PS Physical Sciences
- 8.PS1.1Particles, Atoms, Elements, and CompoundsUse a model to understand that atoms are a system composed of a positively charged nucleus surrounded by one or more negatively charged particles called electrons
- 8.PS1.2Particles, Atoms, Elements, and CompoundsDevelop a model to explain how the light coming from distant stars and the formation of heavier atoms is the result of changes in the composition of the nucleus of the atom and the energy released during the process of nuclear fusion
- 8.PS2.1Forces, Motion, and InteractionsConduct an investigation to provide evidence that the size of force fields (electric and magnetic) depends on the magnitudes of the charges, current, or magnetic strengths involved and the distances between interacting objects
- 8.PS2.2Magnets, Electricity, and CircuitsAsk scientific questions about data to determine how manipulating variables can increase or diminish the electric current and magnetic field strength in electromagnets, generators, and electric motors
- 8.PS2.3Gravity and Object MotionConstruct an argument using evidence to support the claim that gravitational interactions in a large-scale system are attractive and depend on the masses of and distance between interacting objects
- 8.PS2.4Forces, Motion, and InteractionsConstruct an explanation to describe why the position and motion of object(s) in a system, and the effects of forces on those objects, vary with respect to the observer
- 8.PS2.5Forces, Motion, and InteractionsPlan and conduct 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.PS2.6Forces, Motion, and InteractionsEvaluate and interpret that for every force exerted on an object there is an equal force exerted in the opposite direction
- 8.PS4.1Material Properties and UsesDevelop and use models to represent the basic properties of waves in a system including frequency, amplitude, wavelength, and speed
- 8.PS4.2Magnets, Electricity, and CircuitsConstruct explanations from observed patterns of wave behaviors to compare and contrast mechanical waves and electromagnetic waves based on refraction, reflection, transmission, absorption, and their behavior through a vacuum and/or various media
- 8.PS4.3Engage Argument Evidence Claim Digitized Signals Sent WaveEngage in argument from evidence to support the claim that digitized signals, sent as wave pulses, are more reliable than analog signals to transmit information in a system

- 8.LS4.3Cells, Body Systems, and GeneticsConstruct an explanation based on evidence that explains how genetic variations of traits in a population increase some individuals' probability of surviving and reproducing
- 8.LS4.4Adaptation, Biodiversity, and Natural SelectionDevelop a scientific explanation of how natural selection plays a role in determining the survival and reproduction of a species in a changing environment
- 8.LS4.5Organism Needs, Structures, and Life CyclesObtain, evaluate, and communicate information about the technologies that have changed the way humans use artificial selection to influence the inheritance of desired traits in other organisms

- 8.ESS2.2Data Collected Seismographs Earth'S Structure Energy Derived Earth'SEvaluate data collected from seismographs to create a model of Earth's structure and to understand how energy is derived from Earth's hot interior
- 8.ESS2.3Evidence Energy Earth'S Interior Drives Convection Cycles WithinGather and evaluate evidence that energy from the earth's interior drives convection cycles within the asthenosphere which creates changes within the lithosphere including plate movements, plate boundaries, and sea-floor spreading
