C: PREVIOUS KNOWLEDGE
The pupils have learnt about changes in nature, plants and animals, weather, colours and different types of measurement during the first term.
D: PERFORMANCE OBJECTIVES
By the end of the lesson, pupils should be able to:
- Explain temporary and permanent changes.
- Mention changes in plants and animals.
- Identify weather elements and instruments.
- Name primary and secondary colours.
- Identify instruments used for measuring length, liquids and solids.
- State common units of time.
E: CONTENT
Revision of Temporary and Permanent Changes
A temporary change can be reversed. Examples:
- melting ice
- folding paper
- stretching rubber
A permanent change cannot easily be reversed. Examples:
- burning wood
- rusting iron
- cooking food
Revision of Changes in Plants and Animals
Plants change as they grow. 🌱 Seed → Seedling → Mature Plant → Flower → Fruit Animals also change as they grow. Example: 🐣 Chick → Chicken
Revision of Weather
Weather is the condition of the atmosphere at a particular place and time. Weather elements include:
- sunshine
- rainfall
- wind
- temperature
- clouds
Weather instruments include:
- thermometer
- rain gauge
- wind vane
- barometer
Revision of Colours
Primary colours are:
- red
- blue
- yellow
Secondary colours are formed by mixing primary colours. Examples:
- red + yellow = orange
- blue + yellow = green
- red + blue = purple
Revision of Measurement
Length can be measured with:
- ruler
- metre rule
- measuring tape
Liquids may be measured in:
- millilitres
- centilitres
- litres
Time can be measured in:
- seconds
- minutes
- hours
- days
- weeks
- months
- years
