Develop models to describe the atomic composition of simple molecules and extended structures.

Performance Expectation

Grade: 
Middle School (6-8)
Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

Performance Expectation

Grade: 
Middle School (6-8)
Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.

Performance Expectation

Grade: 
Middle School (6-8)
Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.

Performance Expectation

Grade: 
Middle School (6-8)
Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

Performance Expectation

Grade: 
Middle School (6-8)
Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.*

Performance Expectation

Grade: 
Middle School (6-8)
Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects.*

Performance Expectation

Grade: 
Middle School (6-8)
Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.

Performance Expectation

Grade: 
Middle School (6-8)
Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.

Performance Expectation

Grade: 
Middle School (6-8)
Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
