Try out this though-provoking capstone demonstration for the Chemical Reactions unit!
Michael Jansen reflects on a very common empirical formula lab that asks students to determine the empirical formula of MgxOy. He then explains how he continues to use it as a "successful failure", how he demonstrates an alternate procedure and leads his students to an important lesson.
The Types of Chemical Reactions Lab is a favorite for many teachers and students. Chemistry comes to life as students record observations. This virtual version by no means replaces the students physically conducting the reactions themselves but during these times this activity can be used to supplement the teaching of chemical reactions.
I expect that most high school chemistry teachers assign some type of laboratory related to types of chemical reactions including synthesis, decomposition, single replacement and double replacement reactions. I have used several published versions, but I am sharing my modifications.
