The Great Patagonia Land Grab: A Case Study in International Biodiversity, Conservation, and Environmental Politics
Rating
0.0 stars

This PowerPoint case (~2.4 MB) was developed for an undergraduate, non-majors course in conservation biology. It explores the controversy surrounding land purchases in the Patagonia region of Chile and Argentina. According to local indigenous peoples, wealthy individuals are purchasing their ancestral land and then forcing them to leave. Individual landowners and international environmental groups wish to preserve the pristine ecosystems that remain in Patagonia. This case serves as an introduction to stakeholder controversy, the international dimensions of environmental policy, public versus private ownership for environmental protection, and conflict resolution.

Habitat Mapping
Rating
0.0 stars

The marine environment is unique and requires technologies that can use sound to gather information since there is little light underwater. The sea-floor is characterized using underwater sound and acoustical systems. Current technological innovations are allowing scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles allows scientists to map and understand the sea floor, and in some cases, the water column. In this lesson, the students will be shown benthic habitat images produced by GIS. These imaged will lead to a class discussion on why habitat mapping is useful and how current technology works to make bathymetry mapping possible. The teacher will then ask inquiry-based questions to have students brainstorm about the importance of bathymetry mapping.

Heat Transfer Lesson
Rating
0.0 stars

Students explore heat transfer and energy efficiency using the context of energy efficient houses. They gain a solid understanding of the three types of heat transfer: radiation, convection and conduction, which are explained in detail and related to the real world. They learn about the many ways solar energy is used as a renewable energy source to reduce the emission of greenhouse gasses and operating costs. Students also explore ways in which a device can capitalize on the methods of heat transfer to produce a beneficial result. They are given the tools to calculate the heat transferred between a system and its surroundings.

How Dense Are You?
Rating
0.0 stars

Students learn about geotechnical engineers and their use of physical properties, such as soil density, to determine the ability of various soils to offer support to foundations. In an associated activity, students determine the bulk densities of soil samples, and assess their suitability to support foundations.

Improving on Nature?
Rating
0.0 stars

In 1958, black bass were introduced into Lake Atitlan in the highlands of western Guatemala as a way to attract tourism and boost the local economy, but unforeseen complications resulted in an ecological disaster. Developed for an introductory course in biology, this case study first casts students in the role of the local population at that time and asks them to judge the proposal to introduce the new species of fish. The students then review the ensuing events from a historical perspective based on additional information they receive from the instructor in a progressive disclosure format.

Introduction to Environmental History, Spring 2011
Rating
0.0 stars

Focusing primarily on the period since 1500, explores the influence of climate, topography, plants, animals, and microorganisms on human history and the reciprocal influence of people on the environment. Topics include the European encounter with the Americas, the impact of modern technology, and the historical roots of the current environmental crisis.

Introduction to Evolutionary Biology and Ecology
Rating
0.0 stars

This course describes biological changes that happen on a very large scale, across entire populations of organisms and over the course of millions of years, in the form of evolution and ecology. Upon successful completion of this course, students will be able to: Use their understanding of Mendelian genetics and patterns of inheritance to predict genotypes and phenotypes of offspring or work backwards to identify the genotypes and phenotypes of a parental generation; Distinguish between inheritance patterns that involve autosomal vs. sex-linked traits and identify the respective consequences of each type of inheritance; Identify what distinguishes DarwinĺÎĺĺÎĺs theory of evolution from other arguments that attempt to explain diversity across species and/or many generations; Identify which of many types of natural selection is acting on a particular population/species; Identify which of many types of sexual selection is acting on a particular population/species; Identify the factors that alter the frequencies of alleles in populations over time and describe the effects of these factors on populations; Recognize, read, and create phylogenies and cladograms, using them to explain evolutionary relationships; Determine the ecological interactions affecting a particular community and identify the effects of specific relationships (e.g. symbiosis, competition) on species within that community; Distinguish between world biomes in terms of their climate, nutrient cycles, energy flow, and inhabitants; Use their knowledge of nutrient cycles and energy flow to estimate the effect that changes in physical or biological factors would have on a particular ecosystem.

Introduction to Evolutionary Biology and Ecology - Laboratory
Rating
0.0 stars

This lab course supplements ĺÎĺĺĺŤIntroduction to Evolutionary Biology and EcologyĄ_ĺĺö. Although it does not replicate a true lab experience, it does encourage greater familiarity with scientific thinking and techniques, and will enable exploration of some key principles of evolutionary biology and ecology. This lab supplement focuses on visual understanding, application, and practical use of knowledge. In each unit, the student will work through tutorials related to important scientific concepts and then will be asked to think creatively about how that knowledge can be put to practical or experimental use. Upon successful completion of this lab supplement, the student will be able to: Display an understanding of Mendelian inheritance as applied to organisms in virtual experiments; Describe the process of natural selection and understand how it will alter populations over generations and under a variety of selection pressures; Understand how the process of speciation is affected by isolation and selection pressures; Understand predator-prey dynamics under a variety of ecological conditions; Distinguish between biomes in terms of their structure/climates as well as the types and diversity of organisms that inhabit them.

Students design and conduct simple experiments using elodea (aquatic plant sold in pet stores) and Bromthymol blue to determine whether plants consume or release carbon dioxide in the process of photosynthesis. Students will record their data which will be used to conclude whether carbon dioxide was consumed or released by the elodea. Through class discussion of student data, students will learn that carbon dioxide was consumed during photosynthesis.
