This year Massachusetts STEM Week will be October 18-22. See the schedule of virtual and in-person events across the state. Several organizations have contributed free Design Challenges for students and educators to explore. This year’s theme is “See Yourself in STEM,” focusing on mentoring women, people of color, first-generation students, low-income individuals, English language learners, and people with disabilities — all of which are underrepresented in STEM fields.
