3. Measuring Mass Practice Measure the mass of the objects to the nearest gram using a triple beam balance. Name of Object Mass of Object (g) #1 #2 #3 #4

4. 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.

5. 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.

22. Scientific Notation Notes

23. 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 10 23 + 3.2 x 10 22 6.02 x 10 23 + 0.32 x 10 23 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 10 23

24. Multiplying/Dividing Scientific Notation 1.Multiplication – multiply numbers and add exponents 5.0 x 10 3 x 2.0 x 10 4  10 x 10 7 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 10 8 Ans. #2 = 1.20 x 10 -4

25. Writing Scientific Notation from Decimal Numbers

26. Suggest Numbers What is the distance to the sun? How much does your favorite basketball player make in year?
