Students know:

Behavior of gases is determined by the movement and interactions of the particles.
Relationships among the variables (pressure, volume, temperature, number of particles) can be used to predict the changes to a gaseous system.
The movement and interactions of gas particles within a system and the type of sytem determine the behavior of gases.
Relationships among the variables (pressure, volume, temperature, number of particles) can be used to predict the changes to a gaseous system.

Students are able to:

Plan an investigation that describes experimental procedure, including how data will be collected, number of trials, experimental setup, and equipment required.
Conduct an investigation to collect and record data that can be used to describe the relationship between the measureable properties of a substance and the motion of the particles of the substance.
Analyze recorded data to explain the behavior of ideal gases in terms of pressure, volume, temperature, and number of particles.
Identify relevant components in mathematical representations of the gas laws.
Analyze data using tools, technologies, and/ or models (e.g., computational, mathematical) in order to make valid and reliable scientific claims.
Use mathematical representations to determine the value of any relevant components in mathematical representations of the gas laws, given the other values.

Students understand that:

Scientists plan and conduct investigations individually and collaboratively to produce data to serve as the basis for evidence.
Changes in the variables that affect the motion of gas particles can be described and predicted using scientific investigations.
The patterns of interactions between particles at the atomic/ molecular/ particulate level are reflected in the patterns of behavior at the macroscopic scale.
Cause and effect relationships may be used to predict phenomena in natural or designed systems.
Mathematical representations of phenomena are used to support claims and may include calculations, graphs or other pictorial depictions of quantitative information.
Changes in the variables that affect the motion of gas particles can be described and predicted using scientific investigations.
Cause and effect relationships may be used to predict phenomena in natural or designed systems.
