Ready for the CELEBRATION yet??

Finally, we are very close to the ending of this chapter which was all about number and value. And now, we are going to have a test on Chapter 3 on MONDAY, NOVEMBER 15th!

Materials will include:
Significant Figures, Measurement & Uncertainty, Scientific Notation, Density, Graphing, Lab 2E, and Unit Conversions! Bring a scientific calculator! Know all formulas for Volume, Area, Density, and Percent Experimental Error.

Approximately 10 Written and 40 Multiple Choice Questions for a total of about 70 marks!!

Did you get them ALL??? Wasn't it a piece of cake?
well, that didn't cover the whole chapter. I will leave it to your own to study for calculation involved in Lab 2E (Thickness Calculation) and graphing.

GOOD lUCK STUDYING ALL!~
