basic unit = meter
use rulers and meter sticks

9. Approximate Length Measurements (write 2 examples on your paper)
Thickness of dime = 1 millimeter
Width of a large paper clip or your fingernail = 1 centimeter
Width of a doorway = 1 meter
Six city blocks or 10 football fields = 1 kilometer
1 mile = 1.6 kilometers

Today I will answer……What’s the correct measurement?

17. ALWAYS use the cm/mm side…..
Look at your ruler
ALWAYS use the cm/mm side…..
Never inches!!

18. Lines in between = millimeters
Look at your ruler
1-30 = centimeters
Lines in between = millimeters

19. Look at your ruler & meterstick
Count the lines between 1 & 2
1 cm = 10 mm!

20. What is the DIFFERENCE in mass from the TBB 1 & 2?

21. What is the DIFFERENCE in mass from the TBB 1 & 2?
354.6 g – 325 g
29.6 g

22. #3 - Volume
the amount of space (capacity) an object occupies
basic unit = liter, cm3
use graduated cylinders, beakers, and rulers

23. Approximate Liter Measurements (write 2 examples on your paper)
one drop = 1 milliliter
1 liter= half of a 2 liter soda bottle
500 2-liter bottles of soda = 1 kiloliter

24. A. Solid Volume
basic unit = cm3
ruler
Length x width x height

25. What’s the volume??
6 cm x 5 cm x 10 cm = 300 cm3

26. What’s the SOLID volume of???
1. Post-its: _______ cm3
Length = _____ cm
Width = _____ cm
Height = _____ cm

27. B. Liquid Volume basic unit = liter (L) graduated cylinders
read the bottom of the meniscus

28. 23
23 WHAT?
23 mL

29. 53
53 WHAT?
53 mL

30. What’s the REGULAR volume of???
1. Filled cup of water: _______mL

31. C. Irregular Volume basic unit = 1 mL = 1 cm3 graduated cylinder
Water displacement method
Intervals = 0.1, 0.2, 1, 2 or 10 mL

32. What’s the volume of the rock??
Initial Reading = 200 mL
Final Reading = 260 mL
260 mL – 200 mL = 60 mL
60 mL = 60 cm3

33. Water Displacement Initial Reading of meniscus 4.8 mL
Irregular Object dropped in GC
Read “new” meniscus
5.6 mL
Subtract the “new” from initial reading
Irregular object volume = 0.8 mL
0.8 mL = 0.8 cm3

34. #13 – What the volume of the dinosaur?
Initial Reading of meniscus
4.8 mL
Read “new” meniscus
5.6 mL
Subtract the “new” from initial reading
Irregular object volume = 0.8 mL
0.8 mL = 0.8 cm3

35. What’s the IRREGULAR volume of???
1. Filled cup of water with 2 marbles: _______mL
______ mL = _______ cm3 3

36. Time
a measure of duration
basic unit = seconds
