21. We will be using triple-beam balances to find the mass of various objects.
22. How to Use a Triple Beam Balance:
1st – Place your object on the scale.
2nd –Slide the large weight to the right until the arm drops below the line. Move the rider back
one groove. Make sure it “locks” into place.
3rd – Repeat this process with the top weight. When the arm moves below the line, back it up
one groove.
4th – Slide the small weight on the front beam until the lines match up.
5th – Add the amounts on each beam to find the total mass to the nearest tenth of a gram.
