- Pupils can confidently use the speed equation
- Pupils can convert between various speed units
1.3 recall and use the relationship between average speed, distance moved and time: average speed = distance moved / time taken
- What is speed? Try to get across the concept of rate of distance travelled
Main Body of Lesson
- 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.
- You can also spread people out through the room and then do different calculations of speeds
- Drive a car through a light gate? How does this compare with the value the class got? Why are they different?
- Do some speed calcs (featuring multiples and sub multiples)
- I have a spreadsheet with land speed, air speed and motorbike speed records in. I don't know what it could be useful for though (AGR).
- Sheet featuring a series of speed calculations. Sheet in shared folder.
- Read page 26-27 and answer questions on page 27
- tray of stop clocks
- remote controlled car
- ball (to be passed around the room)
- long tape measure
- light gate and a method of mounting a picket fence onto the RC car
