Food webs MS-LS1-7. Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism. Cycling of matter Food molecules Oxygen Energy (NGSS.nsta) MS-ESS2-1. Develop a model to describe the cycling of Earth’s materials and the flow of energy that drives this process. Rock cycle driven by earth’s hot interior Observable chemical/physical changes Sun energy drives movement of wind/water leads to weathering, erosion, and deposition. Land formations Review water cycle (NGSS.nsta) Video Series: How the Earth was Made (, ) MS-PS1-2*(main emphasis here). Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. Chemical and physical properties, changes / reactions Evidence of rearrangement of atoms Chemical/Physical properties and reactions of rocks Chemical/Physical weathering (NGSS.nsta) MS-PS1-5*(main emphasis here). 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. Reactants and products Balancing equations Law of conservation of mass (NGSS.nsta) MS-PS1-6. Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. Exothermic/Endothermic reactions Transfer of thermal energy between devices (NGSS.nsta) MS-ETS1-1. Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and Apply engineering design standards to MS-PS-1-6
Performance Expectations Core Concepts (Key topics) Resources MS-LS2-4. Construct an argument supported by empirical data that changes to physical or biological components of an ecosystem affect populations. Shifts in Populations Resource availability (NGSS.nsta) FOSS Kit: Populations and Ecosystems MS-LS2-5. Evaluate competing design solutions for maintaining biodiversity and ecosystem services. Ecosystems services Minimizing impact on ecosystems Maintaining biodiversity (NGSS.nsta) FOSS Kit: Populations and Ecosystems MS-ESS2-2. Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales. Geoscience processes Earth’s plate movement Erosion and weathering Rapid catastrophic events (NGSS.nsta) FOSS Kit: Earth History MS-ESS3-2. Analyze and interpret data on natural hazards to forecast future catastrophic events and inform the development of technologies to mitigate their effects. Forecasting Catastrophic Events Location Frequency Severity Damage (NGSS.nsta) FOSS kit: Earth’s History MS-PS1-3* (emphasize impact on society) Gather and make sense of information to describe that synthetic materials come from natural resources and impact society. Synthetic Materials and Humans Impact on society (NGSS.nsta) FOSS Kit: Chemical Interactions MS-ETS1-1. Define 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.
