Key Stage 1
Meaning
Time is how long something takes to happen. To time is to use a timer to find out how long something takes.
About Time
Time can be measured in seconds, minutes, hours, days, weeks, months and years.
Examples
- It takes 5 minutes to boil an egg.
- It takes 2 hours to drive from Birmingham to London.
- It takes 28 days for The Moon to go around the Earth.
Used in a Sentence
- A scientist decided to time how long it takes to boil an egg.
- A scientist drove to London from Birmingham and it took a time of 2 hours.
- A scientist noticed the full moon and predicted the next full moon would be in 28 days time.
Key Stage 2
Meaning
Time is a measure of how long something takes from the start to the end of something happening.
About Time
- Time can be measured in seconds, minutes, hours, days, weeks, months and years.
- Time can be measured using a clock or a stopwatch or a timer.
Key Stage 3
Meaning
Time is a measure of how long something takes from the start to the end of something happening.
About Time
Time can be measured in:
- Seconds - Used for quick events like the rate of a reaction.
- Minutes - For slow reactions or journeys of a few miles.
- Hours - For long journeys or slow changes in organisms.
- Days - For gradual changes in organisms.
- Weeks - For changes in a humans mass or height.
- Months - A variable length of time from 28 to 31 days, avoided in science.
- Years - For the orbits of other planets around stars.
Key Stage 4
Meaning
Time is the measure of the duration of an event.
About Time
Time can be measured in:
- Nanoseconds - One billionth of a second, an ultra fast LASER pulse.
- Microseconds - One millionth of a second, the time period of an ultrasound wave.
- Milliseconds - One thousandth of a second, the response rate of a tv screen.
- Seconds - For quick events like the rate of a reaction.
- Minutes - For slow reactions or journeys of a few miles.
- Hours - For long journeys or slow changes in organisms.
- Days - For gradual changes in organisms.
- Weeks - For changes in a humans mass or height.
- Months - A variable length of time from 28 to 31 days, avoided in science.
- Years - For the orbits of other planets around stars.
