1.00 Credits
The functions of the human body are studied, and investigative experiences are emphasized. Necessary biology and chemistry background are presented, and the principles of data collection and analysis are stressed. Exercise, muscle, nerve, digestive, and respiratory physiology are among the topics studied. Electroencephalography is a technique used to gather data. This course is designed to satisfy a science laboratory requirement and may not be used to satisfy major or minor requirements in any of the sciences. Prerequisite: BIOL 101 and BIOL 107. Corequisite: BIOL 102. 3 laboratory hours weekly. 1 semester hour

6.00 Credits
This writing-enriched course for nonscience majors is designed to fulfill the lab science distribution requirement. The goals of the class are (1) to empower students (our future citizenry) to make informed decisions (2) by helping students to acquire the tools of gathering information (research), decision making, and persuasion. The class is centered on four topics: evolution, environmental pollution, biotechnology, and human populations and reproductive health. We encourage students to become engaged in issues regarding all four topics by assigning "action papers."These action papers are letters sent to people in profit and nonprofit organizations and government agencies, and to politicians and other individuals in positions to take action on any of these matters. The letters request information, prompt certain actions, or express an opinion regarding a specific policy based on sound understanding of the science involved. Small inquiry groups conduct web-based research on these topics and present their findings in oral presentations/discussions to the class community. Each inquiry group and individual student writes a paper on each of the four topics. Course assessment is based on these assignments. 6 hours of lecture and laboratory. 4 semester hours

3.00 Credits
A course designed to introduce students to the important role microorganisms play in our daily lives. Topics include the structural and functional diversity of microorganisms, the history of microbiology, and the importance of microorganisms in medicine, industry, food and dairy products, and the environment. Three hours lecture. Designed as a science elective for business, humanities, and social science students. 3 hours weekly. 3 semester hours
-
3.00 Credits
An introduction to the diversity and uses of the plant kingdom and related organisms. The interdependence of plant and animal communities and the importance of plants and their products to the health and development of human society are discussed. Topics include classification; economically important plants-foods, medicines and drugs, building materials, ornamentals, etc.; native flora of the major biomes; and plant conservation. Several mandatory field trips are taken to local botanical gardens and natural areas as part of the laboratory component. This course is designed to satisfy a science laboratory requirement for nonscience majors and cannot be used to fulfill requirements for any major or minor in science. 3 lecture hours. 3 laboratory hours. 4 semester hours
-
3.00 Credits
An introduction to the science of nutrition. Human nutrient requirements, nutrient absorption, malnutrition (overconsumption as well as underconsumption), recommended dietary guidelines, and topics of current interest are covered. Special attention is paid to helping the student evaluate his/her own nutrition practices. Designed as a science elective for nonscience majors. 3 hours lecture. 3 semester hours
-
4.00 Credits
This is an integrated lecture/laboratory course. The principal animal used for dissection is the cat. Fundamental principles of biological systems are presented in the context of human anatomy and physiology. The cell as the fundamental unit of life is discussed and examined, including structure and metabolism. The organization of cells into tissues, tissues into organs, and organs into systems is thoroughly explored, and the integumentary, skeletal, muscular, and nervous systems are focal points of study. The somatic and special senses are examined, and the basic principles of endocrine and prostaglandin physiology are introduced. This course does not satisfy any biology or science elective requirements for a biology major. Prerequisite: CHEM 105–106 or CHEM 101–103. Corequisite: CHEM 102–104. 3 class hours and3 laboratory hours weekly. 4 semester hours
-
4.00 Credits
This course is a continuation of BIOL 121. The course examines the structure and function of seven organ systems: (1) endocrine system, (2) cardiovascular system, (3) lymphatic and immune system, (4) respiratory system, (5) digestive system, (6) urinary system, (7) reproductive system and inheritance. The course emphasizes structure and function relationships as well as the interaction among the organ systems. Many of the laboratory exercises involve the use of computerized data acquisition and computerized data analyses. This course does not satisfy any biology or science elective requirements for a biology major. Prerequisite: BIOL 121. 3 class hours and 3 laboratory hours weekly. 4 semester hours
-
3.00 Credits
This course is intended for biology majors and premedical students. The course, the first of the core curriculum, will center on evolution as the organizing principle of living systems which will form the framework for the problems and processes considered in courses II and III that follow. This course begins with Unit (1) Elements of Living Organisms, which will explore the biological, physical, and chemical principles that govern a living organism. The context in which these principles will be explored is the evolutionary origin of life on Earth. Unit (2) Biological Evolution will continue this evolutionary theme and will focus upon genetic mechanisms of inheritance and the resulting microand macroevolutionary processes. Unit (3) Ecological Systems of Life, will elucidate organizational principles by which groups of interacting individuals form populations, ecological communities, and ecosystems. Contextual themes for this unit include the ecological significance of biodiversity, conservation ecology, and the global ecosystem consequences of our 6+ billion human population. 3 hours lecture. 3 hours laboratory. 1 hour discussion. 4 semester hours

4.00 Credits
This course is intended for biology majors and premedical students. The course thoroughly explores the structure and function of the major organ systems of plants and animals and examines the diversity of solutions to ecological problems that these taxa have evolved. This course also explores the major evolutionary trends underlying the variation in (organ) systems’ structure and function and their integration and coordination along lineages of evolving animals and plants. Prerequisite: BIOL 161 and CHEM 145 or permission of instructor. 3 hours lecture. 3 hours laboratory. 1 hour discussion. 4 semester hours

3.00 Credits
Students travel to Smedley Middle School and offer life science enrichment education sessions for 6th, 7th, and 8th graders as part of an ongoing after school enrichment education program by the Chester Education Foundation. The goals and content of these enrichment sessions are closely aligned with ongoing middle school curricula in these classrooms, and are based on the content areas of the freshman major's curricula in biology at Widener (ecology, evolution, and plant and animal structure and function [BIOL 161 and 162]). These science enrichment sessions constitute "experiential service learning" for students.Prerequisite: BIOL 161. Pre- or corequisite: BIOL 162, or permission of the instructor. 3 hours classroom/lab time per week. 3 semester hours
