Mark 1 m intervals on the floor of the lab with marking tape—about 6 m if possible.
Have at least two students time each metre interval.
Students are to time from when the ball starts rolling to when it passes their designated metre
mark.
Roll the ball so that it is moving at a fairly constant rate.
Record the times for each metre mark in a results table.
Graph distance versus time.
Use the graph to determine average speed and if the speed is constant.

Copy a map of the journey from the street directory and mark the streets with a highlighter.
Remember to copy the scale of the map to determine the distance travelled.
Measure the distance travelled.
Calculate the average speed of the journey.
Determine the displacement of the journey.

Mark out a 50 m running track using a trundle wheel or tape measure. Mark every 10 m with
witches’ hats.
Select both timers who will stand at each 10 m mark and runners.
Timers record times from the start of the race until the runner passes their designated 10 m
mark (use multiple timers at each 10 m mark if you have enough students in your class).
Record times for each 10 m mark in a results table.
Graph displacement versus time.
Use the graph to determine average speed and if the speed is constant.
Runners could complete a number of different trials, such as walking at a constant rate,
sprinting or jogging, or organise a race.
