Writing a Procedure

A procedure is a set of steps that tell how to do an activity or experiment. It should be VERY detailed. So detailed that if a person found this procedure, they could do the experiment exactly the way you did it. As part of your procedure, it is important to have your materials listed above so the person doing the activity already has everything they need.
