This set of 10 questions gives students just enough information to solve for p (dominant allele frequency) and q (recessive allele frequency), and often asks them to calculate the percentage of heterozygous individuals (2pq). This worksheet was designed for an AP Biology class and was revised April 2019. There is an older version that has many of the answers posted online, so this one has been changed slightly so that students cannot easily find the answers and take a shortcut. The ten problems ]]> 0 Evolution – VIDA chart Fri, 19 Apr 2019 20:06:46 +0000 This chart is used as a graphic organizer to help students understand the process of evolution by natural selection. I use this chart multiple times throughout the unit, basically for each model organism we study. VIDA means: Variation, Inheritance, Differential Survival and Reproduction, Adaptation. These principles apply not matter what organism you are studying. For example, if you start with the finches of the Galapagos, Variation refers to birds having different sized beaks. Inheritance means that this trait is something that can be inherited or that it is genetic. Differential survival and reproduction means that some birds were better able ]]> 0 Reinforcement: Evolution Thu, 18 Apr 2019 17:55:34 +0000 This worksheet was designed for an introductory biology class where students are exposed to basic concepts of biology. The unit covers the history of evolutionary thought (Darwin and the finches of the Galapagos) but focuses more on modern examples of evolution. Students match a description or definition to a list of words. The main focus of this activity is to practice the vocabulary learned during the lessons, concepts like variation, natural selection, inheritance, adaptation. The final section of the activity asks students to summarize how evolution occurred in model organisms we studied in class: rock pocket mice, African elephants, and ]]> 0
