Scientific Process
Information, facts, or data that supports or contradict a hypothesis or theory
What is evidence?
Testable idea or explanation that leads to a scientific investigation
What is a hypothesis?
Descriptive, relating to words- certain attributes, observations, behaviors
What is Qualitative Data?
The repetition of an experiment by other scientists to ensure the validity of the experiment
What is replication?
Group of the same species that live in the same place; field mice in a corn field
What is a Population?
The tested variable that the experimenter changes, or manipulates in the experiment
What is the independent variable?
Group that receives the independent variable (the one test variable that is changed)
What is the tested group?
A piece of information we gather using our senses - sight, hearing, smell, touch
What is an observation?
Examine the quantitative or qualitative data to understand the patterns, trends, and biological relationships in an experiment; compare the outcome with the hypothesis
What is analysis?
An individual or living thing; human, ant, ivy plant
What is an organism?
All factors that are unchanged in the experiment
What is the controlled variable?
Comparing results to their prediction; supporting or not supporting the hypothesis
What is a conclusion?
Scientific investigations do not involve controlling variables. They involve many different scientific methods and include quantitative and/or qualitative observations
What is an investigation?
The condition in which human needs are met in such a way that a human population can survive indefinitely at a standard of living similar to the current one
What is sustainability?
Nonliving parts of the ecosystem including air, water, rocks, light and temperature
What is an abiotic factor?
The group that does not receive the independent variable
What is the control group?
Procedure designed to test an hypothesis under controlled conditions
What is an experiment?
Measurable, relating to numbers- how many, how much, or how often; numerical value
What is Quantitative data?
The greater the demand for a limited supply of something, the more that product is worth
What is the Law of Supply and Demand?
All of the organisms living in an area together with their physical environment
What is an ecosystem?
Repeat the experiment with the independent variable to decrease the chance of errors and increase the reliability of the results.
What is repetition?
The outcome variable is the data that is collected and measured as a result of changing the independent variable in your experimental design
What is the Dependent variable?
The outcome variable is the data that is collected and measured as a result of changing the independent variable in your experimental design
What is a dependent variable?
Ways to express the differences in consumption between nations; shows the productive area of earth needed to support one person in a particular country
What is an Ecological Footprint?
All of the living organisms including animals, fungi, plants, dead organisms, and bacteria.
What is a biotic factor?
