2020 Grade 8 Unit Progression Home Page

Page history last edited by Heather Johnston 1 year, 3 months ago

Welcome to the Sample Unit Progressions and corresponding resources for Grade 8. These resources were developed and identified by Oklahoma educators to support instruction aligned to the Oklahoma Academic Standards for Science (OAS-S) and are connected to the Grade 8 Bundled Standards Analyses. Recommendations are not intended to be an exhaustive listing of instructional possibilities.

Check out this Guide to the Sample Unit Progressions for more details about each component in the unit.

Unit Information	Driving Question	Essential Questions	Standards
Unit 1: Forces, Motion, and Interactions (Instructional Resources) Suggested Timeline: 5-6 weeks Forces, Motion, and Interactions Bundle Analysis	How do forces interact with us everyday?	How do forces impact the motion of objects within a system? How is the motion of an object affected by changes in mass or applied force? How can Newton's Third Law be applied to solve a problem? How can an object influence the motion of another object without touching it? How is the strength of an electric or magnetic force affected by different factors?	8.PS2.1 Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects in a system.* 8.PS2.2 Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object. 8.PS2.3 Ask questions about data to determine the factors that affect the strength of electric and magnetic forces. 8.PS2.5 Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

Unit 2: Waves and their Application for Information Transfer (Instructional Resources) Suggested Timeline: 3-5 weeks Waves and their Application for Information Transfer Bundle Analysis	How do waves impact my daily life?	How does a wave model apply to waves we see or hear? How is the structure of a wave related to its energy? How are waves used in communication? Why does modern technology tend to use digital wave signals rather than analog wave signals?	8.PS4.1 Use mathematical representations to describe patterns in a simple model for waves that includes how the amplitude of a wave is related to the energy of a wave. 8.PS4.3 Integrate qualitative scientific and technical information to support the claim that digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information than analog signals.*

Unit 3: Earth's Place in the Universe (Instructional Resources) Suggested Timeline: 5-6 weeks Earth's Place in the Universe Bundle Analysis	How do cyclic patterns in the solar system affect life on Earth?	How can models help describe, predict, and explain patterns of apparent motion for the Sun, Moon, and stars? How can models of the Earth-Sun-Moon system explain eclipses and tides? How can models of the Earth-Sun system explain the seasons? How do similarities and differences in data from Earth-based instruments show scale among objects in the solar system? How does the mass of objects affect their gravitational attraction to other objects in the solar system? How does gravity affect the motions of objects in the solar system and galaxy?	8.PS2.4 Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects. 8.ESS1.1 Develop and use a model of the Earth-Sun-Moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons. 8.ESS1.2 Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system. 8.ESS1.3 Analyze and interpret data to determine scale properties of objects in the solar system.*

Unit 4: Heredity (Instructional Resources) Suggested Timeline: 5-6 weeks Heredity Bundle Analysis	Why do some plants and animals look similar while others look different?	What causes differences within a trait of similar organisms? How do genes affect the structure and function of an organism? How does the type of reproduction affect variation among offspring? How do new variations in genes occur and how does that affect an organism?	8.LS3.1 Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism. 8.LS3.2 Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.

Unit 5: Evidence of Ancestral Relationships (Instructional Resources) Suggested Timeline: 5-6 weeks Evidence of Ancestral Relationships Bundle Analysis	How has life on Earth changed over time?	How can the fossil record be used to document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth? How can anatomical similarities and differences between and among modern and fossilized organisms serve as evidence of ancestral relationships? How can patterns found in embryo development be used to promote evidence for relatedness between adult species?	8.LS4.1 Analyze and interpret data to identify patterns within the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth. 8.LS4.2 Apply scientific ideas to construct an explanation for the patterns of anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer ancestral relationships. 8.LS4.3 Analyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy.

Unit 6: Biological Unity and Diversity (Instructional Resources) Suggested Timeline: 5-7 weeks Biological Unity and Diversity Bundle Analysis	What causes populations to change over time?	How do plant's specialized structures and the characteristic behaviors of animals affect their reproductive success? How is the growth of organisms affected by environmental and genetic factors? How do genetic variation and environmental influences impact an organism's reproductive success and survival? How does natural selection affect the distribution of a specific trait over time within a population? How has the use of artificial selection, by humans, impacted the inheritance of desired traits in organisms?	8.LS1.4 Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively. 8.LS1.5 Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms. 8.LS4.4 Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment. 8.LS4.5 Gather and synthesize information about the practices that have changed the way humans influence the inheritance of desired traits in organisms.* 8.LS4.6 Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.
