Chemical Equations and Reactions
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 are systems affected by change(s)?
- 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.
- 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.
- 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
ASSIGNMENT:
1. Watch the videos.
2. Create a bubble map about the Law of Conservation of Mass .
ASSIGNMENT:
1. Preview the Conservation of Mass lab we will do in class.
2. Then, get a copy of the conservation of mass lab from me.
3. Write down or tell me any safety precautions you will need to take during the lab.
ASSIGNMENT:
1. Get a copy of the PHET balancing Equations Lab from me.
2. You will use the virtual lab to practice and visualize balancing equations.
ASSIGNMENT:
1. As you watch the video above, create a bubble map about the different Chemical Symbols used in chemical equations. You should be sure to include what the symbols (aq), (l), (s) and (g) mean when used in a chemical equation.
ASSIGNMENT:
1. Watch the video on balancing chemical equations for beginners.
2. Then, watch the KHAN academy version .
3. As you watch, create a bubble map on Balancing Chemical Equations.
ASSIGNMENT:
1. Complete the virtual lab above on balancing chemical equations.
2. The instructions for the lab are on the left side of the screen.
3. When you are done, open the journal icon and answer the journal questions on your own sheet of paper using complete sentences.
4. Once this is completed, see me for some balancing equations practice.
ASSIGNMENT:
1. Take out a sheet of paper and write "Types of Chemical Reactions" at the top.
2. Next, divide the paper in to hamburger, then divide it in thirds while it's still folded hamburger to create 6 sections.
3. At the top of the sections write: "Single Replacement", "Double Replacement", "Combustion", "Synthesis" and "Decomposition".
4. Watch the video and take notes on the different types of reactions.
5. See me for a card sort, to practice identifying the types of reactions.
ASSIGNMENT: See me for a copy of the types of reactions art project.
You are done with the unit! See me for some hands-on lab options if you're done early .
