Week 6                                                          Lesson

Date:

Class: G. G 4

Time:                                                             Period(s):

Duration: 35 minutes

Subject: BASIC SCIENCE AND TECHNOLOGY

Topic: BASIC ELECTRICITY

Sub-topic:

Instructional material/teaching aids: A chart showing diagram of an electrolytic system

Specific objective(s): At the end of the lesson the pupils should be able to

(a) Define electricity

(b) Explain the types of electricity

(c) State the methods of generating electricity

Previous knowledge: The pupils have been

Introduction: The teacher introduces the lesson by a

Presentation: The teacher presents the lesson in the following steps thus:

Step i: Electricity also known as electrical energy is defined as a form of energy generated by the flow of free electrons

Step ii: Types of electricity

  1. Static electricity: This is generated when free electrons gather at a position. Static electricity causes an attraction between a plastic pen and piece of papers
  2. Current electricity: This type of electricity is generated when free electrons move or flow in chemical substances and metals. This is the most useful type of electricity and it is used to operate electrical and electronics appliances. A lighted bulb is due to current electricity generated as the electrons flows in the metal wire connected to a dry cell

Step iii: Methods of generating electricity

  1. Friction Method: This method involves wrapping fur or cotton wool around a hard rubber rod and the rubber rod is made to slide to and fro. This process makes the rubber rod to be negatively charged while the fur is positively charged. If wire were to be connected from the fur and rod to the terminals of a galvanometer, there will be a deflection showing the presence of electricity in the system. The quantity/amount of electricity depends on the speed of the sliding rod
  2. Magnetic method: This method requires the use of small coil of wire, a bar of magnet, an iron bar and a galvanometer. The ends of the coil wires are connected to the terminals. As the bar magnet is inserted into the coil wire, the galvanometer detects the presence of electric current. The quantity of electricity depends on the number of turns of the wire and the strength of the magnet
  3. Chemical method: this method converts chemical energy into electrical energy. This system is made up of an electrolyte (common salt and water), two different plates (zinc and carbon rod), wire, lamp holder with bulb and a container

Evaluation: The teacher evaluates the lesson by asking the following questions thus:

(a) Define electricity

(b) Explain the types of electricity

(c) State the methods of generating electricity

Conclusion: The teacher concludes the lesson by summarizing the main points of the lesson thus: Electricity also known as electrical energy is defined as a form of energy generated by the flow of free electrons

Assignment:

Assignment1. Define electricity

  1. Distinguish between static and current electricity
  2. List the methods that can be used to generate electricity
  3. Explain the chemical method with the aid of a diagram
