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. |

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. |
