NOTE

Materials used in measuring weight and time

Weight

1. Balances- digital scientific balances and beam balance
2. Scales- modern digital or spring scale
3. Measurement Transducer
4. Vibrating Tube Mass Sensor

Time

1. clocks
2. watches.
3. atomic clock.
4. Stop watches

Metric unit of weight and time

Weight

10 milligrammes = 1 decigramme

10 decigrammes = 1 centigramme

10 centigrammes = 1 gramme

1000 grammes = 1 kilogramme

1000 Kilogrammes= 1 tonne

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. List two materials each used in measuring weight and time

1. Outline the metric units of weight and time

CLASS ACIVITY: pupils in small groups, measure solids and time accurately in turns by using weighing scales, clock wrist watch etc and record their measurement accurately

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively

PERIOD 2 and 3: Nutrition. Coding

 PRESENTATION TEACHER’S ACTIVITY PUPIL’S ACTIVITY STEP 1INTRODUCTION The teacher revisits the previous lesson on Gymnastics Pupils pay attention STEP 2EXPLANATION She explains the meaning of nutritionNutrition is the taking in and use of food and other nourishing material by the body. She also discusses the importance of nutrition1     Reduce the risk of some diseases, including heart disease, diabetes, stroke, some cancers, and osteoporosis.2     Reduce high blood pressure.3     Lower high cholesterol.4     Improve your well-being.5     Improve your ability to fight off illness.6     Improve your ability to recover from illness or injury                                                                  She highlights some deficiency diseases1.   Scurvy: It is caused by a deficiency of vitamin C.2.   Rickets: It is caused by the deficiency of vitamin D.3.   Anaemia: It is caused by the deficiency of iron.4.   Goitre: It is caused by the deficiency of iodine5.   Marasmus: it is caused by the deficiency of carbohydrates6.   Kwashiorkor: It is caused by the deficiency of protein7.   Dehydration: It is caused by the deficiency of water Pupils pay attention and participates STEP 3DEMONSTRATION The teacher discusses the uses of coding1. to build websites2. to create mobile applications3. to build computer games4. to create computer softwares 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

NUTRITION

Nutrition is the taking in and use of food and other nourishing material by the body.

Importance of nutrition

• Reduce the risk of some diseases, including heart disease, diabetes, stroke, some cancers, and osteoporosis.
• Reduce high blood pressure.
• Lower high cholesterol.
• Improve your ability to fight off illness.
• Improve your ability to recover from illness or injury

Uses of coding

1. to build websites
2. to create mobile applications
3. to build computer games
4. to create computer softwares

EVALUATION:    1. Explain the meaning of nutrition

1. Discuss four importance of nutrition
2. List some common deficiency diseases
3. Explain three uses of coding

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the pupils positively
