Reflection: Classroom Setup LA + B --> L + AB - Section 1: Background


I have the joy this year of switching rooms every time I teach chemistry.  My schedule is:

  • Period 1- Off
  • Period 2- Chemistry, Room A
  • Period 3- Off
  • Period 4- Chemistry, Room B
  • Period 5- Lunch
  • Period 6- Chemistry, Room A
  • Period 7- AP Chemistry, Room B
  • Period 8- Chemistry, Room B

Due to this scheduling quirk, I try to design my labs to be as mobile as possible.  Some times I will run an activity in room A today, and then room B tomorrow.  Other times I move the setups every period.  Today was a day to be mobile.  To make life easier, I have taken to doing labs in stations, so I don't have to prep the same chemicals for 7 lab tables.

The other adaptation has been getting some clear tubs to move the lab back and forth.  Below are photos of the four setups for this experiment.

Reaction 2:

Reaction 3:

Reaction 4:

By having larger containers, and a single place for waste, this tremendously reduces both my prep and post-lab cleanup.  It also helps students know exactly what they need, since all equipment is present on the table for them, and time is not lost digging through a drawer searching for the right piece.

LA + B --> L + AB

Unit 6: Chemical Reactions
Lesson 7 of 10

Objective: SWBAT work safely in lab to identify single and double replacement reactions.

Big Idea: Knowing the type of reaction helps in predicting the outcome.
