Video Tutorials & Recorded Seminars


I frequently do guest lectures, seminars, public talks, participate in panels, career days, etc. We also do demos of chemical gardens for visitors or classes and/or can advise on setting one up for your event. Email me (lmb at lauriebarge dot com) for more information.

I am a science / career mentor to typically 4-5 students per year. Over the years I have had students from various LA-area community colleges and public universities as well as out of state institutions. I have mentored students through various JPL/NASA student research programs, community college intern programs, and through the Blue Marble Space Institute of Science Young Scientist Program (in which students complete science communication and ethics modules in addition to their research). 


Outreach Projects

Bridge to the Geosciences

Marianne Smith (PI), Laurie Barge (Co-PI), Valerie Sloan (Co-PI)


Bridge to the Geosciences is a three-year project funded by the National Science Foundation awarded in 2015, designed to provide students from Citrus College (a Hispanic-serving two-year public community college in LA county) an opportunity to explore the possibilities the geosciences hold for all STEM majors. Over the course of a year, each Bridge to the Geosciences cohort will participate in four distinct experiences or "geomodules" organized around different subfields of the geosciences including the planetary, atmospheric, ocean and environmental sciences. In Year 1, the geomodules included a day at the Oak Crest Institute of Science, a day at the NASA Jet Propulsion Laboratory, a weekend at the USC Wrigley Center on Catalina Island, and a 10-day "mini-internship" at the University Corporation for Atmospheric Research (UCAR) in Boulder, CO. The program also includes a focus on mentoring, education and career advice, community-building and networking.
