From W3C Wiki
The Activity schema is proposed as a way to separate a general real world activity from other schemas such as events, places, touristattractions etc.
A general activity may be anything from 'take a walk in the park' to 'learn to draw', 'swim in the ocean' or 'play poker'.
Activities to do (for example when planning a party or a team building event) are commonly searched for on the web. An activity schema would help people more easily identify, filter and browse activities.
It would also help search engine users differentiate between football as an activity, a football match (event), a football club (organization) or the object football (product).
The Schema will help people who are looking for new things to do (E.g. at will, regularly or once in a lifetime).
The Schema is important because of the growing obesity epidemic. We need to help people get more physically active.
