This is a set of links for SAB videos explaining the NGSS standards to students (and teachers) . Some video links are followed by a link to a playposit that I assign to students to help them stay focused.
HS-PS4-3: Double Double Waves in Trouble: Two Source Interference (PlayPosit)
HS-PS4-3: Inside Einstein's Mind: Exploring the Photoelectric Effect (PlayPosit) (This video uses a Physics Classroom interactive linked here.)
