Explore the movement of light and sound from a lightning strike during a thunderstorm. Measure the time delay between seeing a lightning flash and hearing the sound of thunder. Use the time difference and speed of sound to estimate the distance to the lightning strike. For example, if thunder is heard six seconds after seeing lightning, then the lightning strike must be about two kilometers away. This learning object is one in a series of four objects.
Objective
