Grade 8 Science 2018 Standards of Learning Test Blueprint

Flashcards based on the Grade 8 Science 2018 Standards of Learning Test Blueprint, defining test structure and key scientific concepts from the curriculum.

Test Blueprint

A guide for test construction that indicates the content areas addressed and the number of items included by content area and for the test as a whole.

Reporting Categories

Groups of Standards of Learning (SOL) that address related content and skills, used to present test scores.

Curriculum Frameworks

Documents that define the essential understandings, knowledge, and skills measured by the Standards of Learning tests.

Operational Items

The $45$ test items used to compute students’ scores on the Grade 8 Science test.

Field-Test Items

The $10$ items administered for potential use on subsequent tests that are not used to compute students’ scores.

Technology-Enhanced Items (TEI)

Items on an online test form that are not multiple-choice, which can make up to $15\%$ of the items.

Force, Motion, Energy, and Matter

A reporting category containing $19$ items covering topics such as energy transformations, atomic structure, water properties, and Newton’s laws.

Living Systems and Ecosystems

A reporting category containing $15$ items covering topics such as watersheds, cell theory, energy transfer, and genetic information.

Earth and Space Systems

A reporting category containing $11$ items covering topics such as the solar system, Earth-sun-moon relationships, and the atmosphere.

Energy Distribution

The process by which radiation, conduction, and convection distribute energy.

Atom

The basic unit of matter consisting of particles including electrons, protons, and neutrons.

Universal Solvent

A term referring to water due to its unique physical properties and role in natural and human-made environments.

Kinetic Molecular Theory

A theory used to predict and explain matter interactions.

Periodic Table

A model used to organize elements based on their atomic structure, classifying them as metals, metalloids, and nonmetals.

Newton’s Laws

Scientific laws used to describe the motion of objects.

Watershed

The land that drains into a body of water.

Chesapeake Bay

An estuary in Virginia that has many important functions and is influenced by natural processes and human activities.

Cell Theory

The theory stating that all living things are composed of one or more cells that support life processes.

Cellular Transport

The process including osmosis and diffusion that is important for life processes.

Photosynthesis

The foundation of virtually all food webs and a chemical process of energy transfer important for life.

Symbiotic Relationships

Interactions in a biological community that support the survival of different species.

Niche

The specific role of an organism that supports its survival within an ecosystem.

Eutrophication

A large-scale change that affects ecosystems, alongside climate changes and catastrophic disturbances.

Punnett Squares

Mathematical models used to predict the probability of traits in offspring.

Evolutionary Evidence

Information provided by the fossil record, genetic information, and anatomical comparisons showing that populations change over time.

Gravity

A force that contributes to orbital motion within the solar system.

Seasons

Phenomena caused by Earth’s tilt as it revolves around the sun.
