Heredity Cross Walk
Concepts: Looking at Natural Selection; NGSS bundle includes HS-LS3-1;3-2;3-3;HS-LS4-2;4-3
Concept 1 : Central Dogma and Chromosomes (HS-LS3-1)
LS1.A Structure and Function
All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins.
LS3.A inheritance of Traits
Each chromosome consists of a single very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA ... Not all DNA codes for a protein; some segments of DNA are involved in regulatory of structural functions, and some have no as-yet known function.
Skills: Asking the question using think-pair-share or sit-stand-speak, to construct a model based on their prior knowledge
Product: Students will create a final diagram of central dogma to be able to use the DNA of lactase persistence gene to create the protein of lactase.
Crosscutting Concepts: Cause and Effect
Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects
Level Lesson Phenomena
Got Milk?
Science and Engineering Practice
Asking Questions and Defining Problems
Asking questions and defining problems in 9-12 builds on K-8 experiences and progresses to formulating, refining and evaluating empirically testable questions and design problems using models and simulations.
Concept 2: Mutations (HS-LS3-2)
LS3.B Variation of Traits
In sexual reproduction, chromosomes can sometimes swap sections during the process of meiosis (cell division), thereby creating new genetic combinations and thus more genetic variations ... Environmental factors can also cause mutations in genes, and viable mutations are inherited.
Concept 3: Statistics Analysis (HS-LS3-3)
LS3.B Variation of Traits
Environmental factors also affect expression of traits, and hence affect the probability of occurrences of traits in a population. Thus, the variation and distribution of traits observed depends on both genetic and environmental factors
Concept 4: Four Factors of Evolution (HS-LS4-2)
Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
Skill: Experimenting Inquiry
Students will investigate past studies that provide support for an organisms with an advantageous heritable trait.
Product: Summative Assessment Students will use their research from lesson four to create a poster and present their findings. Their poster will also contain their predictions that answer four different "what if" questions.
Science and Engineering Practice: Analyzing and Interpreting Data
Analyzing data 9-12 builds on K-8 experiences and progresses to introducing more detailed statistical analysis, the comparison of data sets for consistency, and the use of models to generate and analyze data.
Level Lesson Phenomena
Will finches survive?
Crosscutting Concepts: Patterns
Different patterns may be observed at each of the scales at which a system is studied and can provide evidence for causality in explanations of phenomena
Skills: Analyzing and Interpreting Data
Students will compare and analyze a variety of data sets that have been recorded in the last 40 years.
Product: 3- Minutes Presentation/Notebook Completion
Students will write in their notebooks, collecting information on their species of finches assigned to them. Students will be able to predict how beaks vary between finches.
Crosscutting Concepts: Scale, Proportion and Quantity
Algebraic thinking is used to examine scientific data and predict the effect of a change in one variable on another (e.g., linear growth vs. exponential growth).
Level Lesson Phenomena
How does the environment affect beak form??
**Science and Engineering Practice: Analyzing and Interpreting Data
Analyzing data in 9-12 builds on K-8 experiences and progresses to introducing more detailed statistical analysis, the comparison of data sets for consistency, and the use of models to generate and analyze
Skills: Experimenting using inquiry. Students will tie back to knowledge of DNA and chromosomes to compare how mutations and environmental factors may effect traits found in a population
Product: Students will be able to describe the relationship between variations and mutations
Science and Engineering Practices: Engaging in Argument from Evidence
Make and defend a claim based on evidence about the natural world the reflects scientific knowledge and student-generated evidence
Level Lesson Phenomena
We May Vary.
Crosscutting Concepts: Cause and Effect
Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects
Anchoring Phenomena
Prediction of the survival rate of Finches in the next fifty years.

Galapagos Finches : A parasite
Philornis downsi
(lays eggs in finch nests).
A group of students took a trip to see Darwin’s finches. They noticed many of the finches' nests were empty and tagged. Unsure of what was happening, the professor came across an article from the Smithsonian magazine. Students wanted to know which finches were being affected. The professor pulled up a phylogenetic tree of the finches and was able to show the students which groups were being most affected as they continued their trip around the island. Back in their hotel, students were still in debate as to whether this could be it for the Galapagos finches. The professor was able to find a video that connected all the information scientists were able to collect on the current issue. Students will decide whether this is important and affecting our lives as we give them a new fact. They will stand in a respected corner no, yes, and I do not know.
1st : Will finches go extinct?
2nd: Two groups not affected?
3rd: Not all finches have high morality
