Summer Data-science track at the Northrop Grumman STEM camp
Beginning in 2017, we're working with Northrop Grumman and Rangeview High School in Aurora to put on a week-long data science track for high school students as part of their overall STEM camp (other tracks include cyber-security and space). Our data science group included 14 students.
In 2018, we expanded the program to include St. Vrain School District. This continues inn 2019 and 2020 (in 2020, we are online-only; see here to register).
