PS Physical Sciences

  • 8-PS2 Motion and Stability: Forces and Interactions

    • 8-PS2-1 Design and conduct investigations depicting the relationship between magnetism and electricity in electromagnets, generators, and electrical motors, emphasizing the factors that increase or diminish the electric current and the magnetic field strength.

    • 8-PS2-2 Conduct an investigation to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

    • 8-PS2-3 Create a demonstration of an object in motion and describe the position, force, and direction of the object.

    • 8-PS2-4 Plan and conduct 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.

    • 8-PS2-5 Evaluate and interpret that for every force exerted on an object there is an equal force exerted in the opposite direction.

  • 8-PS4 Waves and Their Applications in Technologies for Information Transfer

    • 8-PS4-1 Develop and use models to represent the basic properties of waves including frequency, amplitude, wavelength, and speed.

    • 8-PS4-2 Compare and contrast mechanical waves and electromagnetic waves based on refraction, reflection, transmission, absorption, and their behavior through a vacuum and/or various media.

    • 8-PS4-3 Evaluate the role that waves play in different communication systems.

LS Life Sciences

ESS Earth and Space Sciences

  • 8-ESS1 Earth's Place in the Universe

    • 8-ESS1-1 Research, analyze, and communicate that the universe began with a period of rapid expansion using evidence from the motion of galaxies and composition of stars.

    • 8-ESS1-2 Explain the role of gravity in the formation of our sun and planets. Extend this explanation to address gravity's effect on the motion of celestial objects in our solar system and Earth's ocean tides.

  • 8-ESS2 Earth's Systems

  • 8-ESS3 Earth and Human Activity

    • 8-ESS3-1 Interpret data to explain that earth's mineral, fossil fuel, and groundwater resources are unevenly distributed as a result of geologic processes.

    • 8-ESS3-2 Collect data, map, and describe patterns in the locations of volcanoes and earthquakes related to tectonic plate boundaries, interactions, and hotspots.

ETS Engineering, Technology, and Applications of Science

  • 8-ETS1 Engineering Design

    • 8-ETS1-1 Develop a model to generate data for ongoing testing and modification of an electromagnet, a generator, and a motor such that an optimal design can be achieved.

    • 8-ETS1-2 Research and communicate information to describe how data from technologies (telescopes, spectroscopes, satellites, and space probes) provide information about objects in the solar system and universe.
