Lab Design

Power Investigation. You are given a sound intensity meter and a Bose speaker. Design a lab to determine the Power of the speaker at various volume settings. Make a prediction of what a scatter plot would look like.

Variables Description:  A valuable way to make sure you include all your variables appropriately is to make up a table like this before you do the experiment .

Independent Variable (what you are changing)

Dependent Variable (what you are measuring)

Controlled Variables (those factors that need to be held the same in each trial to ensure a fair test)

 

 

 

Procedures:  In point numbered format, summarize step-by-step what you will be doing to carry out the lab.  These should be in your own words, and should include ALL details as these are your lab directions.  The steps should be clear enough for anyone else to follow.  If you use a specialized apparatus, include a labeled diagram.  You may also include a table of how your trials will be set up if it makes your procedure more clear.
