In this simulation, learners become birds different beak types. Learners use various tools to represent beaks to pick up seeds and place them in a petri dish. After completing the activity and collecting data, learners will relate results to adaptations and natural selection. Extensions of the simulation allow for comparative results and include population genetics. Less

This course describes biological changes that happen on a very large scale, across entire populations of organisms and over the course of millions of years, in the form of evolution and ecology. Upon successful completion of this course, students will be able to: Use their understanding of Mendelian genetics and patterns of inheritance to predict genotypes and phenotypes of offspring or work backwards to identify the genotypes and phenotypes of a parental generation; Distinguish between inheritance patterns that involve autosomal vs. sex-linked traits and identify the respective consequences of each type of inheritance; Identify what distinguishes DarwinĺÎĺĺÎĺs theory of evolution from other arguments that attempt to explain diversity across species and/or many generations; Identify which of many types of natural selection is acting on a particular population/species; Identify which of many types of sexual selection is acting on a particular population/species; Identify the factors that alter the frequencies of alleles in populations over time and describe the effects of these factors on populations; Recognize, read, and create phylogenies and cladograms, using them to explain evolutionary relationships; Determine the ecological interactions affecting a particular community and identify the effects of specific relationships (e.g. symbiosis, competition) on species within that community; Distinguish between world biomes in terms of their climate, nutrient cycles, energy flow, and inhabitants; Use their knowledge of nutrient cycles and energy flow to estimate the effect that changes in physical or biological factors would have on a particular ecosystem.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition. In this scenario, learners use M&Ms and other simple materials to investigate the mating habits of beetles and whether genetic variations give male beetles advantages against weaker beetles. Learners will collect and calculate data to draw conclusions. The third part of this activity allows learners to model Hardy-Weinberg and selection using an Excel spreadsheet and is recommended for more advanced learners. Less
