Battaglia’s Chemistry 2015-2016: Unit 5: Rates & Stability of Chemical Reactions

NOTE: This information only represents the general sequencing of resources for lessons, not all of the instructional strategies involved. This work was done in the summer of 2015, and represents my initial thoughts on transitioning to the NGSS. 

Unit 5: Rates & Stability of Chemical Reactions

Key Essential Questions:

  • How do various factors affect how quickly a reactions reaches completion?
  • Why are some systems more stable than others?
  • What are the characteristics of a chemical reaction system that never reaches completion?

Transfer Goals:

Students will be able to independently use their learning to

  • Apply knowledge of chemical reactions to demonstrate the cause and effect relationship of variables in a system at equilibrium.
  • Construct an explanation of the variables affecting the rate of a chemical reaction.
  • Develop a model illustrating the changes in energy in a chemical system.
  • Evaluate design solutions for energy and other resources in regards to cost vs. benefits.

Performance Expectations:

HS-PS1-4. Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.  
HS-PS1-6. Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.*  
HS-ESS3-2. Evaluate competing design solutions for developing, managing, and utilizing energy and mineral resources based on cost-benefit ratios.*

  1. Would you mind sharing some of the Guiding Questions and Activities you developed for this unit? Thank you for an excellent resource!

    • I am sorry to say that I never finished this work..I took a position this last school year (after posting that) as an instructional coach, and I have not had time to work on it further. If time allows this summer, I will try to add some ideas in there. Thanks for visiting the blog!
