Activities are the individual units of delivery for each module. A single module is typically delivered as a combination of many activities. Each unique combination of day, time and resources constitutes an activity. Repetition across many weeks is considered as a single activity with a repeating week pattern.
For example, the lecture for the module Design for Function occurs on Monday at 10am, during every week of the first semester. It is taught by the same lecturer each week, in the same room, and is attended by the same students. This constitutes a single activity.
