A high school student teaches elementary students how to play a game on Unplugged Night.

Locust Valley Central School District, its principals and parent councils welcomed students and parents for its second annual Unplugged Night on March 10.

While students did arts and crafts, played games and socialized with members of the high school’s student government, parents learned cyber safety techniques and healthy habits to prepare their children for the modern digital environment from Yale University-trained clinical psychologist Dr. Marie Bragg.

Dr. Bragg, an assistant professor in the Department of Population Health at the NYU School of Medicine, showed parents how to utilize apps and services that limit social media use, and spoke about the techniques that companies use to market to children.
