13. You can convert between SI units like you can between dollars and dimes.
Units of Length
km = 1,000 m
1 m = 100 cm
1 m = 1,000 mm
1 cm = 10 mm

FAHRENHEIT

19. Balance measures weight
What does is measures?
Balance measures weight

20. Graduated cylinder measures volume
What does is measures?
Graduated cylinder measures volume

21. Meter stick and rulers measures length
What does is measures?
Meter stick and rulers measures length

22. Area vs Volume
Area = length x width
Length is the Long side
98 cm2

23. Volume= length x width x height
Area vs Volume
Volume= length x width x height

24. Measuring Temperature
You measure temperature in degrees Celsius
You use a thermometer
Find temperature by counting the marked lines

25. Which thermometer shows 68 degrees Celsius?
Thermometer Practice
Which thermometer shows 68 degrees Celsius?

26. Measuring Mass
How to read a balance
movie clip!

27. Measuring Mass
A double pan balance has two arms so you will have two reading
The top arm counts by single grams (down to tenths)
The bottom arm counts by 10’s

28. Mass of Substance in Container
Find the Combined Weight
Find the mass of the Container
Subtract the Container from the Combined Weight
You are left with the Substance Weight

29. Measuring: Liquid Volume
Volume is measured in Liters
Measure with a graduated cylinder

30. Meniscus Meniscus is the curved surface in the liquid
You must read it at eye level at the bottom of the meniscus

31. What is the volume of the liquid?
Meniscus Practice
What is the volume of the liquid?

32. Meniscus Practice 53 mL Bottom of meniscus is at 53 mL
Top of the meniscus is at 54 mL
53 mL

33. Volume of an Object Find the Liquid Volume
Put the object in and find Combined Volume
Subtract the Liquid Volume from the Combined Volume
You are left with Object Volume
