SC.8.1 Forces and Interactions

  • SC.8.1.1 Gather, analyze, and communicate evidence of forces and interactions.

    • SC.8.1.1.A Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.

    • SC.8.1.1.B Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

    • SC.8.1.1.C Plan 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.

    • SC.8.1.1.D Ask questions about data to determine the factors that affect the strength of electrical and magnetic forces.

    • SC.8.1.1.E Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

    • SC.8.1.1.F Conduct 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.

SC.8.2 Waves and Electromagnetic Radiation

  • SC.8.2.2 Gather, analyze, and communicate evidence of waves and electromagnetic radiation.

    • SC.8.2.2.A Use 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.

    • SC.8.2.2.B Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

    • SC.8.2.2.C Integrate 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.

SC.8.4 Energy

SC.8.9 Heredity: Inheritance and Variation of Traits

SC.8.10 Natural Selection and Adaptations

SC.8.11 Space Systems

  • SC.8.11.6 Gather, analyze, and communicate evidence of the interactions among bodies in space.

    • SC.8.11.6.A Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.

    • SC.8.11.6.B Develop and use a model to describe the role of gravity in the motions within the galaxy and the solar system.

    • SC.8.11.6.C Analyze and interpret data to determine scale properties of objects in the solar system.

SC.8.14 History of Earth

  • SC.8.14.7 Gather, analyze, and communicate evidence to explain Earth's history.

    • SC.8.14.7.A Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth's 4.6- billion-year-old history.
