REACT
Research Education and Activities for Community Teachers is a two-day workshop hosted at Cornell for K-12 teachers in New York State in which grad students develop lessons and activities based on their research to share with teachers. You can find a session on Electricity and Physics I led and some of the educational resources I developed in the 2021 archive, and a video recording of a talk in the 2020 archive.
GRASSHOPR
The GRAduate Student School Outreach PRogram at Cornell pairs graduate students with local K-12 classrooms. I was a GRASSHOPR fellow in 2019, and gave several lessons on imaging and cameras to a 12th grade physics class with hands-on activities.
