Get the bee movie that recently came out with J Sienfeld. You can easily see that some bees hang out in coffee shops, some attend the latest court cases, and some girl bees drool over pollen jocks all day long.... :-D
Ok, just kidding of course.
How about starting with the life cycle poster sold at most bee supply places. It depicts the different jobs the bees go through within it's lifetime.
On a daily basis, when field bees are not foraging, etc., they are regulating hive temperature, resting, etc. Some bees are always tending the queen and others always feeding brood. But the daily work load is dependant on the age of the bee and the role it fills that particular day.
You can see alot from an observation hive. And when the sun goes down, many bees are really doing little and go off and seem to rest. The brood area remains active, but this is for a smaller number of bees.
