I have just started the topic of Motion with my Year 9 students and used an obstacle course as an active way to introduce speed, distance and time equations.
The students set up an obstacle course in the sports hall (balance beams, hopscotch, cones, a wall to climb over etc.) Then, working in pairs, one member of each team tackled the course whilst the other timed them and recorded how long it took to complete each section. The students also recorded the length of each section using a measuring tape e.g. balance beam = 3m, hoops = 8m.
Now that the students knew the distance and the time taken, they could work out the speed at which they completed each obstacle. Finally, the students were asked to plot a distance-time graph (which lead nicely onto the follow-up lesson in which we looked at motion graphs using DynaKars).
