New cards
science
uses evidence to construct testable explanations and predictions of natural phenomena
2
New cards

the act of noticing and describing events or processes in a careful and orderly way
3
New cards
inference
A logical interpretation based on what a scientist already knows
4
New cards
hypothesis
A scientific explanation for a set of observations that can be tested in ways that support or reject it
5
New cards
controlled experiment
A test of a hypothesis in which only one variable is changed at a time, all others are left the same
6
New cards
independent variable
a variable that the scientist changes
7
New cards
dependent variable
a variable that changes due to the independent variable
8
New cards
control group
a group within an experiment that is exposed to the same conditions except for the changes by the scientist, "testing group"
9
New cards
qualitative data
data descriptive with characteristics
10
New cards
theory
a thought out explanation for observations made
11
New cards
bias
a particular based off of a personal opinion
12
New cards
biology
the study of life
13
New cards
stimulus
any signal in the environment that an organism responds to
14
New cards
cell
the basic unit of structure in all living organisms
15
New cards
DNA
a chemical used by all organisms to store information an organism needs to live, grow and reproduce
16
New cards
sexual reproduction
a method of offspring production by 2 different parents
17
New cards
asexual reproduction
a method of offspring production by one organism
18
New cards
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
19
New cards
heredity
The passing of information for traits from one generation of organisms to the next generation
20
New cards
homeostasis
The condition that occurs when an organism keeps their internal environment relatively stable even when external conditions change dramatically
21
New cards
biosphere
all forms of life on earth
22
New cards
evolution

23
New cards
quantitative data
date specific to numbers

New cards
what are the goals of science
25
New cards
components of a scientific methodology
observation, ask questions, hypothesis, experiment, collect data, analyze data, review
26
New cards
independent variable vs. dependent variable
independent variable is the cause and dependent variable is the outcome due to the cause of the independent variable
27
New cards
what is the purpose of a control
to use as comparison in the testing process
28
New cards
hypothesis vs theory
a hypothesis is an assumption before research and a theory is a principle used to explain the data found in research
29
New cards

30
New cards
can a theory ever be accepted as proven
31
New cards
what makes science self correcting
the tests prove themselves through experiments

metabolism, adaptions, cells, homeostasis, information
35
New cards
what system of measurement is used by scientists
metric system
