The idea is to record a backing track or loop with just a C chord being played. Could be just a simple 4 strums per bar but just the one chord. Then while that is playing, experiment with the C Major scale and see which notes sound the best. Does that make it clearer ?
If you had someone to play with they could play the chord while you play the scale.
Or maybe try playing over this C chord vamp. Just one chord for a whole 20 minutes, that should keep you busy.
Enjoy
