Thursday Evening Lecture Series

This winter and spring, you can join us in exploring water in Minnesota during a four-part Thursday evening lecture series. Experts from around North America will offer their insights into the history, science, and cultural impact of this essential resource, proving that, as individuals and community members, we have the power to protect this most precious natural resource.

Chemicals in our 10,000 Lakes: Should we be worried?
Dr. Deborah L. Swackhamer, Water Resources Center, University of Minnesota
Thursday, March 12, 2009

Minnesota has more water resources than any other of the lower 48 states, but we also know that our lakes and rivers contain chemical pollutants such as pesticides and hormone mimics. Come hear about where they come from, why they are a problem, and what we can do about them.

The river we have wrought: Two centuries of human impact on water quality in the upper Mississippi River
Dr. Daniel Engstrom, St. Croix Watershed Research Station
Thursday, March 19, 2009

Human activity has dramatically altered the natural landscape of Minnesota over the past 200 years. Find out how scientists at the Science Museum of Minnesota's St. Croix Watershed Research Station have reconstructed a detailed picture of the pre-settlement Mississippi River from the sediments accumulating in Lake Pepin.

Minnesota's Water Resources: Impacts of Climate Change
Dr. Lucinda Johnson, National Resources Research Institute, University of Minnesota - Duluth
Thursday, April 9, 2009

Over the past 150 years, Minnesota's climate has become increasingly warmer, wetter, and variable, resulting in undeniable ecological impacts. For example, more recent changes in precipitation patterns combined with urban expansion and wetland losses have resulted in an increase in the frequency and intensity of flooding in parts of Minnesota. Learn about exciting new research which will develop a prediction model for future climate changes specific to Minnesota, and discover its potential economic and civic impact.

Tickets for each Water lecture are $12 per person ($8 per Science Museum member).Lectures will take place from 7 to 8:30 p.m. in the Science Museum's auditorium on Level 3. Space is limited. For more information or to reserve tickets, call (651) 221-9444.
