When I was born I was 10 2 (Read ten two)

I am about 36.8

When I was born I was 57.15What is my point?

What do you think the color coding means?Dark Countries-Light Countries-

According to a CIA 2007 reportSchool Mission StatementMission 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.

Metric UnitsLength/Distance: mm, cm, m, kmVolume: mL, L, cm3Mass: mg, g, kgTemperature: CMetric BONUS!!!All units are base 10!1000 milligrams = 1 gram100 centimeters = 1 meter1000 g = 1 kilogram1000 m = 1 kilometer

This means when you do conversions you only have to know how to move decimals!Significant figuresin measurementsSignificant FiguresSignificant figures (sig figs)- digits that we know for sure plus one estimated digit.

When using electronic measuring tools:Read the # right of screen

Shows a Mass of 42.03 g. The this has 4 sig figs.

If the mass read 3.24 gthan it would be 3 s.f.

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)

When using manual measuring tools:Graduated cylinder Marking every mL.Record volumes with1 decimal place.

Ex: What is this volume?

How many sig figs does this number have?No decimal:Everything EXCEPT 0s at the end (4100 2 sig. fig.s)

Decimal:Everything EXCEPT 0s at the beginning (0.0032 2 sig. fig.s) (1000. 4 sig. fig.s) (1.0003 5 sig. fig.s)

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)

Count the sig. fig.s:

Measurement ActivitySplit up and go into the lab and make the required measurements. Use the correct # of sig figs.

Check your results with me.

Share your results with your group.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 sodaf. 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.
