Science (2015) Grade(s): 09-12 - Physical Science

SC15.PS.2
Plan and carry out investigations (e.g., squeezing a balloon, placing a balloon on ice) to identify the relationships that exist among the pressure, volume, density, and temperature of a confined gas.

Cause and Effect

Knowledge

Students know:

Gases can be compressed very tightly or expanded to fill a very large space.
As the temperature of a gas increases, the gas particles move faster and hit the sides of their container more frequently.
As the temperature of a gas decreases, the gas particles move more slowly and hit the sides of their container less frequently.

Skills

Students are able to:

Plan and carry out investigations to determine the relationship of the variables: pressure, temperature, volume, and density.
Create graphical representations of data from the investigation.
Analyze and interpret data from the investigation.
Communicate information collect from the investigations.
Use safe lab procedures.

Understanding

Students understand that:

The changes in volume, pressure and temperature of a gas demonstrate a pattern that can be related mathematically.
These relationships can be direct or indirect.
