7.3D7.11: Organisms & environments. The student knows that populations & species demonstrate variation & inherit many of their unique traits through gradual processes over many generations. The student is expected to:

•7.11C: identify some changes in genetic traits that have occurred over several generations through natural selection & selective breeding such as the Galapagos Medium Ground Finch (Geospiza fortis) or domestic animals.

5TH GRADE

•differentiate between inherited traits of plants and animals such as spines on a cactus or shape of a beak and learned behaviors such as an animal learning tricks or a child riding a bicycle.

7TH GRADE

7.11C: identify some changes in genetic traits that have occurred over several generations through natural selection & selective breeding such as the Galapagos Medium Ground Finch (Geospiza fortis) or domestic animals.

BIOLOGY

•analyze and evaluate how natural selection produces change in populations, not individuals.

•analyze and evaluate how the elements of natural selection, including inherited variation, the potential of a population to produce more offspring than can survive, and a finite supply of environmental resources, result in differential reproductive success.

•analyze and evaluate the relationship of natural selection to adaptation and to the development of diversity in and among species.

• Heredity is the passage of genetic instructions from one generation to the next.

2014 MoY II Question: 7.11C

Based on the data and distractors, what key points should teachers emphasize during lessons?

• Humans selectively breed domesticated animals. Add vocabulary or use of this term as associated with selectively bred organisms.

• Examples of adaptations associated with natural selection.

• Examples of adaptations associated with selective breeding.

Activities to emphasize this point included in the curriculum:

1.BrainPop Video: Natural Selection

2.Natural Selection Activity

3.Natural Selection Card Activity

4.Selective Breeding of Salukis Video

5.A Potpourri of Pooches Reading

6.Natural Selection vs. Selective Breeding Presentation

7.Natural Selection & Selective Breeding Card Sort

• Optional Lessons

Higher level questions• “Research shows there’s a link between critical thinking skills and increased student achievement in the

classroom.” (Moore & Stanley, 2010)

• Higher level questions must be planned in order to be implemented effectively in the classroom.

• Levels of Questions

• Knowledge

• Comprehension

• Application

• Analysis

• Synthesis

• Evaluation

• Plan and provide a variety of questions at each level and build student knowledge and critical thinking by providing Higher Level Questions.

Lower Levels of questions

Knowledge Comprehension Application Analysis Synthesis Evaluate

What are some examples of changes in a

species’ traits that have occurred due

to selective breeding?

What is the difference between natural selection

and selective breeding?

How could variation within a fish

population help individuals survive

their encounter with dolphins?

How do variations within a population or species enhance the survival of the

population or species?

How does historical context help us make informed

decisions?

How do changes in characteristics, structures, and

functions enhance the survival of an

organism and future generations?

How would you improve the

production of corn in corn plants?

•Interactive Word Wall- Current, working models with student contributions • Interactive Word Walls Article: http://learningcenter.nsta.org/files/ss1103_45.pdf

• “Word walls can be arranged on cupboard doors or classroom walls, or hung from the ceiling with wire and string.”

• “Maximum instructional potential and efficiency are achieved when interactive word-wall construction is aligned with lessons and students are allowed to participate in the process. As a result, walls are usually built over many days and are finished as a unit nears completion. Word walls support units and are changed or replaced as units change.”
