People in Context:  Reexamining Population Debates in the 21st Century

Monday, 17 April, 11 a.m. MT

After an extended hiatus, the issue of the global human population is once again receiving attention. Major scientific organizations are revisiting the subject and calling for its return to environmental, political, and economic discussions. However, what “the issue population” means is relative to how it is framed and discussed. A cursory examination of its past designations in politics, economics, and environmental philosophy shows its significance, but a historical understanding of the population problem can help re-contextualize the issue of population for the purpose of reconstructing and redirecting inquiry. A rethinking of the debate should consider 21st century challenges, such as the problem of scale and stabilization, the environmental, sociopolitical and economic challenges brought about by current demographic trends, and the need for a critical examination of our values and habits in effecting meaningful social change while providing an ecologically sustainable world for seven billion persons and counting.

Celestial Connections:  Vincent Van Gogh’s The Starry Night and the Pedagogy of Astronomy

Tuesday, 18 April, 11 a.m. MT

Vincent van Gogh’s The Starry Night (1889) is one of the most famous works of art in the world; its beautiful, swirling night sky familiar to us all. In this presentation, I will discuss the history of the picture and highlight just some of the ways in which the work functions as an excellent exemplar of the potential for pedagogical cross-pollination between the humanities and other academic disciplines, with a focus upon astronomy.

She has extensive experience teaching the history of art and the humanities at a university level. Recently she has published several articles on Netherlandish painters active during the Tudor era in a variety of peer-reviewed journals and books. Her website, HansEworth.com, functions as a catalogue raisonné of one such artist. In her personal time, Hope enjoys reading, travel, gold panning, and photography; she lives in Washington with her boyfriend, John, and her cat, Couie.

Purposeful Alternatives to Protest: Engaging & Educating the Public about Science

Wednesday, 19 April, 12:00p.m. MT

While not every scientist or science educator is able to “March for Science” nationwide on Saturday 22 April, there are many opportunities every day to keep science in public view and under friendly gaze. In the short term, give the public positive experiences with community participation, citizen science, and common ground. In the long term, provide support for pro-science views, organizations, and people, including political candidates.

Really?  Vaccination Reduces Population Growth and, thus Climate Change

Wednesday, 19 April, 7:00 p.m. MT

Join me to learn how vaccines work and why global vaccination campaigns reduce population growth. In turn, reduced populations lead to reduced climate change, reduced global instability due to pressures on natural resources and children living healthier and longer lives in developing and developed countries.

 

Kara Lukin, Ph.D.
Course Mentor, General
Education, Natural Science

Dr. Kara Lukin holds a BA in biology and international relations from Smith College and a PhD in immunology from the University of Colorado. She has 20 years of experience in biological research and science education (K-24). Her scientific research spans the development and survival of cells of the immune system, childhood leukemia and peroxisome-related genetic disorders. Kara created a program for teachers to translate their own authentic scientific research into the classroom and remains active in STEM outreach. She believes engaging strategies which harness people’s interests to build effective, active learning strategies allows everybody to master science and apply it to improve their lives and communities.

 

 

Jeff Edmunds, Ph.D.
Course Mentor, General
Education

Dr. Jeff Edmunds holds a BA in mathematics from Portland State University and a PhD in mathematics from the University of Arizona. His research focuses on mathematical modeling of competing species. An article that he published in 2003 in the Journal of Animal Ecology on the competitive exclusion principle received a write-up on the cover of SIAM News, the monthly newsletter of the largest international organization of applied mathematicians. Jeff has taught introductory mathematical modeling with a focus on environmental awareness, and developed a course on mathematical modeling for high school teachers in a master’s degree program. He believes that tying mathematics to relevant applications is a great way to increase student motivation.

 

Tropic Cascades and Biodiversity:  The Importance of Eating and Being Eaten
A look at predator/prey relationships and what happens when a group doesn’t come to the table.

Thursday, 20 April, 11:30 a.m. MT

What are the community and ecosystem consequences of removing a species, either directly or indirectly through human activity?  Do you know that removing fish from ponds could decrease reproduction of terrestrial plants? Removing species from the food chain can affect species a few links away from the removed species. This effect is referred to as trophic cascade. During our presentation, we will introduce attendees to trophic cascades and the importance of each species in the food chain. Through examples, we will demonstrate the value of species to communities, ecosystems, and to us. We will show the importance of biodiversity through predator/prey relationships as they relate to community trophic structure.

Wetland Status in Minnesota since the 1850s

Friday, 21 April, 12:00 p.m. MT

Wetlands are among the most productive ecosystems in the world and are comparable to rain forests and coral reefs. Since statehood, Minnesota wetlands have decreased significantly in acreage. Beginning in the 1970s, Public policy has changed towards an emphasis of protection of these wetland resources. This positive attitude lead the Minnesota legislature to enact the Wetlands Conservation Act in 1991, which, in part, required a ‘no net loss’ of wetlands. In 2006, a statewide wetland-monitoring program was initiated to assess status and trends of both wetland quantity and quality.
