This Immersion Unit provides a coherent series of lessons designed to guide students in developing deep conceptual understanding that is aligned with the standards, key science concepts, and essential features of classroom inquiry (as defined by the National Science Education Standards). Unit Overarching Concepts-Populations of living organisms change or stay the same over time as a result of the interactions between the genetic variations that are expressed by the individuals in the populations and the environment in which the population lives.-Science knowledge advances through inquiry.Unit Supporting Concepts-Individual organisms with certain variations of traits (adaptations) are more likely than others to survive and reproduce successfully.-When environmental conditions change it can affect the survival of both individual organisms and entire species.-Natural selection determines the differential survival of groups of organisms.-A small advantage in escaping a predator, resisting a drug, etc. can lead to the spread of a trait in a modest number of generations.-Mutations are a source of variation in an individualĺŐs genotype, and it can result in a change in phenotypeĺĐĺĐgood or bad.-Scientific progress is made by asking meaningful questions and conducting careful investigations, using appropriate tools and technology to perform tests, collect data, analyze relationships, and display data.-No matter how well one scientific explanation fits observations, a new explanation might fit them just as well or better, or might fit a wider range of observations. In science, thetesting, revising, and occasional discarding of explanations, new and old, never ends.This unit was developed through the large Math and Science Partnership project called System-wide Change for All Learners and Educators (SCALE), involving a collaboration among Los Angeles School District educators, California State University science and education faculty, and UW-Madison SCALE staff.

This Immersion Unit provides a coherent series of lessons designed to guide students in developing deep conceptual understanding that is aligned with the standards, key science concepts, and essential features of classroom inquiry (as defined by the National Science Education Standards). The Unit's overarching concepts are:- Naturally occurring variations of traits in a population are influenced by genetic and environmental factors and evolve over generations by selective processes.- Science knowledge advances through inquiry.Unit Supporting Concepts:- The variation of organisms within a species increases the likelihood that at least some members of the species will survive under changed environmental conditions.- Individual organisms with certain traits are more likely than others to survive and have offspring. Changes in environmental conditions can affect the survival of individual organisms and entire species.- Some variation in heritable characteristics exists within every species. One of these characteristics gives individuals an advantage over others in surviving and reproducing, and the advantaged offspring, in turn,are more likely than others to survive and reproduce.- New varieties of cultivated plants and domestic animals have resulted from selective breeding for particular traits.- Scientists differ greatly in whatphenomena they study and how they go about their work. Although there is nofixed set of steps that all scientists follow, scientific investigations usually involve the collection of relevant evidence, the use of logical reasoning, and the application of imagination in devising hypotheses and explanations to make sense of the collected evidence.- Important contributions to the advancement of science, mathematics, and technology have been made by different kinds of people, in different cultures, at different times.In Immersion Units, students learn academic content by working like scientists: making observations, asking questions, doing further investigations to explore and explain natural phenomena, and communicating results based on evidence. Immersion Units are intended to support teachers in building a learning culture in their classrooms to sustain studentsĺŐ enthusiasm for engaging in scientific habits of thinking while learning rigorous science content.The first step of this unit engages students in developing a class criteria for effective record-keeping in science by guiding an inquiry into scientists' notebooks.The unit includes very complete implementation instructions (Teacher's Guide pages), student pages, and formative and summative assessments.Students investigate:- how variation within a population is influenced by environmental factors- how environmental factors influence reproductive success in a populationThis unit was developed through the large Math and Science Partnership project called System-wide Change for All Learners and Educators (SCALE), involving a collaboration among Los Angeles School District educators, California State University science and education faculty, and UW-Madison SCALE staff.

The genes present in the DNA of a chromosome help to explain the genotypic and phenotypic differences seen in organisms of the same species i.e. Fugate Family. The genes code for specific proteins and these proteins can be varied during meiosis when parents (½ from each parent) are passing their genetic information to their offspring. This passing of genetic information can be predicted and traced through many generations, due to the principles of Mendelian Genetics, and can be useful when determining the starting point of a phenotype. The environment a particular species inhabits may help to explain why some genes become favorable, as small isolated populations often have connections to inbreeding (incest).
