Instructor Drew Schwegman gives a few guitar tips to a group of Mercer County-area students during a Students Teaching About Resistance (STAR) weekend retreat program Sunday at the Spiritual Center of Maria Stein. The seventh- and eighth-grade students were able to choose from a variety of workshops including yoga, make-up application and jewelry making. During the two-day retreat, the students also learned about drug and alcohol prevention by attending a variety of personal growth sessions on leadership and self-esteem.
