INSTRUCTIONAL PROCEDURES

PERIOD 1: Measurement of time

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1INTRODUCTION The pupils are asked to mention and demonstrate the ways in which they measure time in their localities The class uses the data collated from the pupils to formulate the meaning of time- Time is the measured or measurable period during which an action, process, or condition exists or continues Pupils pay attention STEP 2EXPLANATION The teacher explains that there are two types of measurement for time and gives examples of each1. Olden methods e.g. sandglass, pendulum, quartz, pendulum, candle clock etc 2. Standard methods- sundials, water clocks, digital clocks, wristwatches etc Pupils pay attention and participates STEP 3DEMONSTRATION She further explains and demonstrates the metric unit of time60 seconds = 1 minute60 minutes = 1 hour24 hours = 1 day7 days = 1 week4 weeks = 1 month12 months = 1 year52 weeks = 1 year365 days = 1 year366 days = 1 leap year(which happens every four years) Pupils pay attention and participate STEP 4NOTE TAKING The teacher writes a short note on the board The pupils copy the note in their books

NOTE

Time is the measured or measurable period during which an action, process, or condition exists or continues

There are two methods for measuring time

1. Olden methods e.g. sandglass, pendulum, quartz, pendulum, candle clock etc
2. Standard methods- sundials, water clocks, digital clocks, wristwatches etc

Metric unit of time

60 seconds = 1 minute

60 minutes = 1 hour

24 hours = 1 day

7 days = 1 week

4 weeks = 1 month

12 months = 1 year

52 weeks = 1 year

365 days = 1 year

366 days = 1 leap year (which happens every four years)

EVALUATION:    1. Define “Time”

1. Describe two olden methods and two standard methods of measuring time
2. Recite the metric unit of time

CLASS ACTIVITY: Pupils are placed in small groups, and asked to discuss how specified tasks are done within a particular timeframe.

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively

PERIOD 2 and 3: System unit. Physical fitness

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1INTRODUCTION The teacher revisits the previous lesson and introduces the new topic by explaining what System unit is- System unit is the part of a computer that houses the primary devices that perform operations and produce results for complex calculations Pupils pay attention STEP 2EXPLANATION The teacher using the chart, enumerates the different parts of the system and describes their functions1. Motherboard. It connects all computer nodes into one device. It is a set of wires between the processor contacts and the contacts of memory modules and peripheral devices.2. Processor- it is the brain of the computer and performs the bulk of the computer’s work. Data from other parts of the computer is sent to the processor for calculations.3. RAM- It means Random Access Memory. It stores and makes it easy to quickly access data. All information on it is lost after the power is turned off.    4. Hard Drive- It is designed to store music, videos, photos, documents, and other files in the computer’s permanent memory.   5. Video Card- It converts the image in the computer’s memory into a video signal for the monitor.6. Power Supply- It provides power to the Computer. Pupils pay attention and participates STEP 3DEMONSTRATION She further explains what physical fitness is- Physical fitness is the ability of the body to function both effectively and efficiently when performing physical activity without becoming exhausted too quickly. She then demonstrates the components of physical fitness using various activities1. Agility: It is defined as the ability to move with speed and ease. Activities that build agility are lateral running, jump box drills etc2. Endurance: It is the ability to put up with strain, suffering, or hardship. Activities that build endurance are long hike, walking briskly, biking, jumping rope etc3. Strength: It is how strong one is. Activities that build strength are weight lifting, cycling, push-ups, sit ups etc4. Flexibility: It is the ability to move the joints freely. Activities that build flexibility are yoga, pilates, stretching etc Pupils pay attention and participate STEP 4NOTE TAKING The teacher writes a short note on the board The pupils copy the note in their books

NOTE

System unit is the part of a computer that houses the primary devices that

perform operations and produce results for complex calculations

Different parts of the system and their functions

1. Motherboard. It connects all computer nodes into one device. It is a set of wires between the processor contacts and the contacts of memory modules and peripheral devices.
2. Processor- it is the brain of the computer and performs the bulk of the computer’s work. Data from other parts of the computer is sent to the processor for calculations.
3. RAM- It means Random Access Memory. It stores and makes it easy to quickly access data. All information on it is lost after the power is turned off.
4. Hard Drive- It is designed to store music, videos, photos, documents, and other files in the computer’s permanent memory.
5. Video Card- It converts the image in the computer’s memory into a video signal for the monitor.
6. Power Supply- It provides power to the Computer.

Physical fitness and its components

Physical fitness is the ability of the body to function both effectively and efficiently when performing physical activity without becoming exhausted too quickly.

Components of physical fitness

1. Agility: It is defined as the ability to move with speed and ease. Activities that build agility are lateral running, jump box drills etc
2. Endurance: It is the ability to put up with strain, suffering, or hardship. Activities that build endurance are long hike, walking briskly, biking, jumping rope etc
3. Strength: It is how strong one is. Activities that build strength are weight lifting, cycling, push-ups, sit ups etc
4. Flexibility: It is the ability to move the joints freely. Activities that build flexibility are yoga, pilates, stretching, etc.
