Staying connected When Central Bucks South became one of the first Philadelphia-area high schools to close because of the fear of novel coronavirus exposure in early March，16-year-old sophomore Andrew Chen knew that things were not going to return to normal as quickly as some of his peers hoped.
   But still，the change from seeing his friends on the swim team during daily practices to learning alone at home was jarring.
   "I only have three years here at South，and it pains me to see one of them being wasted， " Chen said.
   The coronavirus has changed everyone's lives，but for students，the disruption feels particularly serious.Schools closed and graduation ceremonies were put off.Summer plans，such as camps，are up in the air.
   But right now，many students are trying to stay connected，struggling with false information，and finding out the best ways they can help—through online method.
   For Josh Harycki，17，a senior student at the Shipley School in Philadelphia，the best way to help was to create a "social distancing promise" for young people.
   "I saw a lot of young people not paying attention，" he said. "They were...still going out，hanging out with others.I thought that there had to be a way to reach younger people，who were possibly not watching the news. "
   Harycki started a call to action on social media and then built a website with a map that followed and kept the locations of people who'd signed the promise.The site also shares links to accurate sources of information like the US Centers for Disease Control and Prevention.
   Harycki knows that his peers are worried they can't connect with their friends in the same way so he created the social distancing promise to strengthen that although everyone might be physically distant，they're still connected.
   "Part of what we're showing is that you might feel like you're the only one taking this seriously，but our map shows that you're not alone， " he said.
