Science
An organized way of gathering evidence about the natural world.
Observation
The act of noticing and describing events or processes in a careful or orderly way. Often using the five senses.
Inference
A logical interpretation based on what scientists already know.
Hypothesis
A scientific explanation for a set of observations that can be tested in ways that support or reject it.
Controlled Experiment
...
Independent Variable
The changed or manipulated variable in an experiment.
Dependent Variable
The Variable that is unchanged and observed in an experiment. Also called the responding Variable.
Control Group
The group exposed to the same conditions as the experimental group except for one independent variable.
Data
Detailed records of experimental observations.
Quantitative Data
Numbers obtained by counting or measuring.
Qualitative Data
Descriptive and involve charecteristics that cannot usually be counted.
Constants
All the factors that remain the same in an experiment.
Repeated Trials
Number of repetitions in which the experiment was done.
Field Studies
Collecting data in nature settings trying not to disturb or interfere with animals while making the observations.
Scientific Method
A procedure that consists of systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
Conclusions
Using experimental data as evidence to support, refute or revise the hypothesis.
Trial and Error Science
The process of experimenting with various methods of doing something until one finds the most successful.
Biology
The study of life
DNA
The information an organism needs to live, grow, and reproduce in a genetic code.
Stimulus
A signal to which an organism responds.
Sexual Reproduction
When cells from two parents unite to from the first cell of a new organism.
Asexual Reproduction
When a single organism produces offspring identical to itself.
Homeostasis
The process of living things maintaining a stable internal environment.
Metabolism
The combination of chemical reactions through which an organism breaks down materials to create energy from the materials it destroys. Photosynthesis is also this.
Heredity
The information coded in DNA the can influence your future.
Evolution
The process of populations adapting and changing over time.
Theory
A well tested explanation that unifies a broad range of observations, laws and many relate to hypotheses from other scientists.
Bias
Favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair.
Cells
The smallest unit considered fully alive. They can grow, respond to their surroundings and reproduce. They make up all life.
