Unit 3: Measurement, Percent Composition/Emp. Formula,

What is the difference in the precision of a beaker and a graduated cylinder? Why is one preferable to the other if accuracy is the goal? How do you convert from one unit to another? What does it have to do with compounds? How do chemists know how much of anything is in a compound?

 Explain 1/10th the finest unit in measurement & how this aligns with significant digits and the ideas of accuracy/precision
 Appropriately convert units utilizing factor label
3.1a What's in a BB?
Exploration Objective

3.1b Numeracy & Measurement
Measurement is important in the lab; it influences the validity of data and calculations. Measurements, though, have limitations in precision and accuracy. The Prezi below is a quick review and reminder of the lessons and ideas you should understand about measurement.

3.2a Thickness of Al Foil
Exploration Objective

3.2b Factor Label
These notes are a followup to what you took in class. Remember the point of factor label: to be able to convert any unit to any other through 'crosscanceling' units (i.e., using conversion factors and ratios).
