We will be covering the Tigard-Tualatin School District Standards for 8th Grade Science this year. As we work through the standards, please bear in mind that many of the standards are interconnected. Just as the many facets of our lives are interwoven, so are the standards. Practice related to one standard may appear in multiple units of study. Look for material from the various standards throughout the school year!
- TTSD District Priority/Power Standards (State Standards) are indicated in grey.
- Supporting Standards (State Standards) are indicated in green.
Physics & Chemistry
- Apply the laws of motion and gravitation to describe the interaction of forces acting on an object and the resultant motion. (H.2P.4)
- Identify and describe types of motion and forces and relate forces qualitatively to the laws of motion and gravitation. (7.2P.1)
- Explain how energy is transferred, transformed, and conserved. (8.2P.2)
- Describe the atomic model and explain how the types and arrangements of atoms determine the physical and chemical properties of elements and compounds. (8.1P.1)
- Explain how the Periodic Table is an organization of elements based on their physical and chemical properties. (8.1P.2)
- Compare and contrast physical and chemical changes and describe how the law of conservation of mass applies to these changes. (8.2P.1)
Astronomy
- Explain how gravity is the force that keeps objects in the solar system in regular and predictable motion and describe the resulting phenomena. Explain the interactions that result in Earth’s seasons. (8.2E.1)
- Classify the bodies in our solar system based on properties and composition. Describe attributes of our galaxy and evidence for multiple galaxies in the universe. (H.1E.)
- Describe the properties of objects in the solar system. Describe and compare the position of the sun within the solar system, galaxy, and universe. (6.1E.2)
- Describe how the universe, galaxies, stars, and planets evolve over time. (H.2E.3)
Earth Science: Plate Tectonics
- Identify and predict the effect of energy sources, physical forces, and transfer processes that occur in the Earth system. Describe how matter and energy are cycled between system components over time. (H.2E.1)
- Explain how landforms change over time at various rates in terms of constructive and destructive forces. (7.2E.4)
- Describe the processes of Earth’s geosphere and the resulting major geological events. (8.2E.2)
- Analyze evidence for geologic and climatic changes over time. (8.2E.4) {Other portions of this standard are taught in 7th grade.}
- Describe the structure and composition of Earth’s atmosphere, geosphere, and hydrosphere. (H.1E.2)
Earth Science: Climate
- Analyze evidence for geologic and climatic changes over time. (8.2E.4) {Other portions of this standard are taught in 7th grade.}
- Describe the composition of Earth’s atmosphere, how it has changed over time, and implications for the future. (7.2E.2)
- Describe the structure and composition of Earth’s atmosphere, geosphere, and hydrosphere. (H.1E.2)
- Explain how Earth’s atmosphere, geosphere, and hydrosphere change over time and at varying rates. Explain techniques used to elucidate the history of events on Earth. (H.2E.2)
- Explain the causes of patterns of atmospheric and oceanic movement and the effects on weather and climate. (8.2E.3)
Scientific Method
- Based on observations and science principles propose questions or hypotheses that can be examined through scientific investigation. Design and conduct a scientific investigation that uses appropriate tools, techniques, independent and dependent variables, and controls to collect relevant data. (8.3S.1)
- Organize, display, and analyze relevant data, construct an evidence-based explanation of the results of a scientific investigation, and communicate the conclusions including possible sources of error. Suggest new investigations based on analysis of results. (8.3S.2)
- Explain how scientific explanations and theories evolve as new information becomes available. (8.3S.3)
Engineering Design
- Define a problem that addresses a need, and using relevant science principles investigate possible solutions given specified criteria, constraints, priorities, and trade-offs. (8.4D.1)
- Design, construct, and test a proposed engineering design solution and collect relevant data. Evaluate a proposed design solution in terms of design and performance criteria, constraints, priorities, and trade- offs. Identify possible design improvements. (8.4D.2)
- Explain how creating a new technology requires considering societal goals, costs, priorities, and trade- offs. (8.4D.3)
