8.S.1B.1.1: ask questions to identify problems or needs,
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.3: Construct explanations for the relationship between the mass of an object and the concept of inertia (NewtonÂ?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 (NewtonÂ?s Third Law of Motion).

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.E.5A: All Earth processes are the result of energy flowing and matter cycling within and among EarthÂ?s systems. Because EarthÂ?s processes are dynamic and interactive in nature, the surface of Earth is constantly changing. EarthÂ?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 EarthÂ?s surface. This theory provides a framework for understanding geological history.

8.E.5B: Natural processes can cause sudden or gradual changes to EarthÂ?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.5C: Humans depend upon many Earth resourcesÂ?some renewable over human lifetimes and some nonrenewable or irreplaceable. Resources are distributed unevenly around the planet as a result of past geological processes.
8.E.5C.1: Obtain and communicate information regarding the physical and chemical properties of minerals, ores, and fossil fuels to describe their importance as Earth resources.
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.
