Girls Ask Why is a Girl Scouts web-site that focuses on science projects. A special project of the site, Girls At the Center (G.A.C), encourages girls in hands-on science with the support of their families and other caring adults. Each G.A.C site has a science and technology museum to work with, and a national advisory board gives guidance to the project.
