The K-12 channel will feature experts from across the Earth Institute presenting relevant sustainability content in 60-minute live sessions for K12 students and educators. Through these videos, we hope to bring our interdisciplinary research across our centers to classrooms. Each session will have an appropriate targeted age range based on the topic, and the sessions will vary between topical lectures, demos, and skills-based training. In addition to the videos, and whenever possible, we will offer additional educational resources related to the content covered in these online sessions.
