PERFORMANCE OBJECTIVES

  • By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor):
  1. devise ways to measure time;
  2. state the standard unit for measuring time;
  3. name the instrument for measuring time;
  4. use standard instruments to measure time;
  5. construct and use simple time devices.

 

 

INSTRUCTIONAL MATERIALS

  • The teacher will teach the lesson with the aid of:
  1. A chart showing some time measuring devices.
  2. A chart on the standard units for measuring time.
  3. Stop watches
  4. Empty bottles
  5. Water
  6. Shoes with laces,
  7. Plastic funnels and dry sieved sand

 

REFERENCE MATERIALS

  1. Scheme of Work
  2. 9 – Years Basic Education Curriculum
  3. MacMillan Basic School and Technology Book 4
  4. All Relevant Materials

 

 

CONTENT OF THE LESSON 

UNITS FOR MEASURING TIME 

We can measure time in:

  1. seconds
  2. minutes
  3. hours
  4. days
  5. weeks
  6. months
  7. years
  8. decades
  9. centuries
  10. millenia

 

  • Seconds – it is used for measuring a short length of time. Digital stopwatch or clock is the best and easiest equipment used for measuring seconds. It is very important to able to read analog.
  • Minutes – it is used for measuring time that is likely to be longer than 60 seconds. The best equipment for measuring minutes is stop clock or watch. Ordinary watches/clocks can be used but your measurements may not be accurate.
  • Hours – it is used for measuring a longer period of time usually a day or week. The best equipment for measuring hours is clock or watch.

 

INSTRUMENTS/MATERIALS FOR MEASURING TIME

Throughout history, various instruments/materials of increasing accuracy have been used to measure.

  1. Cock
  2. Table clock
  3. Wall clock
  4. Wrist watch
  5. Hourglass
  6. Candle sticks
  7. Pendulum clock
  8. Sundial
  9. Chronometer
  10. Sunlight

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

  1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;
  2. Guides pupils to sequence events by illustrating activities with series of pictures;
  3. Pupil’s Activities – Observe how long it takes to carry out certain activities. For examples: filling an empty bottle of water; fastening and loosening shoe laces; run from one end of the football field to the other, etc. Sequence events e.g. daily activities and life cycles.
  4. Uses pictures and charts to guide pupils to: identify time measuring devices; state the units of time (seconds, minutes and hours) with appropriate symbols;
  5. Pupil’s Activities – Construct and use simple measuring devices.
  6. Shows pupils how to use the shadow, water and pendulum clock, hour glass, etc. to measure time.
  7. Pupil’s Activities – Make and calibrate simple clocks.

 

CONCLUSION

  • To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

 

LESSON EVALUATION

  • Pupils to:
  1. devise ways to measure time;
  2. state the standard units for measuring time;
  3. name three instruments for measuring time;
  4. use standard instruments to measure time;
  5. construct and use simple time devices.
