Experiments
Independent Variable
It is the variable changed by the scientist.
Observations of measurement.
Organism
Any living organism.
Cell
Smallest unit of all living things.
Classification
The process of grouping things based on similar characteristics.
Dependent Variable
The variable measured.
Qualitative Observations
Observations with senses.
Producer
Makes its own energy.
Unicellular vs.
Multicellular
An organism made of ONE cell.
An organism made of MANY cells.
Taxonomy
The science of classifying organisms.
Control Variable
Conditions held constant so ONLY the Independent Variable changes.
Inference
Conclusions drawn from observations.
Consumer
Gets energy from other living things.
Cell Theory
It is combined scientific knowledge that states that:
The 8 levels of Taxonomy
“Didn't Know People Could Own Fake Grass Skirts”
Stimulus
Any changer that makes organisms react (like light, temperature; shivering).
Bar Graph
Bars compare data among categories.
Autotroph
Auto means “self”; troph means “feeder” – so autotroph is a producer that makes its own food.
Homeostasis
The maintenance of stable internal conditions. All organisms maintain homeostasis to stay alive.
Binomial Nomenclature
It is a 2 name system that indicates genus and species.
Response
Changes body/behavior (like shivering).
Line Graph
Compares changes over time.
Heterotroph
Hetero means “other” and troph means “feeder” – so a heterotroph is a consumer that can’t make their own food.
Spontaneous Generation
It is an outdated theory that living things come from its nonliving surroundings.
Genus
Species
1st word; group is closely related; group is similar
A group of similar organisms that can mate and have fertile offspring.
