... is the study of atoms and molecules as they bond together to form the building materials of nature. Chemical principles and theories are presented in the classroom and laboratory.


[PS1] Matter and Its Interactions

  • SCI-HS.PS1.01  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.
  • SCI-HS.PS1.02  Construct 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.
  • SCI-HS.PS1.03  Plan and conduct an investigation to gather evidence to compare the structure of substances at the macro scale to infer the strength of electrical forces between particles.
  • SCI-HS.PS1.04  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.
  • SCI-HS.PS1.05  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.
  • SCI-HS.PS1.06  Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
  • SCI-HS.PS1.07  Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
  • SCI-HS.PS1.08  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.



[PS2] Motion and Stability: Forces and Interactions

  • SCI-HS.PS2.06  Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.



[PS3] Energy

  • SCI-HS.PS3.01  Create a mathematical model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
  • SCI-HS.PS3.02  Develop and use models to illustrate that energy is associated with motion and relative position of particles (objects).
  • SCI-HS.PS3.03  Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
  • SCI-HS.PS3.04  Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).



[ETS1] High School Engineering Design

  • SCI-HS.ETS1.01  Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
  • SCI-HS.ETS1.02  Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
  • SCI-HS.ETS1.03  Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts.
  • SCI-HS.ETS1.04  Use a computer simulation to model the impact of proposed solutions to a complex real-world problem with numerous criteria and constraints on interactions within and between systems relevant to the problem.
