Do you have a ham radio operator close to you?
Send and recieve a signal up to a satellite and have a receiver
close by to receive said signal.   Use Vernier sound probe and
ULI to measure time between send and receive and then knowing the
distance to the satellite,  calculate the speed of "light".

Each year in the light and optics unit, there is at least one
student asked how the speed of light 3* 10^8 m/s is measured or
obtained.  For three years I tried to show the class, but ONLY
VERY FEW students can follow the presentation.  It became a
lost cause and a waste of time.  Does any one has any easy,
simpler way or method (less mathematical and easier to
understand)  to answer this question.
