Re: After School Clubs
Football, Netball, Basketball, Dance, English, ICT, Maths, Science, Chess and Art Clubs
You said you want ideas for activities? For these clubs, I'd recommend fundraising activities. Every club needs money, regardless. Competitions as someone suggested. Within the school, and have the clubs register for regional/district competitions. For Math, science, and other academic clubs, have students do tutoring, and give them points for it. They need x amount of points to retain membership.
In math club, in high school, we used to do Pi Day. Pi is 3.14blah blah blah. So on March 14 (3.14), we would hold a day of schoolwide competitions, and have prizes. Every student heard the challenges and questions over the school radio/intercom/tv, and had to turn in their answers. We had this huuuuuge jar of MNM's, and people had to pay a quarter or so to guess how many MNM's there were in the jar. The person with the closest guess got the entire jar. I think the darn thing was like half my height tall.
For the sports clubs, they can do community service projects, like have them visit rehab homes for the elderly or young children, or hospitals. So they can see what its like to NOT have a body that functions well. Plus, it gives them ideas for body-oriented careers they can take up, if sports doesn't work out for them in the future.
A homework help hotline. Set up and run by students.
A student council that deals with student issues, and represents the student body and works with administration to get students the things they need, and fight for rights.
Peer counseling/mentoring program - kids in the school mentoring other kids in the school.
Since the school is so multicultural, having culture clubs, which work with helping new foreign students with weak english adjust, having activities that teach students how to speak the different languages represented by students, have cultural festivals, etc.
School fairs set up by students, where the students sell items to the community - good fundraising.
school plays/entertainment/theatre
School tv - can run announcements for the school. Also a student-run radio station.
