About 150 middle-school students from across Maine were in Portland on Friday to participate in community service projects and a scavenger hunt in the Old Port.

The eighth-graders are enrolled in Jobs for Maine’s Graduates, a nonprofit organization that’s helping to prepare more than 4,000 middle- and high-school students for continued education and careers.

In the “urban adventure,” students went from one downtown business to another, searching for items such as business cards and job applications. The hunt was designed to promote teamwork, communication skills and future employment opportunities.

The students also worked on community service projects for Ruth’s Reusable Resources, Camp Susan Curtis and Portland High School.
