◉ Observation. Answer: the act of noting and recording something
with instruments.
◉ Hypothesis. Answer: a tentative explanation for an observation or
scientific problem that can be tested by further investigation.
◉ Experiment. Answer: a test under controlled conditions that is
made to demonstrate a known truth, examine the validity of a
hypothesis, or determine the efficacy of something previously
untried.
◉ Independent Variable (Manipulated). Answer: variable whose
value is being altered to bring a change in some condition
◉ dependent variable (or responding variable). Answer: dependent
variable (or responding variable) - the observed variable in an
experiment or study whose changes are determined by the presence
or degree of one or more independent variables
,◉ Controlled Variable. Answer: a sample in which a factor whose
effect is being estimated is absent or is held constant, in order to
provide a comparison.
◉ Conclusion. Answer: a position reached after consideration of
data obtained from an experiment
◉ Qualitative Data. Answer: data described in terms of some quality
or categorization that may be informal or may use ill-defined
characteristics such as warmth and flavor
◉ Quantitative Data. Answer: data described in terms of quantity
and in which numerical values are used.
◉ Mass. Answer: a property of matter equal to the measure of an
object's resistance to changes in either its speed or direction of its
motion. The mass of an object is not dependent on gravity and
therefore is different from but proportional to its weight.
◉ Volume. Answer: the amount of space occupied by a three-
dimensional object or region of space
◉ Length. Answer: the measurement of the extent of something
along its greatest dimension
, ◉ Temperature. Answer: a measure of the average kinetic energy of
the particles in a sample of matter, expressed in terms of units or
degrees designated on a standard scale
◉ Metric System. Answer: a decimal system of units based on the
meter as a unit length, the kilogram as a unit mass, and the second
as a unit time.
◉ Scientific Notation. Answer: a method of writing or displaying
numbers in terms of a decimal number between 1 and 10 multiplied
by a power of 10.
◉ Dimensional Analysis. Answer: a technique that involves the study
of dimensions of physical quantities
◉ Significant Figures (Sig Figs). Answer: All of the numbers in a
measurement that are know to be accurate, plus one that is
uncertain.
◉ Bar Graph. Answer: Example:
A 2nd grade class wants to show the class distribution of different
eye colors
◉ Cosomograph. Answer: creates an image of the movement or flow
of materials/resources, contrasting the source with the destination
