Topic:

Gas Laws

Lesson Objective:

Students will apply the gas laws to solve problems.

Materials:

Practice problems

State Frameworks:

GL.16.C.2 Calculate the effects of pressure, temperature, and volume on the number of moles of gas particles in chemical reactions

GL.17.C.1 Calculate the effects of pressure, temperature, and volume to gases

NGSS

CII-PS4-1AR Plan and carry out investigations to examine stability and change exhibited by gas particles in a closed system. [Clarification Statement: Emphasis is on the relationships between pressure, volume, temperature, and quantity of particles (Graham's law of effusion, Dalton's law of partial pressure, gas stoichiometry).]

CII-PS4-2AR Argue from evidence cause and effect relationships of factors influencing behavior of gas particles. [Clarification Statement: Emphasis is on the kinetic molecular theory.]

CCSS:

RST.11-12.3 Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks; analyze the specific results based on explanations in the text

WHST.11-12.4 Produce clear and coherent writing in which the development, organization, and style are appropriate to task, purpose, and audience.

ACT Aspire PLD:

Constructing Explanations and Designing Solutions, Using Mathematics and Computational Thinking, Asking Questions and Defining Problems, Planning and Carrying Out Investigations, Analyzing and Interpreting Data

Science & Engineering Practices (SEP):

Using Mathematics and Computational Thinking, Engaging in Argument from Evidence, Constructing Explanations and Designing Solutions, Planning and Carrying Out Investigations

Crosscutting Concepts (CCC):

Patterns, Cause and Effect, Stability and Change, Systems and System Models

Disciplinary Core Ideas (DCI):

Engagement:

Opening Question: “List the gas law equations.”

5 min

Explore:

Students will spend some time attempting to apply the gas law equations to the practice problems. B-Day will rotate through lab as rest of class works on practice problems (until they complete the lab).

20 min

Explain:

Review the gas laws and demonstrate how to use each equation.

A-Day will start here (B-Day on 4/12 as needed). We will also discuss how to create a line graph and how to add a best-fit line (both A and B-Days)

20 min

Elaborate:

Students will use the remaining time to complete the practice problems.

45 min

Evaluate:

Formative as students work. Summative of practice problems.
