“PhET provides fun, free, interactive, research-based science and mathematics simulations. We extensively test and evaluate each simulation to ensure educational effectiveness. These tests include student interviews and observation of simulation use in classrooms. The simulations are written in HTML5 (with some legacy simulations in Java or Flash), and can be run online or downloaded to your computer. All simulations are open source (see our source code). Multiple sponsors support the PhET project, enabling these resources to be free to all students and teachers.“ —PhET About page

(Shouldn’t every single day be Science Friday? Science Friday Monday, Science Friday Tuesday, etc.) “Science Friday is an award-winning producer of high quality, fact-checked, and trustworthy science news and educational programming. For 30 years, we’ve introduced top scientists to public radio listeners, and reminded them how much fun it is to learn something new. But we’re more than just a radio show. We produce a sweeping array of educational and entertaining science experiences through videos, podcasts, digital media, live events, citizen science, K-12 education and professional development, and at-home learning activities for families that directly serve hundreds of thousands of educators, parents, citizen scientists, and lifelong learners every year.” —ScienceFriday.com About page

This guide gathers select print and electronic resources for educators, parents, researchers, and young women on how to get girls (particularly middle and high school aged) interested in science and scientific careers.
