Main Body of Lesson
- What is speed? Try to get across the concept of rate of distance travelled
- What is the unit – lots will say 1 mph. Ask the pupil to walk around the class at 1 mph (0.45m/s) or 1kmh (0.28m/s)
- Think about how long it would take an Olympic sprinter to cross the room (pace out room for a rough distance)
- How do we measure speed? Give out some stop clocks and get pupils to measure the speed of a “RC car?” around the room. Have 5 people measure and take a mean. Discuss why we take a mean.
- Try to use a car through a light gate? Compare with the value the class got?
- Do some speed calcs (featuring multiples and sub multiples)
