In Project Discovery Revisited: A Horse Training Center, several aspects of horses are explored. On a visit to the riding stables, horseback riding lessons are explained as well as how to train the horse to have a rider. Training a horse to pull a buggy is also explored. In another portion, students will follow a horse doctor on one of his regular visits where he explains what he does. The role of the farrier, or horse-shoer, is discussed, and students learn how shoes are made, used, and maintained. The job of a horse patrol policeman is also explored.
