Lesson Plan ~ Basic Technology 1st Term JS 3 (Week 3)

XPINO SCHOLARS

LESSON PLAN
WEEK : 3		TERM : 1		SESSION : 2017/2018
SUBJECT: BASIC TECHNOLOGY		TOPIC: MECHANICAL TRANSMISSION SYSTEM: MOTION IN ENGINEERING SYSTEMS (TYPES AND CONVERSION)
CLASS: JS3	DATE: 02/10/17 – 06/10/17		LESSON PERIOD:   1 – 2
Learning Objectives:  At the end of the lesson, the students should be able to: define  motion; list four types of motion; differentiate between reciprocating motion and linear motion; explain  how motion can be converted; Study Questions:  What is motion? What are the four types of motion? What is the difference between reciprocating motion and linear motion? How can you explain conversion of motion?			Key words: Motion Reciprocating motion Linear motion Conversion of motion Clutch
			Instructional materials: Scrap engines or mechanical components that contain levers, linkages, slides and slots; charts, films, etc.
			Previous learning: The students can differentiate the motion of a ceiling fan from that of a pendulum clock.
Learning Activities in steps: Step 1 – Lesson Introduction. Step 2 – Teacher states learning objectives – including study questions. Guide the students to define drive mechanism. Then, class discussion on motion. Make good use of instructional materials during the class discussions. Motion simply means movement. There are four basic types of motion in engineering. These are: 1.      Rotary motion is turning around in a circle, such as a wheel system. This is a kind of motion that takes place in a rotating form (360º or less). 2.      Linear motion is moving in a straight line, such as a paper trimmer. This motion could be horizontal or vertical. 3.      Reciprocating motion is moving backwards and forwards or up and down in a straight line, as in cutting with a saw. 4.      Oscillating motion is swinging from side to side, like a pendulum clock. Step 3 – The Teacher guides the students in a class discussion on conversion of motion. In producing machine appliances, it is commonly necessary to convert motion from one type to another. Conversion of rotary motion to linear motion is possible through the use of lever arms, linkages, cams, pins, clutches, threads and springs. Step 4 – Class activity: (Basic Tech for JSS3 pages 165 – 167) Step 5 – Give the students exercises Step 6 - Teacher summarizes and evaluates lesson.

CLASS: JS3	DATE:  02/10/17 – 06/10/17		LESSON PERIOD:   3
Learning Objectives:  At the end of the lesson, the students should be able to: describe a clutch; explain what happens when a clutch is disengaged; Study Questions:  What is a clutch? What happens when a clutch is disengaged?			Key words: Motion Reciprocating motion Linear motion Conversion of motion Clutch
			Instructional materials: Scrap engines or mechanical components that contain levers, linkages, slides and slots; charts, films, etc.
			Previous learning: The students can differentiate the motion of a ceiling fan from that of a pendulum clock.
Learning Activities in steps: Step 1 – Revision of last lesson. Step 2 – The Teacher guides the students in a class discussion on clutches. Make good use of instructional materials during the class discussions. Clutches are included in motor vehicles to facilitate the conversion of rotary motion of the engine to linear motion. Clutches do this through the use of friction force. When a car is to be moved, the clutch is pressed against the friction plate. The face of the clutch has a high coefficient of friction and a low rate of wear. The friction transfers engine power to the driving shaft through the clutch. When clutch is disengaged the engine power is not transmitted. However, when the clutch is in engaged position, engine power is transmitted. Step 3 – Class activity: (Basic Tech for JSS3 pages 165 – 167) Step 4 – Give the students exercises Step 5 – Teacher summarizes and evaluates lesson.
