Synopsis

Anchored Science by Mi-STAR is a middle school science curriculum motivated by a vision for the future in which science is taught and learned as an integrated body of knowledge that is applied to address societal issues. The curriculum incorporates all the best that the Next Generation Science Standards have to offer, while empowering students to use science and engineering practices to address real-world issues. Unit 8.1: Adaptation and Natural Selection, Bugs in the Bed!? In this unit, students discover how a species can survive a change in the environment through the processes of natural selection and adaptation. Students use models and mathematical representations to support their explanation for how the traits of a population of organisms can change over time in order to adapt to a change in their environment. The Unit Challenge uses bed bug resistance to insecticide as the context to explore these processes in action in a real-life scenario. Students first learn that traits in a population can have different effects on organisms depending on the environmental conditions present, and those traits can affect some individuals’ probability of surviving and reproducing. Then students examine how different traits can occur in a population, first building on prior knowledge from Unit 7.6 about sexual reproduction and then examining another cause - genetic mutations - and their effect on the structure and function of an organism’s proteins. Students apply these concepts over large timescales to explain how natural selection can affect the distribution of traits in a population over time, causing the population or species to adapt to the change in the environment.
