Procedure: Outline the steps followed when doing the demonstration. Observations: State what the observation should be (e.g., for "eddy currents" associated with a Lenz's law demonstration of the stalled magnet in the copper pipe, you should notice that the magnetic slug drops much slower through the pipe than a non-magnetic slug). Analysis: This is the important section where you clearly explain the phenomenon observed. Show your understanding and enable others to understand. Reference: State where the idea for the demonstration came from. It is perfectly acceptable to use a demonstration that you have read about, but you must put the information and explanation in your own words
