Unit 2: NATURAL SELECTION

LP 2.1
- I can analyze patterns in population data to make a claim about how the variation of traits in a population changes over time.

LP 2.2
- I can use patterns in data as evidence to revise a scientific model about how the struggle to survive within population leads to a change in the frequency of traits in a population.

LP2.3
- I can use carious forms of data as evidence to support a claim that explains the cause and effect relationship between variation of traits in a population and the survival of the fittest.

LP 2.4
- I can construct appropriate graphical models to identify the patterns in the evolution of traits in a population over time.

STUDENTS WILL:

EXPLORE THE FOLLOWING SCIENCE AND ENGINEERING PRACTICES:

- Analyzing and interpreting data.
- Constructing explanations and designing solutions.

HAVE DISCOURSE ON THE FOLLOWING DISCIPLINARY CORE IDEAS:

LS4.B: Natural Selection
Natural selection occurs only if there is both (1) variation in the genetic information between organisms in a population and (2) variation in the expression of that genetic information—that is, trait variation—that leads to differences in performance among individuals.

LS4.C: Adaptation
Evolution is a consequence of the interaction of four factors: (1) the potential for a species to increase in number, (2) the genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for an environment’s limited supply of the resources that individuals need in order to survive and reproduce, and (4) the ensuing proliferation of those organisms that are better able to survive and reproduce in that environment.

LS4.D: Biodiversity and Humans
Humans depend on the living world for the resources and other benefits provided by biodiversity. But human activity is also having adverse impacts on biodiversity through overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and climate change. Thus sustaining biodiversity so that ecosystem functioning and productivity are maintained is essential to supporting and enhancing life on Earth. Sustaining biodiversity also aids humanity by preserving landscapes of recreational or inspirational value. (HS-LS4-6) (Note: This Disciplinary Core Idea is also addressed by HS-LS2-7.)


OBSERVE THE FOLLOWING CROSS CUTTING CONCEPTS:

- PATTERNS
- CAUSE AND EFFECT

GS 3a:  MODELING - Students can construct and use models to represent and analyze phenomena and systems.

GS 4a:  Data analysis and interpretation - Students can analyze and interpret scientific data and solve problems using a range of tools, technology and mathematical techniques.

GS 5a, b:  Explanation and argumentation - Students can develop, evaluate, and critique scientific claims/ explanations, arguments and solutions based on evidence from the natural and designed world.
