Term
Observation
Definition
step one
Term
For observation, how do you perceive objects or events?
Definition
By employing your five senses
Term
What are inferences basted on?
Definition
prior knowledge rather than on direct observation
Term
The bones are 10cm long. Is this example an inference?
Definition
no
Term
The bones are fragile. Is this example an inference?
Definition
yes
Term
forming a hypothesis
Definition
step two
Term
How is a statement testable?
Definition
if evidence can be collected that either does or does not support it
Term
Forming a hypothesis is only useful when?
Definition
if it can be tested
Term
What must often be done to a hypothesis?
Definition
it must be refined and revised or discarded
Term
What is a statement made in advance that state the results that will be obtained from testing the hypothesis?
Definition
hypothesis
Term
experimenting
Definition
step three
Term
What is experimenting?
Definition
testing a hypothesis or prediction by gathering data under controlled conditions
Term
What is an independent variable?
Definition
what the experimenter uses or changes to produce results
Term
Observations and measurements are taken for a particular factor in both groups. What is this factor?
Definition
dependent variable
Term
What is quantitative data?
Definition
data measured in numbers
Term
What is qualitative data?
Definition
info that isn't numbers
Term
organizing data
Definition
step four
Term
What involves placing observations and measurements (data) in order? (graphs, charts, tables, or maps)
Definition
organizing data
Term
conclusion
Definition
step five
Term
What are made on the basis of facts, not observations?
Definition
conclusions
Term
What are conclusions often drawn or gathered from?
Definition
data or from a study or experiment
Term
What should a conclusion support?
Definition
the hypothesis
Term
What should a conclusion be?
Definition
retestable
Term
communication
Definition
step six
Term
What is the basis of communication?
Definition
Scientists must share the results of their studies with other scientists (peers) and must publish finding in journal.
Term
What may be formed after many related hypotheses have been tested and supported with experimental evidence?
Definition
theory
Term
What is a theory?
Definition
A broad and comprehensive statement of what is thought to be true that is supported by considerable evidence.
Term
What is a statement of fact that concisely explains an action or group of actions?
Definition
Laws
Term
What are laws?
Definition
They are accepted to be true, universal, and may be expressed as a math equation.
Term
Organization is the high degree of order within an organism's internal and external parts. A cell is the smallest unit that can perform all of life's processes.
Definition
Organization and Cells
Term
This is a physical or chemical change in the internal or external environment. Organisms must be able to respond and react to changes in their environment to stay alive.
Definition
Response to Stimuli
Term
The maintenance of a stable level of internal conditions even though environmental conditions are constantly changing.
Definition
Homeostasis
Term
This is the sum of all the chemical reactions that take in and transform energy and materials from the environment.
Definition
Metablolism
Term
All living things grow and increase in size. Development is the process by which an organism becomes a mature adult.
Definition
Growth and Development
Term
All organisms produce new organisms like themselves in this process.
Definition
Reproduction
Term
The ability of populations of organisms to change over time is important for survival in a changing world.
Definition
Change Through Time
Term
What kind of organisms have cells that are specialized to perform specific functions?
Definition
multicellular organisms
Term
Energy use equals what?
Definition
metabloism
Term
What is the sum of all chemical processes?
Definition
metabloism
Term
What is an organism's tendency to maintain a stable internal condition?
Definition
Homeostasis
Term
What are examples of homeostasis?
Definition
Temperature, PH, ect;
Term
Growth and Development
Definition
All living things that grow and increase in size
Term
What is the process by which an adult organism arises?
Definition
develpment
Term
What is the series of changes that an organism undergoes during it's life?
Definition
development
Term
What occurs as the result of cell division and cell enlargement?
Definition
Growth
Term
What is the formation of two cells from a pre-existing cell?
Definition
cell division
Term
What is the process whereby an organism produces more of it's own kind?
Definition
reproduction
Term
Reproduction is not essential to survival of individual but is for what?
Definition
continuation of species
Term
What is it that detects and responds to changes in light, heat, sound, chemical, and mechanical contact?
Definition
Responsiveness
Term
What does the Change Through Time equal?
Definition
Evolve
Term
What does Favorable characteristics that are selected for and passed on to offspring equal to?
Definition
Adaptations
Term
What is the process that enables an organism to better survive in an environment?
Definition
Evolution
