A lot or a little?
The parents' guide to what's in this website.
What parents need to know
Parents need to know that this site -- a project of the Girls, Math & Science Partnership -- provides excellent resources for girls who are interested in science, and encourages them to use their skills to make the world a better place. The only aspect of the site that might give parents pause is registration, which asks users to provide a lot of information, including home address and phone number. (Most of site's features can be accessed without registration, though.)
Is it any good?
The Girls, Math & Science Partnership aims "to engage, educate, and embrace girls as architects of change" -- a mission that's carried out colorfully on BRAINCAKE. The site rounds up helpful resources and links to lots of other sites, from educational games to information on careers, homework help, and science news. Original content on BrainCake includes interviews with notable girls and women in science, an engaging collection of teen-hosted podcasts called GirlTalk Radio, and an excellent mentor-match program. The site does a good job presenting science and math as vibrant, relevant pursuits, rather than subjects to struggle with in school.
