This is a volume mini lab I use with my matter unit.
All of my labs are easy to use in any classroom with everyday, inexpensive materials. Included is a lab sheet as well as PPT slides to guide discussion of the lab procedures.
This lab, along with many other great things, is included in my Matter Bundle as well!
