STEM Education Defined What would make you most interested in becoming a National Park ranger? Reading about forests, attending a lecture on what a park ranger does, watching a video called 'A Day in the Life of a Park Ranger' or frequently hiking through national forests?
Rugby Sevens redirects here. For the rugby league derivative, see Rugby league sevens. Rugby sevens, also known as seven-a-side, Sevens or VIIs, is a variant of rugby union in which teams are made up of seven players, instead of the usual 15, with shorter matches.
There are several variations in laws which apply to Rugby sevens, primarily to speed up the game and to account for the reduced number of players. The main changes can be summarised as follows: 1  7 players per team on field (instead of 15). 2  Five substitutes, with five interchanges (instead of 7 and 7).
