Reflection: Routines and Procedures Le Chatelier's Lab and Unit 9 Review - Section 2: Explain

 

Over the years I have found that one of the most difficult parts of being a good chemistry teacher is having my students do labs.  I believe that students need the hands-on experience of doing labs, but they are LOTS OF WORK!

  • You need to figure out good labs to do that coincide with the topics.
  • You need to make sure you have all of the necessary materials and equipment.
  • You need to set up and break down the labs.

This last part of setting up and breaking down the labs is much easier when I make "lab kits" for each lab that I do.  These kits take a little bit of extra time the first time I make them, but then it is much easier to share with colleagues and to use in subsequent years.

I make sure that when I order chemicals that I also order clear plastic tubs and lots of little dropper bottles and containers.  I then make enough materials for each lab station and label each of the materials well so that I can keep them together in the bin.   Then, in my backroom I have lots of these tubs which are labeled with the lab so that it is easy for me to grab the lab and setup for the next year.   These are "mostly" complete kits and would just need the glassware or other equipment added when placed on the tables.

Le Chatelier's Lab and Unit 9 Review

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

Objective: Students will be able to explain what factors will make an equilibrium system shift towards the products through performing a lab.

Big Idea: Equilibrium systems will shift to counteract stresses.
