This Protein Purification video lesson is intended to give students some insight into the process and tools that scientists and engineers use to explore proteins. It is designed to extend the knowledge of students who are already somewhat sophisticated and who have a good understanding of basic biology. The question that motivates this lesson is, ''what makes two cell types different?'' and this question is posed in several ways. Such scientific reasoning raises the experimental question: how could you study just a subset of specialized proteins that distinguish one cell type from another? Two techniques useful in this regard are considered in the lesson.

Hitherto it had gone by the original Indian name Manna-hatta, or as some still have it, 'The Manhattoes'; but this was now decried as savage and heathenish... At length, when the council was almost in despair, a burgher, remarkable for the size and squareness of his head, proposed that they should call it New-Amsterdam. The proposition took every body by surprise; it was so striking, so apposite, so ingenious. The name was adopted by acclamation, and New-Amsterdam the metropolis was thenceforth called. --Washington Irving, 1808 In less tongue-in-cheek style, this course examines the evolution of New York City from 1607 to the present. The readings focus on the city's social and physical histories, and the class discussions compare New York's development to patterns in other cities.

This collection uses primary sources to explore the Bracero Program. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

Students explore the relationships between genetics, biodiversity, and evolution through a simple activity involving hypothetical wild mouse populations. First, students toss coins to determine what traits a set of mouse parents possesses, such as fur color, body size, heat tolerance, and running speed. Next they use coin tossing to determine the traits a mouse pup born to these parents possesses. These physical features are then compared to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?

In this art history video discussion Beth Harris and Steven Zucker consider Michael Pacher's "Saint Wolfgang Altarpiece," 1471-81, polychrome pine, linden, gilding, and oil (sculpture and painting). Parish Church, Sankt Wolfgang, Austria.

This art history video discussion looks at Michelangelo's Ceiling of the Sistine Chapel, 1508-12 (Vatican, Rome).

This art history video discussion examines Michelangelo's "Last Judgment" Sistine Chapel Ceiling, fresco, 1534-1541 (Vatican City, Rome).

This art history video discussion examines Michelangelo's "Moses", marble, ca. 1513-15 (San Pietro in Vincoli, Rome).

This art history video discussion examines Michelangelo's "Pieta", marble, 1498-1500 (Saint Peter's Basilica, Rome).

This art history video discussion examines Michelangelo's "The Slaves" (commonly referred to as the Dying Slave and the Rebellious Slave), marble, 2.09 m high, 1513-15 (Musee du Louvre, Paris).

Students design systems that use microbes to break down a water pollutant (in this case, sugar). They explore how temperature affects the rate of pollutant decomposition.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.
