READFIELD --As a sea of yellow, pink and blue programs waved back and forth in the crowd -- graduates' friends and family desperately trying to cool off used their programs to fan themselves at Maranacook Community High School's graduation -- teacher Steve DeAngelis encouraged graduates to make some waves of their own.

"If each of us commits to a lifetime of making ripples in our community, together, we can make a tidal wave," the veteran physics teacher told graduates. "My friends in the class of 2008, Maranacook Community School has been changed because you were here. And I know each community you live in will be, too. Make waves. And be the catalyst for positive change in your communities. That is how you will change the world."

Maranacook's 125 graduates, each wearing black or white robes, marched to get their diplomas in the steamy school gym packed tight with their loved ones, teachers, and other well-wishers Sunday afternoon.

DeAngelis spoke before Maranacook's salutatorian -- his daughter Hannah DeAngelis -- took to the podium.

Hannah DeAngelis noted she and her fellow graduates were shaped by events such as the Sept. 11 terrorist attacks.

She encouraged her classmates to speak out.

"The power of the individual still exists," she said. "We have the power to be bold, daring. Audacious even."

Valedictorian Claire Marvinney described the many times in school students' heartbeats raced -- before tests, during sporting events, or when making a connection with "that special someone."

"These are heartbeats that will last us through full, successful lives," she said.

Principal Carol Fritz, saying many members of the class of 2008 are already working to protect the environment, said "I'm hopeful, as you join the adult world, you'll continue to keep the earth in mind."

The gym appeared to be standing-room-only for the event. Camera-toting relatives vied for good spots to snap photos of their graduates as they entered and marched to their seats for the ceremony.

Many teachers exchanged hugs with their students as their diplomas were awarded.
