.

Lesson Objectives:

By the end of the lesson, the learner will be able to:

• ALL learners will be able to recall Molecular-Kinetic Theory.
• MOST learners will be able to describe the diffusion
• SOME learners will be able to explain the diffusion

Planned Activities

I. Organization moment:

Greeting

Announcing the topic and purpose of the lesson

• You will be able to recall Molecular-Kinetic Theory.
• You will be able to describe the diffusion
• You will be able to explain the diffusion

Asks the learners to complete the subject-specific vocabulary and terminology table.

II.  Introduction of new topic:

-Reviews previously learned concepts and check for preconceptions about the lesson content by asking question:

• What do you know about atoms and molecules?

Students answer the question;

Do you know that things:

• All matter consist of small particles (atoms and molecules)
• The particles are in ceaseless irregular motion
• The particles interact with each other?

Let’s read and translate together.

• Барлық заттар шағын бөлшектерден тұрады (атомдар мен молекулалар)
•  Бөлшектер әрдайым  қозғалыста
•  Бөлшектер бір-бірімен өзара әрекеттеседі

This is Molecular-Kinetic Theory. Please write down in the notebook this definitions.

How we can prove that molecules always move?

Give examples of diffusion from everyday life

• a tea bag in a glass of hot water
• sugar in a glass of tea
• sprinkle perfume
