Universal laws and other relationships are used to analyze, understand, and explain chemical interactions and phenomena in everyday life.
- What chemical laws or relationships can be applied to or derived from a given system?
- In what ways is an understanding of chemistry useful in everyday life?
A system is a collection of interactive, interrelated, or interdependent structures, and / or processes.
- How are the components and parameters of a system defined?
- How can one system be considered a component of another system?
Physical, mathematical, or conceptual models can be used to describe, investigate, and make predictions about a system in terms of its components and how they relate to each other, to the whole, and to the external environment.
- In what ways are models used to help us interpret systems?
Patterns of constancy and change in systems can be observed, measured, and / or modeled.
- Why is it important to observe, measure and / or model patterns of a system?
- What information do patterns provide about a system(s)?
A system can be described by its basic properties and analyzed in terms of interactions.
- In what ways can a system be described by its properties?
- How are interactions within a system analyzed?
Scientific processes are used to explore and understand a system.
- In what ways can a system be scientifically examined?
- Which scientific processes are most appropriate when studying a system and why?
- What significant conclusions can be drawn from investigating a system?
1. Get a copy of the PHET Gas Law simulation from me and use the link above to complete the virtual exploration of the different gas laws and relationships between pressure, temperature, volume and moles of a gas.
2. Write 4-6 sentences summarizing your observations from the virtual lab.
ASSIGNMENT:
1. Take a paper and divide it in fourths (hamburger then hot dog).
2. At the top of the sections, write: "Boyle's Law", "Charles's Law", "Combined Gas Law", "Avogadro's Law".
3. As you watch the video above, take notes on the different laws. Be sure to include equations for the different laws.
4. See me for a copy of Boyle's and Charles's Laws Practice.
ASSIGNMENT:
1. As you watch the video above, create a bubble map over The Ideal Gas Law.
2. Be sure to include the equation!
ASSIGNMENT:
1. Watch the video above on choosing which gas law equation to use.
2. Then, get a copy of gas laws practice packet from me.
3. Be sure to show your work on all problems for credit!
ASSIGNMENT:
1. You will put your gas laws to work in the "popping the ideal gas laws" lab.
2. See me for a copy of the lab instructions.
3. Give a written summary of what you'll be doing in the lab and that's when I know you're ready.
4. Be sure to include safety precautions you will need to take.
5. After you complete the lab, you will work out calculations related to the popping popcorn.
6. Finally, write 3-5 sentences summarizing what you've learned.
1) Watch the videos on gas stoichiometry (hooray! more stoichiometry!) .
2) See me for a copy of gas stoichiometry practice, and complete the practice using the videos and our past knowledge of stoichiometry as a base to work from.
3) NOTE- the main difference will be when the gas is NOT at STP. Otherwise, it follows the same, exact pattern we've done already!
ASSIGNMENT:
1. Create a visual aid, such as a poster, that illustrates the ideal gas assumptions and the gas laws (pressure, volume, temperature, and moles).
2. Show sample calculations for each gas law.
You are done!
