The primary goal of the Exploratorium "Science At Home" project is to provide parents with activities that help foster a culture of learning in their homes. This study explores the impact of this program on family participation in science related activities, parental attitudes toward science, parental participation in science, and parental perceptions of their child's ability to do science and choose science as a career. A 50-item "gender questionnaire" was used to collect data. The demographics of the participants in the project support the theory that well-educated professional parents tend to create home environments that support scientific curiosity and nurture interest in science. Results indicate that it is possible for informal science education centers to create home-science activities that encourage active participation by both women and young girls. Other findings include: the project did not positively improve how women judge their own aptitude for learning science; participation in the project may have encouraged mothers to purchase more science toys for their children; fathers appeared to hold fewer gender biases than mothers when assessing a child's science interest and capabilities; and both mothers and fathers have more positive expectations for sons than daughters with regard to careers in science.
