Give an example of a device that you use that is affected by relativistic effects. How do you resolve the twin paradox? Apart from the space-time interval, s, what else is Lorentz invariant? Look up a video illustrating the barn paradox, and other relativistic effects. Propose an experiment to measure the speed of light.
