The topic of the lessons

Electrical Charges (Электр заряд)

Learning Objectives

• Characterize electric charge;

• Give examples of positive and negative effects of charging

• Explain charging by rubbing, induction and contact.

Language Objectives:

Subject Learning:

Learners can characterize electric charge

Language Learning:

• Learners can interpret sketch graphs to explain force between charges (speaking and listening skills OR reading and writing skills)

Subject-Specific Vocabulary and Terminology:

neutral atom, electron, positive ion , electrical charges, positive charge, negative charge

Useful Sets of Phrases for Dialogue and Writing:

• Positive charge - every proton has a single positive charge.

• Negative charge - every electron has a single negative charge

• The charges can attract [pull] and repel [push] each other.

Previous learning

Fundamental building blocks of the matter are atoms.

Neutral atom – electron = Positive ion

Neutral atom + electron = negative ion.

II. Introduction new topic:

Electrical Charges

• Electrostatics is the study of electric charge at rest.

• Electric charge is a fundamental property of matter.

• Two types of electric charges

• Positive charge - every proton has a single positive charge.

• Negative charge - every electron has a single negative charge.

Note that the electron and proton both have the same charge, with the electron being negative and the proton being positive. This amount of charge is often called the

electronic charge, e. This electronic charge is generally considered a positive value (just like g in gravity). We add the negative sign when we need to:

q_e = -e; q_p = +e.

The charges can attract [pull] and repel [push] each other. Like [same] charges repel each other. Unlike [not same] charges attract each other.

Two different kinds of charge, positive and negative.

Electricity, with attractive and repulsive forces, needs two kinds of charge.

• Electric charge is measured in coulombs (C)

Properties of electric charge

1.Two kinds of charges occur in nature,

• like charges repel one another,

• and unlike charges attract one another.

2. Charge is conserved.

3. Charge is quantized.

• An object becomes electrostatically charged by:

  1. Friction,which transfers electrons between two objects in contact,

1. Contact with a charged body which results in the transfer of electrons,

2. Induction which produces a charge redistribution of electrons in a material.

III. Home task: Give examples of positive and negative effects of charging

Reflection:
