My DD's school doesn't have an engineering club, but engineering activities are part of the math enrichment program. They are always very popular as is the engineering day the students travel to a nearby university to attend. In attendance, these programs are split pretty evenly between boys and girls.
Her school doesn't have quiz bowl at the middle school level. The students started up the chess club again last year, but it's very small and only had boys involved last year.
The math enrichment program which includes math competitions is the most popular program with an academic bent; robotics club is also very popular though boy heavy.
