Testing Tabletop Models for Lakes, Algae, and Plankton

Earlier this month we had a lot of fun testing a few of our hands-on tabletop activities. On the museum floor at the Lawrence Hall of Science, 70 people, ranging from elementary school-age children to adults, got a sneak preview of these new prototype activities and gave us their feedback to make them better. One of the tabletops we tested was the Seiche Wave Model. The model is a long, narrow tank that can be divided into sections for different colored water of different temperatures. Once the divider is removed, the different temperatures of water form layers, called thermoclines, based on density due to their temperature. By blowing air through straws, visitors saw how wind can make waves on a lake surface and also create internal waves, called seiche waves. Another favorite action children really enjoyed was pouring water through a tube to simulate how streams can produce seiche waves in a lake too.

Kids also liked playing the Algae and Plankton computer games. In this game, visitors learned how to identify different types of plankton and found out what kinds of phytoplankton zooplankton like to eat. Thanks to all the participants and their feedback, we know these activities are on the right track in nurturing curiosity and raising awareness about lakes and we’ve also gained some ideas on how to improve them.

ACTION LAB, ECHO’s Newest Exhibit Space Opens Designed for Teens and Adults with Cutting Edge 3D Technology

ECHO Lake Aquarium and Science Center, Leahy Center for Lake Champlain, will be celebrating the opening up its newest exhibit space, Action Lab Saturday, May 18 from 10 a.m. to 5 p.m..

ECHO’s new Action Lab exhibition, located on the top floor at ECHO will be open every day! What is an Action Lab and why create one? It is a space specifically designed to encourage and teach citizen science participation to teens and adults using a combination of state-of-the-art technology and hands-on experiments!

”ECHO’s decision to build this space has evolved over the past ten years. We listened to the community and we heard them say the same thing, they all want Lake Champlain to be a healthy resource for everyone, including all the animals and plants that call it home. The Action Lab allows the community to be engaged in making a positive difference in the health of the Lake. They will be able to fully understand all the Lake’s dynamics – from the origin of a blue-green algae bloom to the threats to the spiny softshell turtles that inhabit the Lake,” said ECHO Executive Director, Phelan Fretz.

Julie Silverman is ECHO’s Director of New and was the developer and construction manager for the Action Lab.

“What the new Action Lab allows us to do is to continually pioneer ways to engage our guests in local issues facing our community and the diverse breadth and beauty of the Lake Champlain Basin. By using cutting edge technology tools and ever-changing citizen science programs we are able to introduce dynamic ways our citizens can be involved in Lake stewardship,” said ECHO’s Director of New, Julie Silverman.
