Structure and Properties of Matter

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 (valence electrons).
HS-PS1-3 Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
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.
- Classify nuclear reactions (Ch-G.1)
- Predict products and reactants in nuclear reactions (Ch-G.2)
HS-PS2-6 Communicate scientific and technical information about why the molecular-level structure is important in the functioning of natural and designed materials.
- Classify and describe covalent substances, ionic compounds, and metals (Ch-J.3)

Chemical Reactions

HS-PS1-2 Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-4 Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
- Matter and energy transfer between a system and its surroundings (Ch-E.1)
- Identify exothermic and endothermic processes (Ch-E.2)
HS-PS1-5 Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
- Determine the average reaction rate (Ch-U.1)
- Factors that affect reaction rate (Ch-U.2)
HS-PS1-6 Make arguments based on kinetic molecular theory to explain how altering conditions affects the forward and reverse rates of a reaction at equilibrium.
- Predict the equilibrium shift (Ch-V.2)
- Identify the stresses that cause an equilibrium shift (Ch-V.3)
HS-PS1-7 Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.

Waves and Electromagnetic Radiation

HS-PS4-1 Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
- Properties of electromagnetic waves (Ch-H.1)
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.
- The photoelectric effect and the particle nature of light (Ch-H.2)
- Atomic emission and absorption spectra (Ch-H.3)
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.
- Properties of electromagnetic waves (Ch-H.1)
