Reflection: Rigor Rates of a Reaction and Factors that Affect a Reaction - Section 2: Engage


Although the act of asking questions sounds easy it is one of the NGSS practices that I have struggled with throughout the school year.  As I was planning the unit I realized that using a demonstration is a great way to get students engaged and ask questions.  

For this lesson I  had students come up with questions as they watched the demonstration and then add to and revisit their questions as they learned new information.  Furthermore, they were then able to answer their questions at the end of the unit.  Overall, I am really pleased with how this went as that I got some really good questions from students!

Rates of a Reaction and Factors that Affect a Reaction

Unit 8: Unit 9: Reaction Rates and Equilibrium
Lesson 1 of 6

Objective: Students will be able to describe what happens to concentration of reactants/products and energy in chemical reactions as well as the factors that affect chemical reactions as demonstrated by watching a demonstration, performing an activity, and taking notes.

Big Idea: Chemical reaction rates are described as the use of reactants or production of products over time. There are factors that affect reaction rates including concentration, temperature, surface area, and catalysts.
