How Far Does it Move?

Age 11 to 14 Challenge Level:

Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects the distance it travels at each stage.

Decimal Time

Age 11 to 14 Challenge Level:

Use the clocks to investigate French decimal time in this problem. Can you see how this time system worked?

Up and Across

Age 11 to 14 Challenge Level:

Experiment with the interactivity of "rolling" regular polygons, and explore how the different positions of the red dot affects its vertical and horizontal movement at each stage.

Motion Sensor

Age 14 to 16 Challenge Level:

Looking at the graph - when was the person moving fastest? Slowest?

problem icon

Steady Free Fall

Age 14 to 16 Challenge Level:

Can you adjust the curve so the bead drops with near constant vertical velocity?

Symmetric Trace

Age 14 to 16 Challenge Level:

Points off a rolling wheel make traces. What makes those traces have symmetry?
