INSTRUCTIONAL PROCEDURES

PERIOD 1: Frictional force

NOTE

Frictional force

Frictional force refers to the force generated by two surfaces that contact and slide against each other

She then discusses the application of friction in our everyday lives

• Friction finds application when matchsticks are ignited.
• Motion of pistons in a cylinder is an application of friction.
• It is possible to write on books and board as there is friction between pen and the board.
• Friction is what holds your shoe to the ground
• Brushing the teeth to remove particles
• Ironing a shirt

Advantages and disadvantages of frictional force

Advantages

• Friction enables us to walk freely.
• It helps to support ladder against wall.
• It becomes possible to transfer one form of energy to another.
• Objects can be piled up without slipping.
• Breaks of vehicles work due to friction.
• It always resists the motion, so extra energy is required to overcome it.

Disadvantages

• It always resists the motion, so extra energy is required to overcome it.
• It causes wear and tear of machines.
• It decreases the life expectancy of moving parts of vehicles.

Since friction is very useful in some cases while harmful in some cases, friction is called a necessary evil.

EVALUATION:    1. Define the term ‘Frictional force’

2. List five application of frictional force in our daily lives
3. State two advantages and two disadvantages of frictional force

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively

PERIOD 2 and 3: Swimming. Scratch programming

NOTE

Meaning and basic skills in swimming

Swimming is the movement of the body in the water using the arms and legs to stay afloat

Basic skills in swimming

1. breaststroke
2. freestyle
3. Backstroke

EVALUATION:    1. Define swimming

2. Outline the skills in swimming

CLASS ACTIVITY I: Pupils in small groups demonstrate the skills involved in swimming

CLASS ACTIVITY II: Pupils as individuals, apply scratch programming to an activity of their choice

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively
