HYDROPHONE CREATIVE EXPRESSION On a cruise last spring, which was the maiden trip for the MLCI hydrophone, Nobleboro students had some creative fun. Someone decided it might be interesting to try and scream underwater with the hydrophone nearby. It worked wonderfully and then we really got creative. Ask us about our efforts to burp underwater. Don't you just love junior high kids??

NOBLEBORO LAKE POETRY Poems by Josh Q Damariscotta Lake, For fishing and swimming, Water skiing and tubing. At Camp Kieve kids are learning About the ways of the native tribes. About how they lived and how they died. At Pemaquid Pond, You have so much fun when you’re swimming in the sun. You laugh and play all day until you get tired. You dry off and go home. You had so much fun You’re going again tomorrow.

MORE LAKE POETRY Damariscotta Mills A poem By Dennis B. Damariscotta Mills. Fun for all, even if you’re short or tall. The alewives are streaming. Soon food for the widows. A tradition that started in 1807.

TEMERATURE DIFFERENCE IN LAKE LEVELS There are three different layers in a lake, the epilimnion, the thermocline, and the hypolimnion. The epilimnion is the top layer, the thermocline is the middle, and the hypolimnion is the bottom layer. In the summer the epilimnion circulates warm water and most of the fish stay in that zone which can go down to 20 ft. The thermocline doesn’t have as much oxygen so fish don’t stay in that zone. The hypolimnion has little or no oxygen circulation so fish can’t live or survive down there. In the winter, the bottom is warmer than the surface so fish can inhabit near the bottom. In the spring and fall the water stays the same temperature on the bottom and surface of the water, but the water is warmer in the fall. by Rhiannon, Anna, Heather, Hannah

MLCI DAM BUILDING DAY - JANUARY 17, 2008          On January 17, 2008 Maine Lakes Conservancy Institute Lake Science Educators showed up for a dam building exercise.  Nobleboro Central School eighth graders were treated by MLCI's Rex and Phil to an hour long dam building extravaganza.  Students either built a human made dam or a beaver dam and then modeled water interaction.  The dialog was rich around the environmental impact of both beaver and human construction.  Students had lots to say about beaver dams in Nobleboro and making sure that forestry activity does not harm the very important local watersheds.     Thanks to Rex and Phil for building a "dam" good experience......     Please see photos of our work below.      Four Nobleboro Students hard at work building a stream and dam. NCS students experiment with their stream and beaver dam.
