= Learning Experience 12: Genetics and Evolution: Making the Connection =


 * Objectives **
 * Students develop a definition of evolution
 * Students simulate selective pressure on population and use their data to explain changes in genes and traits
 * Students define the relationship between genetic variation and evolution


 * Driving Questions **
 * How do kinds of living things change, when encountering the struggle for survival in the environment
 * What happens to genetic variation from generation to generation?


 * // Teddy Graham Selection //**
 * //For each group://**
 * 1 small plastic reclosable bag
 * 10 Teddy Grahams (a mixture of chocolate and honey) or colored Gold Fish crackers
 * Students model natural selection by predation using Teddy Graham crackers Procedure p. 293
 * Record results in a Data Table
 * Graph results for each generation


 * Processing for Meaning **
 * Present data and discuss the implications in terms of natural selection (we will omit the discussion of a gene pool but return to this topic in the Genetics unit)
