Triple Beam Balance Analysis Questions Part A. Labeling a Diagram • Label the following parts of the triple beam balance shown below: beams, riders, pan, indicator/zero mark, balance nut, and pointer.

Part B. Short Answer Questions *Answer the following questions using complete sentences. 1. What is the largest total mass that you can measure in grams using a triple beam balance? 2. What are three things that you need to do when preparing your triple beam balance for use? 3. Why do you need to “zero” your triple beam balance before you place on object on the pan to measure? What could happen to the accuracy of your measurements if you do not? 4. Think back to the measuring mass activity during today’s class. Which object had the largest mass in grams? What was the mass in grams? 5. Think back to the measuring mass activity during today’s class. Which object had the smallest mass in grams? What was the mass in grams? 6. What was the easiest part of using the triple beam balance? What was the most challenging part?

Scientific Notation Notes

Adding/Subtracting Scientific Notation 1. Convert all numbers to the power of the largest number. If you make an exponent larger by 1, you must make the number smaller by moving the decimal and vice versa. 6. 02 x 1023 + 3. 2 x 1022 6. 02 x 1023 + 0. 32 x 1023 2. Do the math to the numbers (don’t forget sig. figs. !) 6. 02 + 0. 32 = 6. 34 3. Simplify Number (must be between 1 and 10) if needed. Ans. 6. 34 x 1023

Multiplying/Dividing Scientific Notation 1. Multiplication – multiply numbers and add exponents 5. 0 x 103 x 2. 0 x 104 10 x 107 2. Division – divide numbers and subtract exponents 4. 80 x 10 -6 / 4. 00 x 10 -2 1. 20 x 10 -4 3. Simplify Number (must be between 1 and 10) if needed. Ans. #1 = 1. 0 x 108 Ans. #2 = 1. 20 x 10 -4

Writing Scientific Notation from Decimal Numbers
