WILTON — Friends of Wilson Lake and the Maine Lakes Society once again brought a floating classroom to fourth grade Academy Hill School students.

On Friday, June 7, students took turns boarding the MLS research boat the Melinda Ann to learn firsthand about tests and readings taken from Wilson Lake that help monitor water quality. While one group of students was on the water, remaining students participated in various activities in Bass Park.

On Wilson Lake, some parameters are monitored year–round with help from University of Maine at Farmington students. Data comparisons are used to determine changes in the lake’s water quality.

As the first group of students headed out on Wilson Lake, FOWL member Sandy Muller said a group of town officials would be taking a tour Saturday similar to what the students were experiencing.

“Not just lake people signed up for the tours. Officials want to see what’s going on. We’re real pleased with that,” she said.

  • A remote operated vehicle with a 150–foot tether, a camera with thruster and lights and a video monitor for a wonderful underwater view of the lake and its inhabitants at various levels.
  • A plankton tow that collects samples of zooplankton bringing them to the boat for viewing using a Ken–a–Vision microscope projector.
  •  A water column sampler to demonstrate how one can take samples of the water at various depths.
  •   A dissolved oxygen probe to compare oxygen levels and water temperature at different depths.
  •   An Aqua–Scope and Secchi Disk to learn how water clarity is monitored throughout the summer.

Students helped collect data using the various equipments.

At Bass Park, AHS teacher Morgan Badeau said students could rotate through several stations including board and bat games, paper airplanes, art in the park and a watershed demonstration table.

“We study the environment in class, do the water cycle. Jen Jespersen of with Ecological Instincts, who has been involved with Wilton’s watershed survey and grant projects resulting from survey results, talked with the students about water ecology and how to protect the environment.

“We did a salmon release in the Sandy River. About 160 fry were released before Memorial Day weekend,” she said.

Students learned how to make paper airplanes then tested how different variations in design affected flight distance.

Art supplies were used to create replicas of trees, rocks and other natural things observed in the park.

The swing sets and other playground equipment also saw much use.

Jespersen talked about watersheds and how erosion can lead to pollution. The students took turns changing the watershed demonstration table to see different forms of erosion and the resulting impacts.

“It’s always exciting to see kids learn about their environment, things that are local,” Badeau said.
