Course: Chemistry

Create a computational 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.
Education Level: 12
Subject: science

Develop and use models to illustrate that energy at the macroscopic scale can be accounted for as a combination of energy associated with the motions of particles (objects) and energy associated with the relative positions of particles (objects).
Education Level: 12
Subject: science

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).
Education Level: 12
Subject: science

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.
Education Level: 12
Subject: science

Analyze data to support the claim that the combined gas law describes the relationships among volume, pressure and temperature for a sample of an ideal gas.
Education Level: 12
Subject: science

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.
Education Level: 12
Subject: science

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.
Education Level: 12
Subject: science

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.
Education Level: 12
Subject: science

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.
Education Level: 12
Subject: science

Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
Education Level: 12
Subject: science

Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
Education Level: 12
Subject: science

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.
Education Level: 12
Subject: science

Use mathematical representations to describe the composition and properties of individual solutions and solutions involved in chemical reactions.
