Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

Performance Expectation

Grade:  Middle School (6-8)
Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.

Performance Expectation

Grade:  Middle School (6-8)
Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

Performance Expectation

Grade:  Middle School (6-8)
Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.*

Performance Expectation

Grade:  Middle School (6-8)
Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.

Performance Expectation

Grade:  Middle School (6-8)
Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.

Performance Expectation

Grade:  Middle School (6-8)
Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.

Performance Expectation

Grade:  Middle School (6-8)
Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

Performance Expectation

Grade:  Middle School (6-8)
Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.

Performance Expectation

Grade:  Middle School (6-8)
Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.
