Educators from schools and nature centers are invited to apply for a free groundwater sand tank model and workshop (valued at $900). If you provide environmental educational programs for kids in grades 6 – 12 and want a hands-on tool that shows how groundwater moves, this model may be for you. Twenty models will be given away at two workshops. This year workshops will be held January 30th at the Wisconsin Geological and Natural History Survey Core Lab, 211 Blue Mounds Street, Mount Horeb, WI 53572; and February 20th at Bay Beach Wildlife Sanctuary, 1660 East Shore Drive, Green Bay, WI 54302. Workshops will be taught by staff from the Center for Watershed Science and Education and the Wisconsin Geological and Natural History Survey. Two teachers from a school or nature center must complete the application form describing how they will use the model. Money is available to reimburse schools for substitute teachers. The deadline for applications is November 7, 2018.
