Science Cafes are free, informal public events designed to give the public an opportunity to explore contemporary science issues with a practicing scientist or researcher. Citizen scientists are changing the way science gets done, and the Internet is changing the way citizen scientists can get involved with new projects and expand their skills. Darlene Cavalier is the founder of Scistarter, an online citizen science community that collaborates with scientists to tackle formal and informal research projects. She also founded Science Cheerleader, working with cheerleaders pursuing science and technology careers to promote involvement of citizens in science and science policy.
