PS 1 – Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells. (Organization of the body, and interaction of body systems) (MS-LS1-3)

PS 2 – Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories. (MS-LS1-8)

PS 3 – Develop models to describe the atomic composition of simple molecules and extended structures. (complex molecules, compounds, mixtures) (MS-PS1-1)

PS 4 – Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. (MS-PS1-2)

PS 5 – Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. (MS-PS1-3)

PS 6 – Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed. (MS-PS1-4)

PS 7 – Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. (MS-PS1-5)

PS 8 – Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes (NGSS example includes a chemical reaction such as dissolving and is limited to amount, time and temperature). (MS-PS1-6)

PS 9 – Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales.(MS-ESS2-2)

PS 10 – Construct a scientific explanation based on evidence for how the uneven distributions of Earth’s mineral (metal ores), energy (petroleum/natural gas), soil and groundwater resources are the result of past and current geoscience processes (rock cycle). Emphasize that these are typically limited and non-renewable resources.(MS-ESS3-1)
