Scientific Method And Lab Saftey Vocabulary Flashcards
Observation
the process of collecting evidence
Control
the thing that does not change in an experiment
Measuring
to quantify something (how long, how much, how large)
Variable
the part of the experiment that may change or vary
Flammable
Capable of catching fire
Corrosive
to wear away or be destroyed gradually
Question
to ask
Procedure
the steps to complete an experiment
Classifying
the act of putting like things together
Inferring
a logical conclusion based on what you know
Communicating
sharing results in an understandable way
Conclusion
the end of the scientific investigation
Hypothesis
a tentative explanation for an observation or
phenomenon; an if then statement.
Experiment
a test, trial,or tentative procedure; an act or operation for the purpose of discovering something unknown.
Prediction
an expectation of what will be observed or what will
happen.
Problem
what you are trying to solve in a scientific investigation.
Solution
to answer a scientific investigation.
Observation
the act of noting and recording an event, characteristic or anything detected.
measure
to use a tool to learn more about the volume, length or weight of an object (related word: measurement)
measurement
the collection of data (such as mass, volume, temperature, etc.) described by a standardized unit (such as kilogram, liter, degrees Celsius)
observation
the act of watching over something or taking notice; in science, observations are carefully recorded as part of the scientific process
inference
the process of reasoning by drawing a logical conclusion based on factual evidence
classify
to group things based on similar characteristics (related word: classification)
communicate
to give and receive information (related word: communication)
investigate
to examine or ask questions in an organized way; to learn about something (related word: investigation)
experiment
a series of steps used to figure out the effects of a certain factor on another factor; one way of testing a hypothesis (related word: experimental)
hypothesis
a testable explanation for a problem or phenomena
control
a part of an experiment that is used as a standard to compare experimental observation; it is treated the same as the other samples except that it is not exposed to the manipulated variables; controlled variables in an experiment are all the variables tha (it was cut off originally)
variable
a quantity or condition that can be changed in an experiment (related term: vary, variation)
dependent variable
a factor, trait, or condition that is affected when another factor, trait or condition is changed in a scientific experiment
independent variable
in an experiment that is a fair test; the variable that a scientist changes
solution
a mixture in which a solid and a liquid or two liquids are mixed so evenly, that it is not possible to see the separate particles
conclusion
process of arriving at an inference, interpretation, or reason
accuracy
how close a value is to the true value; in science, it is important to take accurate measurements
precision
1) the exactness of a measurement; 2) the degree to which the results of an investigation show the same results
trials
the act of undergoing testing
metric system
a system of measurement based on multiples of 10
data
recorded measurements or observations collecting during a scientific investigation
predict
to guess what will happen in the future (related word: prediction)
quantitative data
information or data that is based on quantities obtained using a quantitative measurement process
qualitative data
qualitative information records qualities that are descriptive, subjective or difficult to measure
x-axis
The line on the graph that runs horizontally (left-right) through zero; the independent variable is always graphed on the x-axis
y-axis
The line on the graph that runs vertically (up-down) through zero; the dependent variable is always graphed on the y-axis
