what is the study of matter and movemet of God´s fisical creation
science
of the three steps of the scientific method which one includes carefull measurement, organization of info, data, and extensive research
observation
what is the method that consist of three mayor steps of observing, hypothesising, and experimenting
scientific method
what is a tentative explanation
hypothesis
what is an artificial enviroment design to test a variable
experiment
what is the term meaning that a hypothesis can be proven false
falsifiable
what does it mean that when a scientist himself receives consistend results
repeability
what is the ability if we have multiple scientist get the same results
reproducibility
which main type of variable is the result of the experiment
dependent variable
what is the variable that i change in the experiment in order to test the dependent
independent
which is the gropup in which the independet variable is absent
control group
what principle states that events observed in the universe has rational causes
casuality
the scope of science is limitted to the study of created matter and energy in the….
precent
what may leat to interpret its data in a way that supports its own political, social, or economic views
bias
what is a conclusion based on reasoning from evidence
inference
what is an statement of fact
proposition
what type of proposition has an if/then statement
hypothetical proposition
what is a form of inference that is made by saying that the antecedent is true therefore the consequent must be true
afirming the antecedent
what form of reasoning has it´s ultimate purpose as to determine cause and effect
inductive reasoning
what is essentially a method of difference where all but one factor is the same in every stuation
method of concomitand variation
what is refered to a beging the question because the conclution logicaly flows the premises but the premises includes the assumption of the conclution
circular reasoning
what is a personal attack
ad hominem
what is a term that is missed leadingly used with two different meanings in a single argument
equivocation
what is a fallacy in argument, based on someones in authority insted of being an facts or reason
argument from the authority
what is the use of science so solve practical problems
technology
what are the minum characteristics that a desing must needs to function at all
criteria
what are any characteristics that are require to solve a problem
constrains
what is given up one characteristic that is less important for a characteristic that is more important
tradeoff
what is a model of the desing used for testing
prototipe
what is anything that provides a partial representation of something else
model
what is described as the substance of the fisical world
matter
what is the property of matter that resist changes in motion
inertia
what is any push or pull
force
what is the ability to do work
energy
what is the amount of matter that an object has
mass
what is the amount of gravitational pull on an object
weight
what is the amount f space that an object has
volume
what is the mass on a certain volume
density
what is the equation for density
p=m/v
what is considered the fourth state of matter
plasma
which state of matter has a definate shape and volume
solid
what is an indirect measurement of an objects thermal energy
temperature
which type of change, changes the identity of a substance
chemical change
which branch of science is the study the interaction between matter and energy
fisics
what is the study of the composition and interactions of matter
chemistry
what branch of academia simes to describe the univers and is the language of science
mathematics
what is an statement that two expresions are equal
equation
what is the closseness of a measurement to an exact value
accuracy
what is the closseness of several measures next to each other

what is a method to make really large or really small numbers more manageable
scientific notation
what is a especific measure to which all other measures are compared to ensure uniformiry
standart of measure
what system of measurement we commonly use in USA
food pound second (FPS system)
what system of measurement was design by french scientis to replace the FPS system
metric system
what is the new form of called the metric system
SI system
metric pre-fix that means 100

celcious
of the three temperature scales is the absolute temperature scale
kalvin
what is a technique used for converting from one set of units to another set of units
dimentional analysis
what is the amount of three dimentional spaces that matter takes up
volume
one method by which i can measure volume
fluid desplacement, actual meassurements, and geometric formuas
what is the ratio of the density of a substace to the density of a standart
specific gravity
