39. Measurement Tools 1. Name: Triple Beam Balance Measurement: Determine the mass of a substance Units: grams (g)

40. *Important Reminder! • A triple beam balance has three separate lines (it’s like adding three rulers together)-you must ADD each of the lines together!

41. Practice! What is the mass of the unknown object?

42. Steps 1+2 Step #1: • Make sure all riders are placed at zero (on the far left). The white line on the black arm should be level with the zero mark on the right side of the balance. Step #2: • Move the rider on the middle beam (largest mass) to the right to the last notch before the arms dips down. When the white line on the arm dips below the zero mark, move the rider back one notch to the left.

43. Steps 3+4 Step #3: • Move to the next-largest rider (back beam) to the right. Move it to the last notch before the arm dips down. When the white line on the arm dips below the zero mark, move the rider back one notch to the left. Step #4: • Slide the smallest rider (front beam) to the right. Slide it until the white line on the arm dips below the zero mark. When the white line on the arm dips below the zero mark, slide the rider back to the left.
