This part of the course is designed to get you up close and personal with many different areas of biology. The formats of the exercises vary greatly, in large part due to the variety of goals we have set for this extremely important component of the course. Here are our main goals: 1. Strengthen your observational skills . It's hard to figure out why something happens the way it does without having a firm grasp of just what it is you are trying to explain! Most of our labs require you to observe biological phenomena. For instance, the lab on microscopes introduces you to the characteristics of very small organisms, whereas the field lab takes you outside to look at larger ones. The evolution, genes and enzymes lab shows you how we must use indirect methods to observe biochemical phenomena that no microscope can reveal. And the dissections in the plant anatomy and the animal morphology labs will let you look beneath the skin of some typical multi-cellular organisms. 2. Reinforce concepts introduced in lecture . All of our labs are directly related to lecture topics. Some biological concepts are hard to understand, however, until you do the hands-on work and physically manipulate the steps of the processes. The scientific method lab, the mitosis/meiosis lab and the population genetics lab are set up to do just that. 3. Learn scientific concepts through independent investigation . Science is the systematic investigation of the world around us, and if you are a curious sort you may be doing science without even knowing it! The majority of our labs are "investigative labs", including the scientific method lab, in which you will design an experiment based on your observations of Daphnia , the energy flow lab, in which you will set up an experiment to see how light levels affect rates of photosynthesis, and the population genetics lab, in which you will study how different factors influence the direction of evolution. 4. Learn biological techniques . Whether you are weighing, measuring, pipetting, dissecting, or learning how to use a dichotomous key, every lab gives you the opportunity to work on some aspect of techniques used in biology. 5. Work with and communicate data . In the course of a scientific investigation, scientists collect data in a specific manner. Recording and organizing data are skills you will work on in this lab. Once collected, you will analyze your data using basic statistical tests, or, where appropriate, make graphs so that you can communicate your results to others. The information will be recorded in your Team Lab Notebook (TLNB). b
