The Science Technology Engineering and Mathematics (STEM) Trek is a hike around the Mall area of downtown Washington DC highlighting some of the STEM that was involved in the creation of Washington D.C., and showcasing the government agencies and private organizations involved in STEM that are located in Washington DC.    The Trek includes 24 stops; each has a question for you to answer (a cub scout level question, a Scout BSA level question and an on-site question). There is an ‘abbreviated’ trek highlighted in the guide for those who prefer that.  Follow the DC STEM Trek Guide!  Use the STEM Trek Blank Answer Sheet Watch as Girl Troop 1853 describes the STEM Trek
