Developing and using a model: Students conduct an investigation (Fish in a Pond Investigation) to determine how natural selection can lead to changes in a species over time. In the lab, students make a hypothesis, model the events involved in a genetic cross, identify genotype and phenotype, complete Punnett squares over multiple generations, calculate the probability of each type of offspring, and explore how both genetic and environmental factors play a part in natural selection.
Engaging in argument with evidence: In the LDC module, students select a topic, research, and write a scientific editorial to a Science Scholar Magazine issue entitled: “Genetic Testing and Bio-Engineering: Just because we can, does it mean we should?” In the editorial they need to take a position on what role ethics should play in the field of science they researched.
Engaging in argument with evidence: At the end of the unit, students are hired as a team of lobbyists (an economist, an environmentalist, a farmer, and a doctor) to make a presentation to persuade a government panel to decide whether or not to ban genetically modified foods.
