BEAT Chemistry! (BE Able To): Measurement and Calculations

Distinguish between accuracy and precision

Use correct scientific notation

Convert between various measurements using the metric
system. Be familiar with the prefixes: kilo-, deci-, centi-, milli-,
micro-, and nano-

Count how many significant figures there are in any given
measurement

Do calculations to the correct number of sig figs
 addition/subtraction
 multiplication/division

Make measurements with lab equipment to the right precision
 balance
 graduated cylinder(s)
 ruler

Perform calculations using dimensional analysis (factor labeling)
to keep track of your units

Do density calculations and use d=m/v to solve for either d, m,
or v

Describe the labs you performed this unit and what the key
concept/learning was from each lab
