8.P.2A: Motion occurs when there is a change in position of an object with respect to a reference point. The final position of an object is determined by measuring the change in position and direction of the segments along a trip. While the speed of the object may vary during the total time it is moving, the average speed is the result of the total distance divided by the total time taken. Forces acting on an object can be balanced or unbalanced. Varying the amount of force or mass will affect the motion of an object. Inertia is the tendency of objects to resist any change in motion.
8.P.2A.1: Plan and conduct controlled scientific investigations to test how varying the amount of force or mass of an object affects the motion (speed and direction), shape, or orientation of an object.
8.P.2A.2: Develop and use models to compare and predict the resulting effect of balanced and unbalanced forces on an object's motion in terms of magnitude and direction.
8.P.2A.3: Construct explanations for the relationship between the mass of an object and the concept of inertia (Newton's First Law of Motion).
8.P.2A.4: Analyze and interpret data to support claims that for every force exerted on an object there is an equal force exerted in the opposite direction (Newton's Third Law of Motion).
8.P.2A.5: Analyze and interpret data to describe and predict the effects of forces (including gravitational and friction) on the speed and direction of an object.
8.P.2A.6: Use mathematical and computational thinking to generate graphs that represent the motion of an object's position and speed as a function of time.
8.P.2A.7: Use mathematical and computational thinking to describe the relationship between the speed and velocity (including positive and negative expression of direction) of an object in determining average speed (v=d/t).
8.P.3A: Waves (including sound and seismic waves, waves on water, and light waves) have energy and transfer energy when they interact with matter. Waves are a repeating pattern of motion that transfers energy from place to place without overall displacement of matter. All types of waves have some features in common. When waves interact, they superimpose up on or interfere with each other resulting in changes to the amplitude. Major modern technologies are based on waves and their interactions with matter.
8.P.3A.2: Develop and use models to exemplify the basic properties of waves (including frequency, amplitude, wavelength, and speed).
8.P.3A.3: Analyze and interpret data to describe the behavior of waves (including refraction, reflection, transmission, and absorption) as they interact with various materials.
8.P.3A.4: Analyze and interpret data to describe the behavior of mechanical waves as they intersect.
8.P.3A.5: Construct explanations for how humans see color as a result of the transmission, absorption, and reflection of light waves by various materials.
8.P.3A.6: Obtain and communicate information about how various instruments are used to extend human senses by transmitting and detecting waves (such as radio, television, cell phones, and wireless computer networks) to exemplify how technological advancements and designs meet human needs.
8.E.4B: Earth's solar system consists of the Sun and other objects that are held in orbit around the Sun by its gravitational pull on them. Motions within the Earth-Moon-Sun system have effects that can be observed on Earth.

8.E.4B.2: Construct explanations for how gravity affects the motion of objects in the solar system and tides on Earth.
8.E.4B.3: Develop and use models to explain how seasons, caused by the tilt of Earth's axis as it orbits the Sun, affects the length of the day and the amount of heating on Earth's surface.
8.E.4B.4: Develop and use models to explain how motions within the Sun-Earth-Moon system cause Earth phenomena (including day and year, moon phases, solar and lunar eclipses, and tides).
8.E.4B.5: Obtain and communicate information to describe how data from technologies (including telescopes, spectroscopes, satellites, space probes) provide information about objects in the solar system and the universe.
8.E.5A: All Earth processes are the result of energy flowing and matter cycling within and among Earth's systems. Because Earth's processes are dynamic and interactive in nature, the surface of Earth is constantly changing. Earth's hot interior is a main source of energy that drives the cycling and moving of materials. Plate tectonics is the unifying theory that explains the past and current crustal movements at the Earth's surface. This theory provides a framework for understanding geological history.
8.E.5A.2: Use the rock cycle model to describe the relationship between the processes and forces that create igneous, sedimentary, and metamorphic rocks.
8.E.5A.4: Construct explanations for how the theory of plate tectonics accounts for
8.E.5A.4.1: the motion of lithospheric plates,
8.E.5A.4.2: the geologic activities at plate boundaries, and
8.E.5A.4.3: the changes in landform areas over geologic time.
8.E.5A.5: Construct and analyze scientific arguments to support claims that plat e tectonics accounts for
8.E.5A.5.1: the distribution of fossils on different continents,
8.E.5A.5.2: the occurrence of earthquakes, and
8.E.5A.5.3: continental and ocean floor features (including mountains, volcanoes, faults and trenches).
8.E.5B: Natural processes can cause sudden or gradual changes to Earth's systems. Some may adversely affect humans such as volcanic eruptions or earthquakes. Mapping the history of natural hazards in a region, combined with an understanding of related geological forecast the locations and likelihoods of future events.
8.E.5B.1: Analyze and interpret data to describe patterns in the location of volcanoes and earthquakes related to tectonic plate boundaries, interactions, and hot spots.
8.E.5B.2: Construct explanations of how forces inside Earth result in earthquakes and volcanoes.
8.E.6A: The geologic time scale interpreted from rock strata provides a way to organize major historical events in Earth's history. Analysis of rock strata and the fossil record, which documents the existence, diversity, extinction, and change of many life forms throughout history, provide only relative dates, not an absolute scale. Changes in life forms are shaped by Earth's varying geological conditions.
8.E.6A.3: Construct explanations from evidence for how catastrophic events (including volcanic activities, earthquakes, climatic changes, and the impact of an asteroid/comet) may have affected the conditions on Earth and the diversity of its life forms.
8.E.6A.4: Construct and analyze scientific arguments to support claims that different types of fossils provide evidence of
8.E.6A.4.1: the diversity of life that has been present on Earth,
8.E.6A.4.2: relationships between past and existing life forms, and
8.E.6B: Adaptation by natural selection acting over generations is one important process by which species change in response to changes in environmental conditions. The resources of biological communities can be used within sustainable limits, but if the ecosystem becomes unbalanced in ways that prevent the sustainable use of resources, then ecosystem degradation and species extinction can occur.
8.E.6B.1: Construct explanations for how biological adaptations and genetic variations of traits in a population enhance the probability of survival in a particular environment.
