Note to Pupils:
TIME:
Time is when we measure when events happen.
Time helps us know when things happen, like when we wake up, go to school, and have fun.
Olden Methods of telling time included things like:
- Watching the position of the sun in the sky.
- Listening to the crow of the cock (rooster) in the morning.
- Observing the shadows cast by objects.
- Using hourglasses that let sand flow from one part to another.
- Lighting candles or oil lamps with markings to track time.
Modern Methods to tell time are:
- Wall Clocks: These are clocks we hang on walls at home or school.
- Wristwatches: You wear them on your wrist like a bracelet.
- Stopwatches: They are used to measure short periods, like in sports or races.
- Digital Clocks: These show numbers to tell us the time, often found on phones and computers.
- Alarm Clocks: They can wake us up at a specific time with a loud sound or music.
