First: See that the balance pan is in place and the weights and dial are all set at zero.
	Second: Note where the pointer points on the scale at the far right of the balance. This is the "zero point" or "balance point." If the pointer is not near the center of the scale, let an instructor know so that we can get it adjusted. If it is off just a little bit, make a note of where it is and weigh to that point.
	Third: Get a weighing dish, weighing paper  or other container.
	Fourth: Put the weighing paper, dish or container on the balance pan and weigh it by the following procedure:
	Move the 100 gram weight to the right one notch at a time until the pointer goes below the balance point.
	Then move it back to the left one notch. Make sure that it is in a notch.
	Next, move the 10 gram weight to the right one notch at a time until the pointer goes below the balance point.
	Then move it back to the left one notch.
	Next, turn the dial until the pointer lines up with the balance point again.
	Fifth: Record the weight of the paper or container. This requires that you add up the weight values shown by both sliding weights and the dial. In this case it is 28.87 g.
	The sixth step is to put the material you want to weigh in the container. Adjust the weights and dial to bring the balance pointer back to the balance point and then record the total weight shown there to the nearest 1/100th of a gram as we just discussed.
	Then seventh: The weight of the material is the difference between the total weight and the weight of the container. It can be obtained by subtracting the weight of the container from the total weight.
	Eighth: The last step is to clean up anything you might have spilled and to return the weights and dial to zero.

I'd like you to go over to the laboratory area and actually use a Dial-o-gram balance.   You can do this now or later when you are in the lab.  Make some weighings to the nearest hundredth of a gram, until you are confident in your ability to do that. There are some objects over there labeled with their weights that you can use. When you are confident, get another sample from the instructor, weigh it to 1/100th gram precision, record its weight in Exercise 9, have the instructor check your work, then continue with the lesson.
