Air Bag Lab Results

Students review and discuss the results from their model airbag experiment. Our host speaks with Lea Merriwether, water quality technician at Georgia Aquarium, to discuss how gas levels affect water quality.

Crosscutting Concepts

Patterns

Observed patterns of forms and events guide organization and classification, and they prompt questions about relationships and the factors that influence them.

Stability and Change

For natural and built systems alike, conditions of stability and determinants of rates of change or evolution of a system are critical elements of study.

Science & Engineering Practices

Engaging in Argument from Evidence

The study of science and engineering should produce a sense of the process of argument necessary for advancing and defending a new idea or an explanation of a phenomenon and the norms for conducting such arguments. In that spirit, students should argue for the explanations they construct, defend their interpretations of the associated data, and advocate for the designs they propose. (NRC Framework, 2012, p. 73)

Vocabulary

activation energy - the minimum amount of energy that reactants must possess in order to undergo a specific reaction. 

catalyst - a substance that provides a lower energy pathway for reactants to convert to products without getting used up or changing itself. 

collision theory - a theory that states that particles must collide in order to react. 

effective collision - collisions that result in a successful reaction.

ideal gas - gas that follows the behavior described by kinetic molecular theory. 

ineffective collision - collisions that do not result in a successful reaction. 

kinetic energy - the energy of motion. 

kinetic molecular theory - A theory of the thermodynamic behavior of matter, especially the relationships among pressure, volume, and temperature in gases, based on the dependence of temperature on the kinetic energy of the particles of a substance. 

reaction rate - the change in concentration of a reactant or product over time. 

Georgia Standards of Excellence

SC4Obtain, evaluate, and communicate information about how to refine the design of a chemical system by applying engineering principles to manipulate the factors that affect a chemical reaction.

SC4.aPlan and carry out an investigation to provide evidence of the effects of changing concentration, temperature, and pressure on chemical reactions. (Clarification statement: Pressure should not be tested experimentally.)

SC5Obtain, evaluate, and communicate information about the Kinetic Molecular Theory to model atomic and molecular motion in chemical and physical processes.

SC5.cDevelop and use models to quantitatively, conceptually, and graphically represent the relationships between pressure, volume, temperature, and number of moles of a gas.

SPS5Obtain, evaluate, and communicate information to compare and contrast the phases of matter as they relate to atomic and molecular motion.

SPS5.bPlan and carry out investigations to identify the relationships among temperature, pressure, volume, and density of gases in closed systems. (Clarification statement: Using specific Gas laws to perform calculations is beyond the scope of this standard; emphasis should focus on the conceptual understanding of the behavior of gases rather than calculations.)
