DARTMOUTH - FAx Talks, student lectures about topics such as education, culture, science and social justice based on the internationally-known TED Talks, a global initiative about ideas worth spreading, came to Friends Academy last week. The expert speakers on the wide-ranging list of topics were 22 eighth-graders from Marlaina Trepanier’s English classes, who spent months researching their lecture subjects, writing presentations and slide shows, and memorizing the prepared talks in anticipation of the Feb. 2 event in the school commons.
