Tasks applicable from my academics, learned and got experiences in classes I had not taken yet. Engaging work environment, coworkers always willing to help. One was also able to choose their hours coming in and out, as long as it added up to the full amount by the end of the week.

Take advantage of the knowledge of the people around you, ask about their projects and what they are doing.
