This activity is a field investigation where students find out what makes up soil.

This is a field investigation on diversity of life where students count the number of kinds organisms in two locations. Students report their results on posters and propose reasons why there might be difference in diversity between the locations.

Using dilemma cards describing some of the issues affecting Yellowstone National Park, students work in small groups to consider management issues that meet both of the conflicting mandates that the National Park Service must follow." There are 6 dilemmas that the class can be broken into groups to research. These dilemmas include wolf reintroduction, bison diseases, non-native trout, wildfires, resource sharing, and winter use of park lands. After researching each dilemma, students will make a pros/cons list, a final decision, and a brief presentation to the class. While the website recommends completing this lesson "after the expedition" to Yellowstone park, it can be done without visiting the park.

This field investigation allows students to collect and observe earthworms using liquid extraction to help develop background knowledge at the start of a new earthworm unit.

This activity is an in class lab where students will compare different acid solutions on seed germination and growth.

Students test the question, "Do eggs balance on the equinox?" Students develop their own procedure, analyze their data and come up with their own conclusions.

This classroom activity introduces students to energy flow through organisms, producers & photosynthesis, and consumers & respiration.

Examines theories and practice of environmental justice, concerns about race, poverty, and the environment in both domestic and international contexts, exploring and critically analyzing philosophies, frameworks, and strategies underlying environmental justice movements. Examines case studies of environmental injustices, including: distribution of environmental quality and health, unequal enforcement of regulations, unequal access to resources to respond to environmental problems, and the broader political economy of decision-making around environmental issues. Explores how environmental justice movements relate to broader sustainable development goals and strategies. This class explores the foundations of the environmental justice movement, current and emerging issues, and the application of environmental justice analysis to environmental policy and planning. It examines claims made by diverse groups along with the policy and civil society responses that address perceived inequity and injustice. While focused mainly on the United States, international issues and perspectives are also considered.

A general introduction to the diverse roles of microorganisms in natural and artificial environments. Topics include: cellular architecture, energetics, and growth; evolution and gene flow; population and community dynamics; air, water, and soil microbiology; biogeochemical cycling; and microorganisms in biodeterioration, bioremediation, and pest control.

In this unit, we describe the theory of evolution by natural selection as proposed by Charles Darwin in his book, first published in 1859, On The Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it.

This course will look at the various mechanisms of evolution, how these mechanisms work, and how change is measured. The course will begin by reviewing the evolutionary concepts of selection and speciation. The student will then learn to measure evolutionary change and look at the history of life according to the fossil record and a discussion of the broad range of life forms as they are currently classified. Upon completion of this course, students will be able to: define evolution and describe different types of selection; provide examples of microevolutionary forces and describe how they impact the genetics of populations; describe the Hardy-Weinberg principle and solve problems related to Hardy-Weinberg equilibrium; provide examples of games used in evolutionary game theory; connect biological phenomena to game theory; develop simple phylogenies from molecular or morphological data; identify important evolutionary events that have occurred throughout geologic time; characterize and provide examples of major plant and animal phyla.

Seminar covering topics of current interest in biology. Includes reading and analysis of research papers and student presentations. Contact Biology Education Office for topics.

7.02 and 7.021 require simultaneous registration. Application of experimental techniques in biochemistry, microbiology, and cell biology. Emphasizes integrating factual knowledge with understanding the design of experiments and data analysis to prepare the students for research projects. Instruction and practice in written communication provided.

This course is the scientific communications portion of course 7.02, Experimental Biology and Communication. Students develop their skills as writers of scientific research, skills that also contribute to the learning of the 7.02 course materials. Through in class and out of class writing exercises, students explore the genre of the research article and its components while developing an understanding of the materials covered in the 7.02 laboratory.

" In this class, students engage in independent research projects to probe various aspects of the physiology of the bacteriumĺĘPseudomonas aeruginosa PA14, an opportunistic pathogen isolated from the lungs of cystic fibrosis patients. Students use molecular genetics to examine survival in stationary phase, antibiotic resistance, phase variation, toxin production, and secondary metabolite production. Projects aim to discover the molecular basis for these processes using both classical and cutting-edge techniques. These include plasmid manipulation, genetic complementation, mutagenesis, PCR, DNA sequencing, enzyme assays, and gene expression studies. Instruction and practice in written and oral communication are also emphasized.

Laboratory uses yeast as an experimental system to study fundamental problems in understanding cell cycle and chromosome segregation. Experimental work combines genetic approaches with the tools of molecular and cell biology to identify and characterize novel genes that act on these processes. Instruction and practice in written and oral communication provided.

Designed for students without previous experience in techniques of cellular and molecular biology, this class teaches basic experimental techniques in cellular and molecular neurobiology. Experimental approaches covered include tissue culture of neuronal cell lines, dissection and culture of brain cells, DNA manipulation, synaptic protein analysis, immunocytochemistry, and fluorescent microscopy.

This activity allows elementary students to construct a decomposition column in order to observe the relationship between living systems and energy sources.

This activity allows children to explore the effects of oil spills on birds.

This is a 4-5 day set of activities that uses a systems thinking approach to teach students about the various components of ecosystems as well as the different roles that organisms have within the ecosystem.
