7-MS-PS1 Matter and Its Interactions

  • 7-MS-PS1-2 Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

  • 7-MS-PS1-4 Develop a model that predicts and describes changes in particle motion, temperature, and the state of a pure substance when thermal energy is added or removed.

  • 7-MS-PS1-5 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.

7-MS-PS3 Energy

  • 7-MS-PS3-4 Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.

7-MS-ESS2 Earth's Systems

7-MS-ESS3 Earth and Human Activity

7-MS-LS1 From Molecules to Organisms: Structures and Processes

  • 7-MS-LS1-3 Use an argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

  • 7-MS-LS1-6 Construct a scientific explanation based on evidence for the role of photosynthesis and cellular respiration in the cycling of matter and flow of energy into and out of organisms.

  • 7-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.

7-MS-LS2 Ecosystems: Interactions, Energy, and Dynamics

7-MS-LS3 Heredity: Inheritance and Variation of Traits

7-MS-LS4 Biological Evolution: Unity and Diversity
