This course presents the mechanical, optical, and transport properties of polymers with respect to the underlying physics and physical chemistry of polymers in melt, solution, and solid state. Topics include conformation and molecular dimensions of polymer chains in solutions, melts, blends, and block copolymers; an examination of the structure of glassy, crystalline, and rubbery elastic states of polymers; thermodynamics of polymer solutions, blends, crystallization; liquid crystallinity, microphase separation, and self-assembled organic-inorganic nanocomposites. Case studies include relationships between structure and function in technologically important polymeric systems.

This group research project serves as the focus for our introductory Earth Systems Science classes. Each of four to six lab sections of 15-25 students collect discharge, sediment load, and water chemistry data from a different site along a local river, and compare their data to that collected in previous years and at other sites along the river. The project incorporates topographic map reading and graphing as well as collecting and analyzing data, and presenting the results in oral and written form. Labs on rocks and minerals use samples from the project area to encourage students to make connections between the solid Earth and surface processes.
Each component of the Florida River Project is described below, with a link to the activity sheet and related files.

A second semester introductory physics course for life sciences students that looks to deepen students' understanding of biology and chemistry through physics all through the lens of understanding two of the most fundamental particles in the Universe: electrons and photons. The book begins with exploring the quantum mechanical nature of these objects to expand on what students have learned in chemistry and then proceeds to geometric optics (using the human eye as a theme), electrostatics (using membrane potentials), circuits (using the neuron), and finally synthesizing everything in a unit exploring the meaning of "light is an electromagnetic wave."

We help students see the connection between college level chemistry course work and their differential equations coursework. We do this through modeling kinetics, or rates of chemical reaction. We offer many opportunities to model these chemical reactions with data, some of which comes from traditional introductory chemistry textbooks. We ask students to verify their model through parameter estimation. We use Excel’s Trendline addition to graphs/charts to select the models for the data and transformed data to take advantage of Trendline’s set function choices and we also use Mathematica’s direct nonlinear fitting capabilities.

This ChemMatters article provides a history of the study of ozone, a description of an experimental simulation called "The World Avoided," a brief introduction to the chemistry of ozone, an explanation of how ozone is measured, and the difference between "good" ozone in the stratosphere vs "bad" ozone in the troposhere. ChemMatters is an educational magazine published by the American Chemical Society.

You probably remember the mole from high school chemistry, but do you remember why it is useful to chemists? The goal of the following video is to give the "big picture" of the mole and its applications; information on how to use the mole in calculations can be found in another tutorial. Throughout this course, we will use the term "molecular weight" to refer to the mass of a mole of a substance (for instance, the molecular weight of oxygen (O2) is 32 g/mol). Recent textbooks refer to this as "molar mass" to emphasize (i) that this term refers to the mass, not the weight, of substance, and (ii) that the quantity refers to a mole of a substance, not a single molecule. "Molecular weight" may be less precise, but it remains the term that most practicing chemists use in the laboratory. For this reason, we continue to use "molecular weight" in this course.

This assignment offers students several problems that help them understand the basic of mixing models and their use in understanding the controls on water quality in the environment. The purpose of the assignment is to help students integrate across the various topics in environmental chemistry in the context of flow and transport. Students will hopefully learn how reactive and non-reactive tracers can be used in conjunction to fully understand a chemical system.
