To do this, it is probably good to have some serious preparation for the youth in your group.  Many times if you have an abortion clinic near you, there will also be groups of people who do this regularly.  So instead of just going and doing it, have one of these people come speak to your group, give them some training, and then bring them with them.  This idea of more about the experience the “feeling” of going and doing this than actually doing it while they are in high school.
