Battaglia’s Chemistry 2015-2016: Unit 2: Atomic Structure Resources

NOTE: This information only represents the general sequencing of resources for lessons, not all of the instructional strategies involved. This work was done in the summer of 2015, and represents my initial thoughts on transitioning to the NGSS. 

Unit 2: Atomic Structure

From the Big Bang to MRIs

Key Essential Questions:

  • What are the characteristic properties and behaviors of waves?
  • What forces hold nuclei together and mediate nuclear processes?
  • How do particles interact to form the variety of matter one observes?

Transfer Goals:

Students will be able to independently use their learning to

  • Create and use models to illustrate and predict changes in atomic structure.
  • Apply scientific understanding of atomic structure and stability to explain the composition of matter in the universe.
  • Use mathematical and computational thinking to evaluate the relationship between waves and particles.

Performance Expectations:

HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.  
HS-PS1-8. Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.
HS-PS4-1. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
HS-PS4-3.  Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.
HS-PS4-4.  Evaluate the validity and reliability of claims in published materials of the effects that different frequencies of electromagnetic radiation have when absorbed by matter.
HS-ESS1-1. Develop a model based on evidence to illustrate the life span of the sun and the role of nuclear fusion in the sun’s core to release energy that eventually reaches Earth in the form of radiation.
HS-ESS1-2. Construct an explanation of the Big Bang theory based on astronomical evidence of light spectra, motion of distant galaxies, and composition of matter in the universe.  
HS-ESS1-3. Communicate scientific ideas about the way stars, over their life cycle, produce elements.
HS-ESS1-6. Apply scientific reasoning and evidence from ancient Earth materials, meteorites, and other planetary surfaces to construct an account of Earth’s formation and early  history.

Unit Driving Question: How does atomic structure help explain our past, present, and future?

Guiding Questions: How are planets and stars formed? Where do elements come from?(general background info.–use these to start discussions about the evidence)

Guiding Question: How do we define atomic structure?

Guiding Question: How do we know how the Earth formed, and what the planet was like then?

Guiding Questions: How are atoms stable? How does atomic structure change, and what is the result of those changes?

Guiding Question: How is the manipulation of atomic structure used in everyday life?

Performance Task “Atomic Impact”: NOT READY YET
