7.MS-ESS2-4 Develop a model to explain how the energy of the sun and Earth's gravity drive the cycling of water, including changes of state, as it moves through multiple pathways in Earth's hydrosphere.
7.MS-ESS3-4 Construct an argument supported by evidence that human activities and technologies can to mitigate the impact of increases in human population and per capita consumption of natural resources on the environment.
7.MS-LS1 From Molecules to Organisms: Structures and Processes
7.MS-LS1-4 Construct an explanation based on evidence for how characteristic animal behaviors and specialized plant structures increase the probability of successful reproduction of animals and plants.
7.MS-LS2-2 Describe how relationships among and between organisms in an ecosystem can be competitive, predatory, parasitic, and mutually beneficial and that these interactions are found across multiple ecosystems.
7.MS-LS2-6(MA) Explain how changes to the biodiversity of an ecosystem—the variety of species found in the ecosystem—may limit the availability of resources humans use.
7.MS-PS Physical Science
7.MS-PS2 Motion and Stability: Forces and Interactions
7.MS-PS2-3 Analyze data to describe the effect of distance and magnitude of electric charge on the strength of electric forces.
7.MS-PS2-5 Use scientific evidence to argue that fields exist between objects with mass, between magnetic objects, and between electrically charged objects that exert force on each other even though the objects are not in contact.
7.MS-PS3-1 Construct and interpret data and graphs to describe the relationships among kinetic energy, mass, and speed of an object.
7.MS-PS3-4 Conduct an investigation to determine the relationships among the energy transferred, how well the type of matter retains or radiates heat, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.
7.MS-PS3-6(MA) Use a model to explain how thermal energy is transferred out of hotter regions or objects and into colder ones by convection, conduction, and radiation.
7.MS-PS3-7(MA) Use informational text to describe the relationship between kinetic and potential energy and illustrate conversions from one form to another.
7.MS-ETS1 Engineering Design
7.MS-ETS1-2 Evaluate competing solutions to a given design problem using a decision matrix to determine how well each meets the criteria and constraints of the problem. Use a model of each solution to evaluate how variations in one or more design features, including size, shape, weight, or cost, may affect the function or effectiveness of the solution.
7.MS-ETS1-7(MA) Construct a prototype of a solution to a given design problem.
7.MS-ETS3 Technological Systems
7.MS-ETS3-1(MA) Explain the function of a communication system and the role of its components, including a source, encoder, transmitter, receiver, decoder, and storage.
7.MS-ETS3-2(MA) Compare the benefits and drawbacks of different communication systems.
7.MS-ETS3-3(MA) Research and communicate information about how transportation systems are designed to move people and goods using a variety of vehicles and devices. Identify and describe subsystems of a transportation vehicle, including structural, propulsion, guidance, suspension, and control subsystems.
7.MS-ETS3-4(MA) Show how the components of a structural system work together to serve a structural function. Provide examples of physical structures and relate their design to their intended use.
7.MS-ETS3-5(MA) Use the concept of systems engineering to model inputs, processes, outputs, and feedback among components of a transportation, structural, or communication system.
