The full text of every grade 8 science standard in the Minnesota K-12 Academic Standards in Science. If your Minnesota classroom or report card mentions a code, you will find it here.
1 Exploring phenomena or engineering problems
- 8P.1.1.1.1Particles, Atoms, Elements, and CompoundsAsk questions about locations of common elements on the periodic table to note patterns in the properties of similarly grouped elements
- 8P.1.1.1.2Forces, Motion, and InteractionsAsk questions about data to determine the factors that affect the strength of electric and magnetic forces
- 8P.1.2.1.1Chemical and Physical ChangesPlan and conduct an investigation of changes in pure substances when thermal energy is added or removed and relate those changes to particle motion
- 8P.1.2.1.2Forces, 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
- 8P.1.2.1.3Forces, 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
- 8P.1.2.1.4Matter Properties, States, and ClassificationPlan and conduct an investigation to determine how the temperature of a substance is affected by the transfer of energy, the amount of mass, and the type of matter
2 Looking at data and empirical evidence to understand phenomena or solve problems
- 8P.2.1.1.1Material Properties and UsesAnalyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred
- 8P.2.1.1.2Data Analysis, Patterns, and Model LimitsConstruct and interpret graphical displays of data to describe the relationship of kinetic energy to the mass and speed of an object
- 8P.2.2.1.1Light, Sound, and Wave BehaviorUse mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave
- 8P.2.2.1.2Energy Forms, Transfer, and TransformationCreate a computer program to illustrate the transfer of energy within a system where energy changes form
3 Developing possible explanations of phenomena or designing solutions to engineering problems
- 8P.3.1.1.1Particles, Atoms, Elements, and CompoundsDevelop models to describe the atomic composition of simple molecules and crystals
- 8P.3.1.1.2Particles, Atoms, Elements, and CompoundsDevelop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved
- 8P.3.1.1.3Revise When Arrangement Objects Interacting Distance Changes DifferentDevelop and revise a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system
- 8P.3.1.1.4Light, Sound, and Wave BehaviorDevelop and use a model to qualitatively describe that waves are reflected, absorbed, or transmitted through various materials
- 8P.3.2.1.1Explanation Based Evidence Scientific Principles Common Phenomenon ExplainedConstruct an explanation based on evidence and scientific principles of a common phenomenon that can be explained by the motions of molecules
- 8P.3.2.2.1Chemical and Physical ChangesConstruct, test and modify a device that either releases or absorbs thermal energy by chemical processes

- 8P.3.2.2.3Energy Forms, Transfer, and TransformationDesign, construct, and test a device that either minimizes or maximizes thermal energy transfer
4 Communicating reasons, arguments and ideas to others
- 8P.4.1.1.1Lab Safety and Responsible InvestigationsConstruct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects
- 8P.4.1.1.2Energy Forms, Transfer, and TransformationCompare and evaluate evidence to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object
- 8P.4.2.1.1Natural Resources and Human ImpactsGather and evaluate information from multiple sources to describe that synthetic materials come from natural resources and impact society
- 8P.4.2.1.2Integrate Qualitative Scientific Technical Information Claim Digitized SignalsIntegrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals
