- Explain how to use rulers and measuring cylinders to measure length or volume accurately.
- Explain the methods for measuring different time intervals using both analog clocks and digital timers.
- Calculate the average for a small distance and a short time interval by measuring multiple instances, such as the oscillation period of a pendulum.
- Recognize that scalar quantities only have size, while vector quantities have both size and direction.
