Chemistry Test 1

Scientific Method 1)Make Observations 2)Form a Hypothesis 3)Perform a controlled experiment 4)Analyze data 5)Form a theory
Hypothesis reasonable explanation for a series of events
Control factor that stays the same
Variable factor that changes
Independent Variable factor that you are testing
Dependent Variable factor you measure/data
Theory reasonable explanation for a series of events that have been tested
Base units a unit of measure that is based on an object in the physical world
SI units International system of Units
The base units -mass-kilogram kg -length-meter m -electric current-ampere A -amount of substance-mole mol -luminous intensity-candela cd -time-seconds s -temperature- kelvin K
Derived Units Units of measurement composed of two or more base units
3 Base Units volume: meters cubed cm^3 density: mass per volume g/cm^3 speed: meters per second m/s
Weight vs. Mass Mass is a constant measurement in grams and weight varies based on gravitational pull measured in Newtons
Precision vs. Accuracy how close measurements are to a true value while precision is how close measurements are to each other
kilo 1000
milli 1/1000
centi 1/100
