Front Back
accuracy
 
•  the difference between a measurement and its accepted value
conclusion
 
•  the explanation of the results of an experiment as it applies to the hypothesis being tested
control
 
•  scientific experiment:  a standard to which the results are compared
•  often necessary in order to draw a valid conclusion
•  ensures a fair test
controlled experiment
 
•  an independent variable is the only factor that is allowed to be adjusted, with the dependent variable as the factor that the independent variable will affect
dependent variable
 
•  experiment:  the factor that changes in response to a change in the independent variable
extrapolation
 
•  to estimate the value of a quantity that falls outside the range in which its values are known
hypothesis
 
•  to predict the outcome of an experiment
•  a testable proposal used to explain an observation

"If... then..." statement
independent variable
 
•  experiment:  the factor that is selected or adjusted to see what effect the change will have on the dependent variable
interpolation
 
•  the estimation of a middle value by reference to known values on each side
observation
 
•  the process of watching something or someone carefully to find information / see changes / etc.
precision
 
•  the accuracy to which a calculation is performed, indicated as a specific value
prediction
 
•  a forecast about what you expect to observe when you do an investigation
principle
 
•  a theory, rule or natural / scientific law
procedure
 
•  a method of way of doing something, especially the usual / expected way
scale
 
•  a series of marks at fixed intervals used as a reference standard in measurement
scientific literacy
 
•  the knowledge and understanding of scientific concepts and processes required for personal decision making, participation in civic and cultural affairs, and economic productivity
slope
 
•  the direction of a line on a graph
•  calculated by determining the ratio of rise
                                                               run

horizontal = zero
slanting up = positive
slanting down = negative
uncertainty
 
•  greater accuracy of measurement for one observable variable entails less accuracy of measurement for another
validity
 
•  establishes whether the results obtained meet all of the requirements of the scientific research method
variable
 
•  a factor that can influence the outcome of an experiment
Venn diagram
 
•  a graphical illustration of the relationship between various sets of data
