sit somewhere where there is tile, set a small rock in front of you. make a chi ball and imagine it split apart into strings attached to the rock and fingers. imagine the strings fill the rock with your chi substance, than wrap around the rock.. lift your hands about an inch, keep your hand there for a while. drop the rock and if you here a clatter you are officialy an earthbender. practice this until you can do it without thinking about it.
put your hand on the ground or your feet on the ground. radiate you chi into a circle around you. have someone drop a rock within the chi circle. try to feel the vibrations from the rock. walk towards the rock. once you think you are at the rock open your eyes and if your at the rock than you have completed this lesson. after you can do it with a rock try it with people walking around.
