4. Follow these steps when finding the mass of an object...
1. With nothing on the tray move all of the sliders to the zero position and make sure that the pointer is lined up with the zero mark.
2. Place the object on the tray and adjust the sliders as described in the picture above until the pointer is lined up with the zero mark again.  (Note: When the back two sliders are in a correct position they will be locked in one of the notches on the beam.)
3. Add the values that the three sliders are pointing at to determine the object's mass. 

5. 1. What is the mass of the object on the balance?

6. 2. What is the mass of the object on the balance?

7. 3. What is the mass of the object on the balance?

8. 4. What is the mass of the object on the balance?
