1. Measurement
& Metrics

2. 10-14-13 Do Now: How Do You Measure Up?
Key Question: What does Volume and Mass measure? Initial Thoughts: Get out your glue stick, too.

3. Evidence 1: Notes & Practice

4. SI Measurements (also known as “metric system”)
“SI” stands for “System International” or “International System of Measurement”

5. SI Measurements (also known as “metric system”)
What about it?
Common Language for scientists
Based on units of 10
Multiply or divide to go up or down when converting units
Prefixes determine “how much” of a unit

7. SI Measurements (also known as “metric system”)
Important BASE units to remember:
METERS = m (measures distance or length)
Measure with ruler/meterstick

8. LITERS = L (measures volume — how much space something takes up)
Measure with graduated cylinder/beaker
Or with a ruler (length x height x width)

9. GRAMS = g (measures mass)
Measure with triple beam balance/scale

10. oCELSIUS = oC (measures temperature)
Measure with thermometer

11. BASE UNIT (liter, meter, gram)
Important PREFIXES to remember:
k = kilo- (means “1000”)
h = hecto-(means “100”)
D = deca-(means “10”)
BASE UNIT (liter, meter, gram)
d = deci-(means “1/10” or 0.1)
c = centi- (means “1/100” or .01)
m = milli- (means “1/1000” or .001)

12. Kids Have Dreams But Cost Money

13. Prefixes K H D base unit d c m Weight of an elephant? An ant?
Kilo Hecto Deca meter deci centi milli liter grams Large Medium Small
Weight of an elephant? An ant?
Fly length? Distance to Disneyland? Length of finger?
Volume of a pool? Amount of juice in a pitcher?
Elephant = kg, ant=mg
Fly length = mm, disneyland = km, finger=cm
Volume of pool = kl, juice in a pitcher = l

14. Practice 1 meter (think meter stick) Equals 100 cm Equals 1000mm
Challenge: How many kilometers?
1 meter Equals 1/1000 km

16. Evidence contd.
With your table partner, complete the bottom questions 1-10.
Reminder: remember Participation. Everyone should be contributing.

17. Evidence 2: Measurement Lab
There are 8 stations. Read the instructions and record your answers in your journals. MAKE SURE TO WRITE DOWN THE NUMBER OF THE STATION

18. Measuring Liquids How many ml of water is shown in the picture?
Always measure from the bottom of the meniscus.
Answer: 6.6 ml

19. Measuring VOLUME by displacement
Used to measure irregular or non-box shapes.
When you can’t measure length x height x width
5.6 – 4.8 = 0.8 ml

20. Measuring Mass
What is the mass? Don’t forget to include units!!!

21. Analysis Questions
Name 2 different base units that could measure the amount of water a fish tank could hold.
Why is the number 10 important in the metric system?
Why would the prefix “kilo” be more useful than “tera” (1 trillion)?

22. Summary Remember: paragraph format
What did you think about how volume, mass, and length are measured before this lesson? What did you learn about how volume, mass, and length are measured from this lesson? (Minimum of 3 sentences!!!) What are some further thoughts or questions you have about how volume, mass, and length are measured?

23. Reflection: Come up with your own Metric Mnemonic:
i.e. Kids Have Dreams But Dreams Cost Money
Kilo Hecto- Deca (BASE) Deci Centi Milli- OR
King Henry Doesn’t Usually Drink Chocolate Milk
Kilo Hecto- Deca (unit) Deci Centi Milli-

24. Big Idea What is the big Idea of metric units & conversion?
Metric prefixes are multiples of 10 and can be easily converted by moving the decimal.
