Discovering Biological Science II (2018 Update)
Second EditionJohn S. Peters; Brian R. Scholtens©2018
Learn to appreciate the collaborative, creative, and dynamic nature of science through the many inquiry-based lab experiments in Discovering Biological Science II (2018 Update). Labs revolve around issues relevant to college students today and are fueled by learning theory and the scientific process of discovery. Use the series of labs in this text to gain a better understanding of biology.
Table of Contents
2. Exploring the Evolutionary Genetics of Sickle Cell Alleles—This uses the popular SimBio® Sickle Cell Alleles computer simulation software. The lab contextualizes abstract evolutionary genetics concepts to a classic case of how malaria influences the prevalence of sickle cell anemia in humans. The student instructions for this lab have been modified in DBS I to make this exploration more inquiry based.
3. Adaptations: Thermoregulation in Butterflies—This lab has students constructing models of butterflies to test alternative hypotheses regarding thermoregulatory adaptations.
4. Exploring Water and Nutrient Transport in Plants—Students test their own hypotheses about how environmental factors might affect transpiration rate in stem and leaf cuttings.
5. Exploring Animal Circulation I—This lab had students initially making careful observations of mammalian heart structure. Students then pose hypotheses about heart how the heart pumps blood, which they then test by measuring the heart’s electrical activity (EKG), heart sounds, and pressure during the heart cycle.
6. Exploring Animal Circulation II—This second part of the Animal Circulation lab has students using computer-based dissections to explore circulation in several vertebrate groups.
7. Exploring a Scientific Journal Article—This lab helps students develop the skills necessary to interpret and evaluate a scientific paper, which will, in turn, guide them in generating their own relevant biological questions.
8. Independent Team Projects Labs—This lab has teams honing their scientific process skills by conceiving of, developing, and executing an investigation of their own design. Compared to the independent projects lab we developed in DBS I, this lab affords students more flexibility in terms of the topic they are interested in exploring as students can explore questions related to prior lab explorations.
9. Exploring Human Overpopulation and Environmental Sustainability—This lab begins with a case study in which the issue of human overpopulation of the planet is presented as a myth. After initially reflecting on their views, students calculate their current and future ecological footprint and discuss its implications for sustainability.
