E: CONTENT
Revision of Measurement
Length tells us how long or short an object is. Examples of instruments used to measure length are:
- Ruler.
- Metre rule.
- Measuring tape.
Mass tells us how heavy or light an object is. It can be measured using:
- Weighing scale.
- Weighing balance.
Time tells us when an event happens or how long an activity takes. It can be measured using:
- Clock.
- Wristwatch.
Revision of Light
Light helps us to see. Natural sources of light include:
- ☀️ Sun
- ⭐ Stars
- ⚡ Lightning
Artificial sources include:
- 💡 Electric bulb
- 🔦 Torchlight
- 🕯️ Candle
Revision of Mirrors
A mirror is a smooth surface that reflects light. An image is the picture seen in a mirror. Reflection is the bouncing back of light from a surface.
Revision of Technology
Traditional technology uses simple tools. Examples:
- Hoe.
- Cutlass.
- Mortar and pestle.
Modern technology uses improved machines and devices. Examples:
- Tractor.
- Computer.
- Mobile phone.
- Aeroplane.
F: LESSON PRESENTATION
F1: Teachers’ Activities
- Revises measurement with the pupils.
- Displays measuring instruments.
- Revises sources and uses of light.
- Demonstrates reflection with a mirror.
- Shows pictures of traditional and modern tools.
- Asks pupils revision questions.
F2: Pupils’ Activities
- Identify measuring instruments.
- State units of measurement.
- Mention sources of light.
- Observe reflection in a mirror.
- Identify traditional and modern technology.
- Answer revision questions.
G: CONCLUSION
The teacher revises the major topics taught during the first term and corrects pupils where necessary. The teacher encourages pupils to remember previous lessons as they begin the new term.
