Studied by 8 peoplescience
uses evidence to construct testable explanations and predictions of natural phenomena
observation
the act of noticing and describing events or processes in a careful and orderly way
inference
A logical interpretation based on what a scientist already knows
hypothesis
A scientific explanation for a set of observations that can be tested in ways that support or reject it
controlled experiment
A test of a hypothesis in which only one variable is changed at a time, all others are left the same
independent variable
a variable that the scientist changes
dependent variable
a variable that changes due to the independent variable
control group
a group within an experiment that is exposed to the same conditions except for the changes by the scientist, "testing group"
qualitative data
data descriptive with characteristics
theory
a thought out explanation for observations made
bias
a particular based off of a personal opinion
biology
the study of life
stimulus
any signal in the environment that an organism responds to
cell
the basic unit of structure in all living organisms
DNA
a chemical used by all organisms to store information an organism needs to live, grow and reproduce
sexual reproduction
a method of offspring production by 2 different parents
asexual reproduction
a method of offspring production by one organism
metabolism
the combination of chemical reactions that occur in an organism when they build up or break down material as they utilize energy to grow, develop and reproduce
heredity
The passing of information for traits from one generation of organisms to the next generation
homeostasis
The condition that occurs when an organism keeps their internal environment relatively stable even when external conditions change dramatically
biosphere
all forms of life on earth
evolution
Changes that occur in a group of organisms over time
quantitative data
date specific to numbers
what are the goals of science
components of a scientific methodology
observation, ask questions, hypothesis, experiment, collect data, analyze data, review
independent variable vs. dependent variable
independent variable is the cause and dependent variable is the outcome due to the cause of the independent variable
what is the purpose of a control
to use as comparison in the testing process
hypothesis vs theory
a hypothesis is an assumption before research and a theory is a principle used to explain the data found in research
what are 4 mind habits useful for science
curiosity, skepticism, creativity, and openmindedness
can a theory ever be accepted as proven
what makes science self correcting
the tests prove themselves through experiments
miss
motion, ingestion, secretion, and sensitivity
Redcar
respiration, excretion, digestion, circulation, assimilation, reproduction
MACHI
metabolism, adaptions, cells, homeostasis, information
what system of measurement is used by scientists
metric system
