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.

Performance Expectation

Grade: 
High School (9-12)
Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.*

Performance Expectation

Grade: 
High School (9-12)
Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.

Performance Expectation

Grade: 
High School (9-12)
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.

Performance Expectation

Grade: 
High School (9-12)
Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.

Performance Expectation

Grade: 
High School (9-12)
Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.

Performance Expectation

Grade:

Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.*

Performance Expectation

Grade: 
High School (9-12)
Use mathematical representations of Newton’s Law of Gravitation and Coulomb’s Law to describe and predict the gravitational and electrostatic forces between objects.

Performance Expectation

Grade: 
High School (9-12)
Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.
