Metric units and what they mean to you…

3. What Is Measurement?
A record of an observation that cannot be made by the five senses alone
Usually made with the use of an instrument

4. 5 Major Types Of Measurement

5. Length Length: the distance between 2 points Use A Ruler
or A Meter Stick

6. Every measurement has a common unit of measurement that accompanies it

7. What Are Those Markings??
Millimeters
Centimeters

8. Mass Mass: the amount of matter in a given object
We use a BALANCE to measure mass

9. UNITS
Every measurement has a common unit of measurement that accompanies it
Grams (g)
Mass =

10. VOLUME 3 Ways to Measure Volume
VOLUME: the amount of space an object takes up
3 Ways to Measure Volume
If it’s a regular solid, use the mathematical equation:
volume =
length x width x height
2. If it’s a liquid, use a graduated cylinder
3. If irregular, use the displacement method

11. cubic centimeters (cm3)
More units?
Yes, more units…
milliliters (mL)
Liquid Volume =
cubic centimeters (cm3)
Solid Volume =

12. Water Displacement 3 Steps Take an initial volume of the
water in the graduated cylinder
2. Place the object in the water
3. Observe the new volume and subtract the initial volume from the new volume

13. You Try!!! Final Volume = 9.8 mL - Initial Volume = 8.8 mL
Volume of Object = 1.0 mL

14. It’s Getting’ Hot In Herre…
Temperature: average kinetic energy of an object
We measure this with the usage of a thermometer, but what type of thermometer????

15. Or Degrees Fahrenheit (oF)
Are We There Yet??? YES!!
More Units!!!!
Degrees (Celcius)
Temperature =
Or Degrees Fahrenheit (oF)

16. TIME
Measurable period during which something happens
timeline
clock

17. Units
Seconds
Mya (millions of years ago)

18. Rounding
When you measure or calculate a number with a decimal you should round.

19. What does it mean to round your number to the
Nearest tenth = one number past the decimal
Nearest hundredth – second place past the decimal
Nearest thousandth – third place past the decimal

20. Nearest Nearest Tenth Thousandth
= __________ _________
= ________ ________
3.7
3.655
10.4
10.432

21. Metric System
meter
liter
gram

22. 1mm = _____ cm 10 mm = ____ cm 1 km = _____ m 0.1 1.0 1000

23. 0.9 cm
4.3 cm
