4. Metric Measurement With your group fill out the K and W sections of the chart below.

5. Determine with your group: Do you know what I am saying?
I am 5 2 (read: five two)
When I was born I was 10 2 (Read ten two)
I am about 36.8
When I was born I was 57.15
What is my point?

8. School Mission Statement
Mission Statement: Renton High School aims to provide effective instruction and support services to enable students to acquire 21st century skills, develop international mindset, enhance knowledge, and nurture the ability to make thoughtful decisions. Our students will graduate:
-on-time,
-empowered to be successful in a college, technical or professional program,
-prepared to compete in the global workforce, and
-ready to serve our pluralistic community.

9. Metric Units Length/Distance: mm, cm, m, km Volume: mL, L, cm3
Mass: mg, g, kg
Temperature: ˚C

10. Metric BONUS!!! All units are base 10! 1000 milligrams = 1 gram
100 centimeters = 1 meter
1000 g = 1 kilogram
1000 m = 1 kilometer
This means when you do conversions you only have to know how to move decimals!

11. Significant figures in measurements

12. Do Now Pick up yellow packet Turn in homework (interview of an adult)
Take out notes

13. Significant Figures
Significant figures (sig figs)- digits that we know for sure plus one estimated digit.

14. When using electronic measuring tools:
Read the # right of screen
Shows a Mass of g. The
this has 4 sig figs.
If the mass read 3.24 g
than it would be 3 s.f.

15. When using manual measuring tools:
You must estimate one
extra digit than you know
for sure.
Top ruler shows 1
decimal so you estimate
a 2nd. (3 sig figs here)
Bottom Ruler shows none
so you estimate 1. (2 sig figs here)

16. When using manual measuring tools:
Graduated cylinder
Marking every mL.
Record volumes with
1 decimal place.
Ex: What is this volume?

17. How many sig figs does this number have?
No decimal:
Everything EXCEPT 0’s at the end
(4100  2 sig. fig.’s)
Decimal:
Everything EXCEPT 0’s at the beginning (  2 sig. fig.’s)
(1000.  4 sig. fig.’s)
(  5 sig. fig.’s)

18. How many sig figs does this number have?
If the number is in Scientific notation:
Everything before the x 10something
(1.540 x 1017 4 sig. fig.’s)
(1.2 x 1024 2 sig. fig.’s)

19. Count the sig. fig.’s:
200
200.
200.00
2.000 x 1014
200.01 1 3 5 4 5 1

20. Measurement Activity
Split up and go into the lab and make the required measurements. Use the correct # of sig figs.
Don’t put anything heavier than a beaker on the small scale.
Check your results with me.
Share your results with your group.

21. Estimation:
Now that you have made measurements use those to make predictions about: a. temperature outside in December. b. Temperature of boiling water. c. Length of the room. d. Mass of a full can of soda. e. Volume of a full can of soda f. Distance from here to Coulon beach. Write a full prediction: Ex: I think my wingspan is about 1.5 meters because I measured the width of the lab bench to be almost 1.4 meters and my wingspan is a little longer than that.

22. Do Now 10/9/14
Which metric unit would be most appropriate for measuring the following?
Mass of a couch (sofa):
Length of a outdoor play field:
Temperature of the ocean:
How many significant figures do the following numbers have?
4.800
72000
