Upper School students at The Wardlaw+Hartridge School in Edison conducted a special activity in their advisory sections on Sept. 11.

After discussing the historical and biographical context of 9/11, students watched a video of people born on the day of the attacks. They pledged to do one good deed on 9/11 to make the world a better place.

Students wrote those deeds on Post-It notes and posted them on a taped outline of the twin towers. They also shared their images on social media using the hashtag #wh911day.
