Enduring Understandings:
1. Chemical and physical properties of matter can be explained by the structure and the arrangements of atoms, ions, or molecules, and the forces between them.
2. Properties and reactions of matter can be quantified.
3. Lab activities apply the process of scientific investigation, and must be conducted safely, communicated, and evaluated.
Essential Questions:
1. What properties of gases make them different from the other states of matter?
2. How can you explain the relationship between any two of the following: pressure, temperature, volume, and amount? Justify with an everyday example.
Learning Objectives:
1. Explain how the KMT describes the behavior of gases.
2. State the definition and units for volume, temperature, pressure and amount
3. State the relationships between pressure, temperature, volume and amount (inverse or direct)
4. Solve for an unknown variable in the ideal gas law or in two or three variable gas law equations.
5. Complete calculations involving gas law equations and stoichiometric principles.
6. Complete calculations using Dalton’s Law of Partial Pressures
Learning Activities:
1. Gases Pre-quiz: complete the pre-quiz here.
2. KMT Activity: we will do this in class but in case you're absent you can access it here.
3. Pressure and STP
A. Watch the video below and take notes on your own.
B. Have your notes checked by the teacher.
4. 2 Variable Gas Laws
A. Watch the video below and TAKE NOTES!
B. Watch the video below with two practice problems and complete your notes. Have your notes checked for completion.
C. Complete the Charles' Law Oil Lab and turn in.
5. Ideal Gas Law
A. Complete the POGIL with 2 or 3 partners.
B. Try some easy gas laws practice questions that include 2 variable gas laws and the ideal gas law (OPTIONAL).
6. Dalton's Law
A. Watch the video below and TAKE NOTES! Have your notes checked for completion. (Correction: when calculating the partial pressure of Br2, I accidentally wrote 4.98... it should be 4.89).
