Reflection: Adjustments to Practice Using Simulations to Discuss Basic Concepts in Evolution - Section 5: The Classroom Flow: Working with Simulation #3 (Hawks, Birds, and Insects)

 

One of the best parts of teaching evolution is that it is not simply a topic of biology; it is a theme that runs throughout every concept in biology and something that students can use as a unifying theme throughout their studies.  One of the easiest connections to make is the one between evolution and ecology.  For example, Whittaker's classification system is based upon ecological relationships.  Natural selection takes its name from the idea that unique environments at specific times in history favor specific variations found within a population and that as the environment shifts, so do the adaptations.  

Both evolution and ecology are things that students can visually see and relate to, unlike DNA or cells in general.  This shift from the micro- view first semester to the macro- view second semester provides many opportunities to bring in what students remember from our previous units, specifically in DNA, protein synthesis, and genetics and put it together with their prior knowledge from their study of and personal interactions with the natural world.  Because of that, today's lesson is one in which you can bring in a lot of accessory ideas that you will work with in more detail in the next unit.  Students will be ready for it and proud of themselves for their new found ability to see the connections between these two subjects on the screen as well as in their own minds.
