PORTLAND — Two student teams from Moore Middle School will participate in the Project Citizen State Showcase at the State House in Augusta on May 7.

The Moore teams will present public policy research projects on school energy use and high school dropout prevention, school district officials announced today.

Cape Elizabeth, Windham, Boothbay, Holden, Calais and Swan’s Island also will send teams to the showcase, according to KIDS Consortium, an Auburn nonprofit that coordinates the annual event.

Through Project Citizen, students identify and address problems in their communities by researching possible solutions, making recommendations and creating an action plan.

Teams from Moore have won the state showcase three times in the last 10 years.

This year, Moore students tackled a variety of issues, including graffiti, milfoil, abusive teen relationships and factory farming.

The energy-use team scored the most points in a local showcase. Team members are Josh Brown, Ethan Pierce, Miranda Richman, Delaney Stokes and Christopher Wittig.

The dropout-prevention team took second place in the local showcase. Its members are King Cua, Georgia Drew, Olivia Gilbert, Abdi Sulub, Bryanna Trott and Alyssa Vaccaro.
