Environmental Science

Open, Seminar—Fall

Ecology is a scientific discipline that studies interactions between living organisms and their environments, as well as processes governing how species are distributed, how they interact, and how nutrients and energy cycle through ecosystems. Ecologists might ask questions about how plant growth responds to climate change, how squirrel population size or behavior changes in response to acorn availability, or how nutrients like nitrogen and phosphorous cycle in rivers and streams. In this course, students will develop a strong foundational understanding of the science of ecology at the individual, population, community, and ecosystem scales. Throughout the course, emphasis will be placed on how carefully-designed experiments and data analysis can help us find predictable patterns despite the complexity of nature. Students will be expected to design and carry out a field experiment, either individually or in small groups. The course will include a weekly lab, with most labs held outdoors.

Plants are all around us and are essential to life on Earth but are often overlooked or taken for granted. Especially as climate change and habitat loss threaten global biodiversity, understanding the biology of plants is fundamental to understanding the complex web of life on Earth. This course will be an introductory survey of botany. The first half of the course will cover topics such as plant anatomy, morphology, physiology, and reproduction; the second half will explore plant genetics, diversity, ecology, and evolution. Weekly discussions and textbook readings will be complemented by lab activities and a field trip to the New York Botanical Garden.

Humans are bathing in a sea of microbes. Microbes coat our environments, live within our bodies, and perform functions both beneficial and detrimental to human well-being. This course will explore the biology of microorganisms, broadly defined as bacteria, archaea, viruses, single-celled eukaryotes, and fungi. We will study microbes at multiple scales, including the individual cell, the growing population, and populations interacting with one another or their environments. Microbial physiology, genetics, diversity, and ecology will be covered in depth. Particular emphasis will be given to the role of microbes that cause infectious disease in humans and microbes that play critical roles in ecological processes. Seminars will be supplemented by a weekly lab section to learn key microbiological techniques and methods, most notably culturing and identifying bacteria.

With more than 350,000 known species, plants form the foundations of ecosystems and are crucial to life on Earth. This course will examine the diversity, ecology, and evolutionary history of major land plant groups—bryophytes, ferns, lycophytes, gymnosperms, and angiosperms. Through lectures, discussion of scientific literature, and hands-on investigation of live and preserved material, students will learn how to decipher botanical terminology; identify major plant families using diagnostic characters and dichotomous keys; analyze evolutionary relationships and adaptations across plant lineages; and investigate plant interactions with fungi, bacteria, animals, and their environment.

Nutrition is the sum of all interactions between us and the food that we consume. The study of nutrition includes the nature and general role of nutrients in forming structural material, providing energy, and helping to regulate metabolism. How do food chemists synthesize the fat that cannot be digested? Can this kind of fat satisfy our innate appetite for fats? Are there unwanted side effects, and why? What constitutes a healthy diet? What are the consequences of severely restricted food intake seen in prevalent emotional disorders such as anorexia and bulimia? These and other questions will be discussed. The course will also discuss the effect of development, pregnancy, emotional state, and disease on nutritional requirements. And students will also consider effects of food production and processing on nutrition value and food safety.

This course focuses on the intersection of economic development and environmental and natural-resource management. We will focus on the unique environmental and natural-resource challenges in the context of sustainable development, seeking to understand how economic development goals can be achieved without sacrificing the economic and environmental well-being of future generations. We will bring together relevant theoretical and empirical insights obtained from environmental economics, ecological economics, political economy, and development studies. A sample of guiding topics include: how the relationship between economic growth, demographic change, and environmental pollution has evolved; how to approach and deal with climate change in the context of sustainable development; how globalization distributes and redistributes environmental benefits and costs between the Global South and Global North; whether a Global Green New Deal can address both environmental sustainability and economic development; why developing countries suffer from the natural-resource curse; what local communities in developing countries can teach us about sustainable resource management; what property-right regimes work for sustainable development; and what renewable energy policies work for developing countries.

This seminar, broadly speaking, will cover introductory microeconomics and macroeconomics from a wide range of theoretical perspectives, including neoclassical, post-Keynesian, Marxian, feminist, and institutional political economy perspectives. The course will enable students to understand the more “technical aspects” of economics (e.g., usage of supply/demand analysis within and outside neoclassical economics), as well as significant economic history and the history of economic thought. Theoretical issues will be applied to contemporary policy debates such as industrial policy, foreign trade, global warming, and inequality.

This course is designed for students interested in the social sciences who wish to understand the methodology and techniques involved in the estimation of structural relationships between variables (i.e., regression analysis). The course is intended for students who wish to be able to carry out empirical work in their particular field, both at Sarah Lawrence College and beyond, and critically engage with empirical work done by academic or professional social scientists. In fall, the course will cover the theoretical and applied statistical principles that underlie Ordinary Least Squares (OLS) regression techniques. The course will begin with a review of basic statistical and probability theory, as well as relevant mathematical techniques. We will then study the assumptions needed to obtain the Best Linear Unbiased Estimates (BLUE) conditions of a regression equation. Particular emphasis will be placed on the assumptions regarding the distribution of a model’s error term and other BLUE conditions. The course will cover hypothesis testing, sample selection, and the critical role of the t- and F-statistic in determining the statistical significance of an econometric model and its associated slope or “β” parameters. Further, we will address three main problems associated with the violation of a particular BLUE assumption: multicollinearity, serial correlation, and heteroscedasticity. We will learn how to identify, address, and remedy each of these problems. In addition, the course will take a similar approach to understanding and correcting model specification errors. In spring, the course will build on fall learning by introducing advanced econometrics topics. We will study difference-in-difference estimators, autoregressive dependent lag (ARDL) models, co-integration, and error correction models involving nonstationary time series. We will investigate simultaneous equations systems, vector error correction (VEC), and vector autoregressive (VAR) models. The final part of the course will involve the study of panel data, as well as logit and probit models. Students will receive ample exposure to concrete issues while also being encouraged to consider basic methodological questions, including the debates between John Maynard Keynes and Jan Tinbergen regarding the power and limitations of econometric analysis. Spring is particularly relevant to students who wish to pursue graduate studies in a social-science discipline but equally relevant for other types of graduate degrees that involve knowledge of intermediate-level quantitative analysis. The practical “hands-on” approach taken in this course will be useful to those students who wish to do future conference projects, internships, or enter the job market in the social (or natural) sciences with significant empirical content. The goal is for students to be able to analyze questions such as: What is the relationship between slavery and industrialization in the United States? What effects do race, gender, and educational attainment have in the determination of wages? How does the female literacy rate affect the child mortality rate? How can one model the effect of economic growth on carbon-dioxide emissions? What is the relationship among sociopolitical instability, inequality, and economic growth? How do geographic location and state spending affect average public-school teacher salaries? How does one study global inequalities in terms of access to COVID-19 vaccines?

As the desire to engage in individual and collective efforts toward sustainable and climate-change mitigating solutions increases, this workshop offers an opportunity for students to explore the multiple ways in which “sustainability” can be fostered and developed at an institution like Sarah Lawrence College. Students will work in small groups on a variety of projects and produce research and educational material that can lead to concrete and actionable proposals for the College and our community to consider. Students will determine their own areas of interest and research, from energy and water-usage monitoring to composting solutions, recycling/reusing and consumer sobriety, landscaping choices, pollinators and natural diversity, food growing, natural and human history of the land, and community collaborations, to name a few. As part of their project efforts, students will engage with College administrators who are actively working toward sustainable solutions, as well as students, staff, and faculty groups such as the Warren Green vegetable garden, the Sarah Lawrence Interdisciplinary Collective on the Environment (SLICE), and the Sustainability Committee. We will also explore the possibility of writing grants in coordination with other actors at the College. Most of the course work will happen during class time. Skills in areas of any expertise are welcome, from environmental science to writing to visual and studio arts—but any interest in issues of sustainability and a strong sense of dedication will suffice.

Our existence lies in a perpetual state of change. An apple falls from a tree, clouds move across expansive farmland, blocking out the sun for days; meanwhile, satellites zip around the Earth, transmitting and receiving signals to our cell phones. Calculus was invented to develop a language to accurately describe the motion and change happening all around us. The ancient Greeks began a detailed study of change, but they were scared to wrestle with the infinite; so it was not until the 17th century that Isaac Newton and Gottfried Leibniz, among others, tamed the infinite and gave birth to this extremely successful branch of mathematics. Though just a few hundred years old, calculus has become an indispensable research tool in both the natural and social sciences. Our study begins with the central concept of the limit and proceeds to explore the dual processes of differentiation and integration. Numerous applications of the theory will be examined. Weekly group conferences will be run in hands-on workshop mode. This course is intended for students interested in advanced study in mathematics or sciences, students preparing for careers in the health sciences or engineering, and any student wishing to broaden and enrich the life of the mind.

Variance, correlation coefficient, regression analysis, statistical significance, and margin of error—these terms and other statistical phrases have been bantered about before and seen interspersed in news reports and research articles. But what do they mean? How are they used? And why are they so important? Serving as an introduction to the concepts, techniques, and reasoning central to the understanding of data, this course will focus on the fundamental methods of statistical analysis used to gain insight into diverse areas of human interest. The use, misuse, and abuse of statistics will be the central focus of the course; and specific topics of exploration will be drawn from experimental design theory, sampling theory, data analysis, and statistical inference. Applications will be considered in current events, business, psychology, politics, medicine, and many other areas of the natural and social sciences. Statistical software will be introduced and used extensively in this course, but no prior experience with spreadsheet technology is assumed. Group conferences, conducted in workshop mode, will serve to reinforce student understanding of the course material. This course is recommended for any student wishing to be a better-informed consumer of data, and strongly recommended for those planning to pursue advanced undergraduate or graduate research in the natural sciences or social sciences.

Calculus is the mathematical gift that keeps on giving—thank you, Newton and company! In this course, students will expand their knowledge of limits, derivatives, and integrals with concepts and techniques that will enable them to solve many important problems in mathematics and the sciences. By the end of the course, students will be able to judge whether answers provided by engine services such as WolframAlpha or ChatGPT are correct. Topics will include differentiation review, integration review, integration with non-polynomial functions, applications of integration (finding area, volume, length, center of mass, moment of inertia, probability), advanced techniques for integration (substitution, integration-by-parts, partial fractions), infinite sequences, infinite series, convergent and divergent sums, power series, differential equations and modeling dynamical systems, and, time permitting, parametric equations of a curve and polar coordinates. Students will work on a conference project related to the mathematical topics covered in class and are free to choose technical, historical, crafty, computational, or creative projects.

One of the biggest challenges that humanity currently faces is the need to revamp our energy systems to avoid the most hazardous impacts due to global warming. Unfortunately, our predominately carbon-based energy system—the largest source of greenhouse gases from human activities in the United States—has significantly contributed to climate change. One of our best chances to mitigate environmental impacts is to switch to renewable, and ideally carbon-free, energy systems. Using both theory and experiments, we will explore the physics behind current renewable energy systems—including geothermal, wind, solar, and nuclear fission—as well as investigate the future potential of the hydrogen strategy and nuclear fusion. We will look at both the practical challenges and the potential promises of decarbonizing global energy production to become more informed consumers and citizens in our rapidly changing world. While students are not expected to have taken any physics courses before this course, a basic comfort with algebra is desirable and a natural curiosity to learn is essential.

We encounter temperature on a daily basis when we check our weather apps and have undoubtedly heard discussions about the greenhouse effect and Earth’s warming climate. But what do scientists mean by warming? How can they model it? And what even is temperature? In this course, we will dig into the fascinating world of thermal physics, which is important for delving into many more advanced topics in physics, geosciences, or chemistry. Topics will include: thermodynamics, including energy, temperature, work, heat, and ideal gases; statistical mechanics, including entropy, partition functions, distributions, chemical potential, nonideal gases, bosonic gas, and fermionic gas; and applications from physics, chemistry, and engineering, such as engines, refrigerators, Bose-Einstein condensates, black holes, and climate models. For conference work, students will be encouraged to model a simple thermal system of their choice, using the mathematical and numerical methods developed throughout the course.

Open, Concept—Spring

Over the last 50 years, ecofeminist artists have used means such as photography, performance, and community engagement as a way to approach ecological crises, using the body as a site of resistance, kinship, and violence. Methods such as deep listening, endurance performance, slow cinema, foraging and gathering, cartography, and communal urban gardens are just a few of the approaches of ecofeminist artists. These artworks address ecological issues of sustainability, extraction, and marginalization that impress both upon vulnerable bodies and the nonhuman world. Many of these works fall within an economy of care, which we will examine as gendered and racialized work. This course is an art class, with an emphasis on reading and discussion. This course will research and discuss artists whose work combines feminist and ecological themes. We will look, listen, and read seminal works of artists, with a focus on primary sources such as artist and theorist writings, artwork, and interviews—and with a goal in mind to synthesize and respond to this subject in our own works. Each week will introduce a new topic or category of ecofeminist methodology. Each week will include a discussion board and a thematic exercise. The course will culminate in a final project.
