  1. Daily warm-up • 1) It is 210 km from Dunedin to Invercargill. If Kauri drove at an average of 83 km/h, how long would it take him to get there? • 2) It took Anaru 53.2 seconds to run a 400m race. What was his average pace in m/s? • 3) Kaia swims at an average pace of 0.8 m/s. How far can she swim in 10 minutes?

  2. Daily warm-up answers • 1) Kauri: 2hr 32min • 2) Anaru: 7.52m/s • 3) Kaia: 480m

  3. PLAN FOR TODAYSPEED • Outside lab calculating the average speed of cars driving past the school • Dress for the weather • Represent your school • Street safety • We are only measuring speed, NOT rapid deceleration or collisions!!!

  4. Directions • Work in teams of 3 • Measure out a distance between 10m and 100m • Time how long it takes a car to cover that distance • You may use two different distances if you want to compare. • Measure the speed of at least 10 cars • 5 at each distance if you are using two distances • Note the colour of every car (red, blue, etc.) • Record all of your data in a table.

  5. Example Table • Calculate average speed in m/s and km/h • Come up with an overall average speed for all cars • Select two colours where you have the most cars and compare them to the average

  6. Compare Car Colours • Select two colours and compare them to the average • Represent this comparison in a chart • Present your findings to the class
