PS Physical Sciences
- 8.PS2.1Forces, Motion, and InteractionsApply Newton's Third Law to design a solution to a problem involving the motion of two objects in a system
- 8.PS2.2Forces, Motion, and InteractionsPlan 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.PS2.3Forces, Motion, and InteractionsAsk questions about data to determine the factors that affect the strength of electric and magnetic forces
- 8.PS2.4Gravity and Object MotionConstruct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects
- 8.PS2.5Forces, Motion, and InteractionsConduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact
- 8.PS4.1Light, Sound, and Wave BehaviorUse mathematical representations to describe patterns in a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave
- 8.PS4.3Integrate Qualitative Scientific Technical Information Claim Digitized SignalsIntegrate qualitative scientific and technical information to support the claim that digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information
LS Life Sciences
- 8.LS1.4Organism Needs, Structures, and Life CyclesUse arguments based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants, respectively
- 8.LS1.5Organism Needs, Structures, and Life CyclesConstruct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms
- 8.LS3.1Organism Needs, Structures, and Life CyclesDevelop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism
- 8.LS3.2Organism Needs, Structures, and Life CyclesDevelop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation
- 8.LS4.1Earth Materials, Rocks, Fossils, and LandformsAnalyze and interpret data to identify patterns within the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth
- 8.LS4.2Organism Needs, Structures, and Life CyclesApply scientific ideas to construct an explanation for the patterns of anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer ancestral relationships
- 8.LS4.3Displays Pictorial Data Patterns Similarities Embryological Development AcrossAnalyze displays of pictorial data to compare patterns of similarities in the embryological development across multiple species to identify relationships not evident in the fully formed anatomy
- 8.LS4.4Cells, Body Systems, and GeneticsConstruct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals' probability of surviving and reproducing in a specific environment
- 8.LS4.5Organism Needs, Structures, and Life CyclesGather and synthesize information about the practices that have changed the way humans influence the inheritance of desired traits in organisms
- 8.LS4.6Cells, Body Systems, and GeneticsUse mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time
ESS Earth and Space Sciences
- 8.ESS1.1Sun, Moon, Earth, Stars, and Space SystemsDevelop and use a model of the Earth-Sun-Moon system to describe the cyclic patterns of lunar phases, eclipses of the Sun and Moon, and seasons

- MS.ETS1.1Engineering Design and Solution EvaluationDefine the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions
- MS.ETS1.2Engineering Design and Solution EvaluationEvaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem
- MS.ETS1.3Engineering Design and Solution EvaluationAnalyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success
- MS.ETS1.4Engineering Design and Solution EvaluationDevelop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved
