A.1 Measurement and the Metric System (p.6)
1. A modernized form of the metric system was internationally adopted in .
2. (Circle T - F ) This measurement system, call SI, is now used by every recognized scientist worldwide.
Questions 3-8 refer to the picture at the right,
from p.6 in your text.
3. Object #1 is a beaker with graduated markings
to approximately measure and hold liquid
volumes. What are the numbers and names of
two other numbered items which more
accurately measure volume?
4. What are the numbers and names of items
a. mass? #
b. weight? #
c. A scale and a balance weigh and mass
differently. Which one uses a spring?
5. Which object is concerned with angles (degrees)
6 a. Which object is concerned with degrees (but
b. What is this metric degree?
7. a. Which objects could measure the diameter of a quarter?
b. Which would do it more accurately? #
8. (Circle T - F ) There is a measuring device shown to measure every measurable unit. (length, volume,
mass, temperature, time, and angle)
9. a. A meter is a little than a yard stick.
b. To measure smaller objects, we divide a meter into parts for cm.
c. Even smaller objects can be measured in which is 1/1000 m.
10. The distance across your fingernail is about 1 cm. What are the approximate dimensions of and audio
cassette in cm. (l x w x h)?
x x = c.c. (cm3 )
11. Your waist is about 1 meter (m) from the floor. A box which is 1 m3 would most approximately hold
a (bicycle - tricycle - basketball) with a little space left over.
12. a. A liter is a little larger than a (pint - quart - gallon) and a little less than 3 cans of pop.
b. If we divide a liter into parts, we have useful chemistry volume unit called mL.
13. There is an important connection between c.c (cm3 ) and mL. How does 1 c.c. compare in volume to 1 mL?
Your Turn: I.1 p.6
1. A penny diameter = mm = cm A nickel diameter = mm = cm
A quarter diameter = mm = cm A dime diameter = mm = cm
2. cc = mL = L = sugar cubes
3 a. Only U.S. customary volume units? What are they?
b. Both U.S. and S.I. units. Include volumes.
4 a. One SI system advantage
b. One SI system disadvantage
