You have been duped. By whom, I'm not sure. Is it your child telling you that nothing is going on at BCC? Maybe he/she doesn't want to participate or is having trouble making friends.
BCC offers zillions of sports, music, theater, after school clubs, etc.
Check this link for current activities at BCC --
http://www.montgomeryschoolsmd.org/schools/bcchs/activities/ It is the activities tab on the main web school web page.
If you click on publications you will see that there is a yearbook, literary magazine and newspaper. The newspaper -- The Tattler -- is the oldest in the country, and has won awards from Columbia/Journalism, but you may have to sign up for Journalism class to fully participate. The online Tattler Extra is here --
http://tattlerextra.org/ -- and appears to have a number of current stories.
The literary magazine, Silver Chips, has also won many prestigious awards. I know that many BCC alum who are now professional writers credit the old sponsor, Ms. Lambrakopoulos, and the Silver Chips experience with helping their writing. (See the section on Chevalier in

On the clubs page you will see every club under the sun including debate, math teams, language and honors clubs, etc. It's clear from the list and the info. that if you don't find the club you want, you can create it. I don't know what it means that the clubs list still has the heading 2009-2010, but it's hard for me to imagine that all these clubs have simply disappeared in 1 year unless there's some kind of budget issue.
There are also many theater and music opportunities.
Anyway, if you can't find it at BCC, why don't you start it? One of the great things about attending a large school -- you will find at least a small group of people who are interested in the same things you are. If science club doesn't exist and your child wants to have one, no one will tell him/her it's not allowed. Find a faculty or parent sponsor, put up some posters and I'm sure a few kids will crawl out of the woodwork, or should it come to it, that a faculty member would work solo with a student with a particular interest.
