This Fog Chamber lesson plan also includes:
Create a fog chamber in a jar in order to explore the process of fog or cloud formation. A materials list and assembly instructions are explained, as well as a section about what to notice during the exploration. The laboratory sheet is not written in standard scientific method format. Another unfortunate error is that the vapor is refered to as "smoke" several times. Perhaps you can use this resource for your own reference, but create a separate handout for your class.
