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 systems affected by change(s)?
- How can one system be considered a component of another system?
Mathematical 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?
- In what ways do interactions affect the basic properties of a system?
Scientific processes are used to explore and understand a system.
- What makes a process scientific?
- 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?
Scientific decision-making is a way of answering questions about systems within the natural world.
- How does scientific decision-making affect the quality of our lives?
ASSIGNMENT:
1. Use the weblink above to become familiar with reactants, products and leftovers in a reaction.
2. Try the activity at various levels.
3. Then, write a 3-5 sentence summary about what you learned about reactants, products and leftovers using complete sentences.
ASSIGNMENT:
1. Get a copy of the Hamburger lab from me.
2. Complete the Hamburger lab to introduce yourself to stoichiometry.
ASSIGNMENT:
1. Watch the videos above on stoichiometry and create a bubble map about Stoichiometry.
2. Share with a neighbor and add anything you may have missed.
3. Then, see me for some Stoichiometry practice and the Stoichiometry road-map to assist you.
ASSIGNMENT:
1. Watch the videos above on limiting reagents.
2. As you watch, create a bubble map over Limiting Reagents.
3. Share with a neighbor and add anything they had that you may have missed.
ASSIGNMENT:
1. Create a double-bubble map comparing and contrasting percent yield to theoretical yield as you watch the videos above.
2. Then, see me for a copy of the Percent Yield Practice.
ASSIGNMENT:
