Shawn will go back to school where he meets a teacher who has put a new spin on teaching STEM classes. He really makes learning fun and relevant! Those audio and sound systems you see in churches, concert halls and corporations aren't one-size fits all. Helena talks with a systems analyst who gives her some insight into how he advises his clients on their A/V needs. Rehabilitation after surgery or a medical condition is very important to a person's successful recovery. Shawn will meet up with a physical therapist assistant and learn how she works with her patients to restore their physical function.
