Units of Measurement & Drawing Conclusions Flashcards
Length/Distance measured in
Meters (m)
Mass measured in
Grams
Volume measure in
Liters (L)
Converts one unit of measurement to another
Dimensional Analysis
Converting from Meters to Centimeters
Length in Centimeters=Length in meters x 100
Convert liters to milliliters
Volume in milliliters=Volume of liters x 1000
Measured with ruler, meter stick or tape measure
Length/Distance
Measure with graduated cylinder or volumetric pipette
Volume
Use balance to measure
Mass
Measured by amount of matter within object
Mass
Measured by the amount of space that is taken up by object
Volume
If mass of object is very large use
Kilograms instead of Grams
If mass of an object is very small use
Milligrams or Micrograms
If length of an object is very large use
Kilometers or Miles
If length of an object is very small use
Nanometers or Picometers
Information that is gathered through observation and experiment
Empirical Evidence
Quality or characteristics
Qualitative
Quantity or amount
Quantitative
Scientists collect data by repeating experiments with the same ______ and procedures previously preformed
Variables
Experiments are consistent with each other
Reproducible Results
If results cannot be reproduced something is _____ with the experiment and it must be ______
Wrong; Repeated
In order to make confident conclusions about the results of a conclusion, scientists must use
Empirical Evidence
Something that produces an effect
Cause
The result of a cause
Effect
In order for scientists to identify cause and effect relationships they must use
Empirical Evidence
