Topic: Natural Selection and Evolution Part 1 / Performance Expectations:
4 / In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught. / NGSS HS-LS4-1 ,LS4-2
3
Proficient / Students demonstrate they have developed an understanding of:
●Evaluation of multiple lines of empirical evidence to support common ancestry. (vestigial structures, DNA, Amino acid sequences, anatomical and embryological structures, Darwin’s work) [LS4-1]
●Analyzing four factors that lead to evolution [LS4-2]
opotential for a species to increase in number
ogenetic variation due to mutations and sexual reproduction
ocompetition for limited resources
osurvival and reproduction due to adaptation to the environment
●Students demonstrate their understanding of scientific theories, how they are supported by evidence and experimentation, and how they change in light of new evidence. [LS4-1] / Science Practice
●Students construct an explanation that evolution is caused by one or more of the four listed factors. Students must describe the four factors and use reasoning to connect their descriptions to evidence froma variety of valid and reliable sources. [LS4-2]
●(Example of reasoning: genetic variation creates variation of expressed traits in a population, competition for resources occur as a species grows, traits that give competitive advantage increase reproductive success of individuals, over time traits matched to a distinct environment or resource may results in new species) [LS4-2]
●Student can analyze data (charts, graphs, tables) for the distribution of genetic traits over time and describe what each data set represents [LS4-1]
2 / Students will recognize or recall :
Specific vocabulary such as:
common ancestor, homologous structures, evolution, vestigial structures, cladogram
Basic knowledge such as:
●Remembering empirical evidence supporting common ancestry
Understanding the factors that lead to evolution and the effect on a population / Science Practice
- Students communicate evidence for common ancestry and biological evolution using at least two different formats (oral, graphical, textual, and mathematical). Student cite sources appropriately. [LS4-1]
- Students can describe factors that might lead to evolution. [LS4-2]
1 / Student’s performance reflects insufficient progress towards foundational skills and knowledge.
Topic: Natural Selection and Evolution Part 2 / Performance Expectations:
4 / In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught. / NGSS HS-LS3-3 ,LS4-3, LS4-4
3
Proficient / Students demonstrate they have developed an understanding of:
●Application of probability and statistics to support fitness and the processes of evolution [LS3-3, LS4-3]
●Students construct an explanation that identifies the cause and effect relationship between natural selection and adaptation; including:
i. Changes in a population when some feature of the environment changes;
ii. Relative survival rates of organisms with different traits in a specific environment;
iii. The fact that individuals in a species have genetic variation (through mutations and sexual reproduction) that is passed on to their offspring;
iv. The fact that individuals can have specific traits that give them a competitive advantage relative to other individuals in the species.
[LS4-4] / Science Practice
●Students analyze and interpret data to explain the distribution of expressed traits including a description of the expression of a chosen trait and its variations as causative or correlational to some environmental factor based on reliable evidence. [LS3-3]
●Construct an explanation based on evidence for how natural selection leads to adaptation of populations [LS4-4]
●Students construct an explanation that identifies the cause and effect relationship between genetic variation, selection of traits, and the evolution of a population. (Claim, Evidence, Reasoning) [LS4-4]
2 / Students will recognize or recall :
Specific vocabulary such as:
Natural selection, adaptation, artificial selection, fitness
Basic knowledge such as:
●Populations change when the environment changes,
●certain traits impact the survival rates of organisms in a specific environment,
●traits arise from genetic variation and are passed to offspring,
certain traits can give an individual a competitive advantage over other individuals / Science Practice
●[LS4-3]
●Students organize given data by the frequency, distribution, and variation of expressed traits in the population. [LS3-3]
●Given a scenario, student can identify the trait under selection.
Students can describe advantageous adaptations in organisms of their choice.
