 I had my students observe someone's gait, looking at all the possible factors. Shoes, backpack, hands in pockets or holding phone or drink or swaying at ease; length of steps, etc... They did well at this, so I had them do the same with the body language of an interaction between two people, observed from a discrete distance.  The third assignment was to observe... anything at all. The fourth is chosen by the students. They came up with 3 ideas: observing traffic patterns, nature, or their own emotions. 

For some reason, my group likes this particular thing.  They have to speak aloud but they can prepare to say something meaningful.  It's a way of preparing them to read literature, in which concrete objects gain significance because of the way in which they are observed.
