Carrabec group studies effects of altitude and exercise on heart rate
The Carrabec High School anatomy and physiology class and advanced physical education class conducted a lab experiment where students recorded and studied the effects of exercise and altitude on heart rate and blood pressure. The first phase of the lab was conducted at the Summit building on top of Sugarloaf Mountain at 4,200 feet altitude. The Sugarloaf staff graciously provided transportation up and down the mountain with their snow cat. Once the students settled into the environment, they took their homeostatic blood pressure and pulse rates. These were done with newly-acquired digital blood pressure cuffs and heart monitors purchased through This group of Carrabec High School students participated in an experthe Oak Grove/Coburn Grant iment to monitor heart rate and blood pressure from exercise at high awarded to Carrabec this past altitudes.

Norridgewock student raises butterflies
by Lucille Greer Norridgewock Mill Stream School fifth grade student, Kessea Emerine-Hendren, displayed her Earth Day collection of Painted Lady Butterflies at the Skowhegan Community Center on Earth Day. Kessea's aunt, Barbara Blaisdell provided inspiration and the mesh cage for the 10 caterpillars which Kessea ordered. To everyone's delight nine of them hatched although only seven at the most were expected. From the accompanying information, Kessea learned that the butterflies open and close their wings when they are happy or need to cool, and they love to sleep upside down.
