The Organismal Biology 1108: Laboratory Manual provides students with hands-on laboratory experiences that explore the diversity of life, biological organization, and the scientific methods used to study living organisms. Beginning with an introduction to biology, statistics, and essential laboratory skills, the manual guides students through the study of prokaryotes, protists, fungi, plants, arthropods, and animal ecology while emphasizing the evolutionary relationships that connect all forms of life. Through inquiry-based investigations and scientific observation, students gain a practical understanding of biological concepts and the processes that shape living systems.
Throughout the manual, students develop laboratory and analytical skills by conducting experiments in microbiology, ecology, genetics, systematics, bioinformatics, and symbiotic relationships. Activities such as chi-square analysis, species identification, ecological investigations, and the use of bioinformatics tools encourage critical thinking, data analysis, and scientific communication. By integrating laboratory techniques with biological theory, the manual prepares students for advanced coursework and careers in biology, environmental science, ecology, healthcare, and other life science disciplines.
