Paul Andersen introduces the concept of ethology and contrasts kinesis and taxis. He explains the importance of courtship rituals in fruit flies. He finally shows you how to use a choice chamber to study behavior in pillbugs.
Paul Andersen shows you how to use a sphygmomanometer to measure the systolic and diastolic blood pressure. The the describes the elements of the laboratory portion. The temperature is gradually lowered and the respiration rate of a goldfish is measured.
Paul Andersen explains the two major portions of the molecular biology lab in AP Biology. He starts by discussing the process of transformation. He explains how you can use the pGLO plasmid to produce glowing E. coli bacteria. He then describes how you can use restriction enzymes and the process of gel electrophoresis to cut and separate DNA.
Paul Andersen explains how pigments can be separated using chromatography. He shows how you can calculate the Rf value for each pigment. He then explains how you can measure the rate of photosynthesis using leaf chads and water containing baking soda.
Paul Andersen compares and contrasts mitosis and meiosis. He shows how you can count cells in various phases of mitosis to construct a cell cycle pie chart. He also explains how you can use the fungus Sordaria to calculate map units using the frequency of cross over.
Paul Andersen starts with a brief description of enzymes and substrates. He then explains how you can measure the rate of an enzyme mediated reaction.
