This is my first year of using Modeling Instruction in my chemistry classes. During a fit of productivity, I created some bell ringers for unit one, which is partly about conservation of mass. I hope you will find them useful. Comments are welcome. I would love to see what others might be using.
You can access the bell ringers below. They are part of the "student document".
Concepts:
Conservation of mass
Time required:
Approximately 5 minutes per class period.
Background:
These are bell ringers for use while teaching conservation of mass.
Procedure:
Provide one bell ringer per day to get class started. Project it for students and give them just a few minutes to complete.
Preparation:
none
Attribution:
I created these myself while using Modeling Instruction.
