In Spring 2016, Wendy Ibsen of CSEP deployed a new PhoSoc-Designed activity to family science nights at local middle schools. As part of the FUSE family science-nights, UCSB grad. students led 8th grader's families through fiber optics and how they are used to transmit all our internet, television and telephone data.
The activity culminates in a challenge in which the families have to make a "Jell-o Waveguide" that bends the light back 180°, tested with a red laser pointer and paper safety glasses!
