SciGirls has the bold goal of changing how millions of girls think about science, technology, engineering and math - or STEM. Each half-hour episode highlights the processes of science and engineering, following a different group of middle school girls who design, with the help of scientist mentors, their own inquiry-based investigations on a variety of topics. They also learn how rewarding and fun it is to work with their peers, and the shows' female mentors offer girls a glimpse of exciting STEM career possibilities. SciGirls educational materials provide gender-equitable teaching strategies and hands-on inquiries based on the concepts modeled in SciGirls' videos. Included in this collection: Video (240), Document (59) for Grades 3-5, 6-8, 9-12 , Resources in Spanish (276).
