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 functions of the components in a system related to the structures and / or processes of the system?
- How can one system be considered a component of another system?
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?
- To what extent do limitations of models affect their reliability, validity, and usefulness?
Patterns of constancy and change in systems can be observed, measured, and / or modeled.
- 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?
- In what ways do interactions affect the basic properties of a system?
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?
Scientific decision-making is a way of answering questions about systems within the natural world.
- Who should be scientifically literate and why?
- What does it mean to be scientifically literate?
- How does scientific decision-making affect the quality of our lives?
- What distinguishes decision-making in science from decision-making in other areas of study?
ASSIGNMENT:
1. Watch the video on dimensional analysis.
2. Then, complete the dimensional analysis practice problems from the Khan academy links on the right using the methods you watched in the video. Complete both practices- there are two links above.
3. See me for a copy of the "islander" problem. Can you use the patterns to determine how many turtles are on the island? Use the patterns you've learned above for dimensional analysis to solve. You may color and cut the pieces out to solve (it would be hard not to!) and NOT ALL PIECES ARE USED! See me BEFORE CUTTING to make sure you cut out pieces correctly!!!!!
ASSIGNMENT:
1. Watch the video on the mole.
2. As you watch, create a bubble map about the mole. Be sure to include how big a mole is (including in volume)!
3. If you struggle with scientific notation (like 10^23) then please use the scientific notation video to review how to use scientific notation.
1) Watch the video above for more exposure on calculating molar mass.
2) See me for a copy of molar mass practice calculations. You will need to use your skills from previous units on naming compounds! See me if you need a refresher.
ASSIGNMENT:
1) Watch the videos above on using the Mole for calculations.
2) See me for a paper copy of the Unlocking the Mole Practice.
ASSIGNMENT:
1. Complete the Moles of chalk lab.
2. You will need to see me for a copy.
ASSIGNMENT:
1. Watch the video above on moles and volume conversions. Add the conversion factor to your notes on moles.
2. Then, see me for the moles and volume lab. You will be calculating how many moles of gas are in this room.
ASSIGNMENT:
1. Select one of the videos above on calculating percent composition.
2. Create a bubble map for Percent Composition by Mass.
3. Then, get a copy of percent composition problems from me to complete, using the video as a model.
4. For bonus points or if you'd rather, see me for the Mole and Airplane explosion murder mystery!
ASSIGNMENT: Given the cost of a roll of aluminum foil ($1.99) and its total area (75 square feet)
1. plan and implement an investigation to determine the cost of a single atom of Al.
2. Record all assumptions, procedures, data, and calculations.
3. Summarize how Avogadro’s number and molar mass were used.
ASSIGNMENT: Use the links above for more virtual mole practice to prepare for your unit exam.
Done early? You may work on your semester exam review.
