Overview: This adaptable instructional module uses insects as a model system to illustrate the biological impacts of climate change, with the goal of engaging students with a range of hands-on and minds-on activities that increase their understanding of how science works, evolutionary processes, and the impacts of climate change. Author/Source: UC Museum of Paleontology Grade level: 13-16 Time: 30 min to 10 class periods Concepts: Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details. Evolution results from natural selection acting upon genetic variation within a population. Natural selection and genetic drift act on the variation that exists in a population. Natural selection acts on phenotype as an expression of genotype. Phenotype is a product of both genotype and the organism’s interactions with the environment. Inherited characteristics affect the likelihood of an organism's survival and reproduction. Over time, the proportion of individuals with advantageous characteristics may increase (and the proportion with disadvantageous characteristics may decrease) due to their likelihood of surviving and reproducing. A hallmark of science is exposing ideas to testing. As with other scientific disciplines, evolutionary biology has applications that factor into everyday life, for example in agriculture, biodiversity and conservation biology, and medicine and health. Scientists use experimental evidence to study evolutionary processes. Teacher background: Natural Selection
