Make a List
What departments and roles are you interested in learning about? Make a list of the people you want to talk to and think about what you'd like to learn from the conversation.
Follow the Communication Norm
Does your organization communicate mostly via email? Phone? Is it normal for people to stop by someone's desk to ask them a question? Pay attention to how the people around you work and interact and follow their lead when it comes to approaching your coworkers. Then, use that method to respectfully approach the people you want to meet with. Introduce yourself, tell them what department you are interning in, tell them your major and where you go to school, and tell them you're interested in learning more about what they do. Then ask if you could set up a time to talk. Be gracious and don't act like anyone owes you anything -- they don't.
People are busy, so if they've taken the time to sit and talk with you make sure you come prepared. Do some background research on their department's recent successes, this person's role in the company, and take a look at the LinkedIn to get a sense of their background. Prepare a few questions and think about what you want to take away from the meeting.
Be sure to thank the person within 24 hours. If they've offered you some sort of advice -- like a book to read or someone else to talk to -- make sure you follow up on that action and let them know how helpful it was (even if it wasn't that helpful).
