From homemade bath bombs to toothbrush-and-rubber-band robots, the Do It Yourself Science collection from Carnegie STEM Girls has over three dozen at-home experiments for aspiring scientists. The experiments show that "you can demonstrate cool scientific principles and test out your ideas with everyday objects found all around you." Each experiment is accompanied by a materials list and set of instructions, and most also feature additional content. For example, the "Edible DNA" experiment links to information on related careers in biology and neurobiology, while the "Scribble Bots" experiment includes a couple of electricity-themed fun facts. A project of the Duquesne Light Co. Center for STEM Education and Career Development, Carnegie STEM Girls aims to help "girls recognize that STEM topics and careers are pretty cool." In addition to the resources highlighted, the site hosts other tools for students, parents, and teachers including She's Livin' It!, which profiles women in STEM careers, and Careers A-Z, which provides information on many STEM and STEM-adjacent career paths.
