"More than two decades later, 9/11 continues to shape American life. Museums, memorials, and annual remembrance ceremonies honor the people who died, the first responders who went into the towers and fires when everyone else was trying to leave, and the communities that rebuilt afterward. By learning about this day and the stories of those who lived through it, students can better understand how one day can change a nation and why its important to remember what happened. Through firsthand stories, historical information, and critical thinking questions, youll learn what happened that day and why it still matters today"-- Provided by publisher.
