A person is shown spinning around on a playground ‘carousel’ before getting off and walking away. The task is to graph the distance of the person from the centre of the carousel against time. Whilst the person is spinning on the carousel the resulting graph shows that distance is constant. This story can be used as...

A person is shown exercising using weights whilst lying on a bench.  As the weight is lifted the arms of the person curl around, so that the distance from the bench is not linear with time. As the exercise progresses it takes longer to do each bench press. Finally the weights are placed back on the resting stand....

A person is shown spinning around on a playground ‘carousel’ before getting off and walking away. The task is to graph the distance of the person from the camera against time. The resulting graph has periodicity and non-linear elements. This story can be used as a complement to ‘Distance from centre of carousel’...

A player is shown on a baseball pitch. They run around the bases before returning to the home plate. The speed varies between the different bases. The task is to draw a graph of the player’s distance from the home plate against time. The graph shows linear piecewise sections.

A paper plane is thrown from the balcony of a house. The plane initially gains height before curving as it falls to the ground. The challenge is to graph the elevation of the plane against time. The resulting graph is non-linear.
