Biology

Biology

The scientific study of life. Biology. Biology is the branch of science that explores living organisms and their interactions with the environment.

Control

The standard used for comparison of test results in an experiment. A control is a part of an experiment that is not changed so you can compare how other parts change.

Data

Information gathered through observation. Data. In Science, data is the raw facts and figures collected during experiments or research to analyze and draw conclusions.

Dependent variable

The factor measured at the end of an experiment. Dependent variable. In science, a dependent variable is what you measure to see the effect of changes in the experiment.

Evolution

The change in a species over time. Evolution. Evolution is the process by which living organisms develop and diversify from earlier forms through gradual changes over generations.

Experiment

Testing a hypothesis by collecting data in controlled conditions. Experiment. An experiment is a test where scientists change something to see what happens.

Homeostasis

The maintenance of the stable internal conditions in an organism. Homeostasis. It is how living things keep their internal environment balanced, like keeping a constant body temperature.

Hypothesis

A possible explanation or answer to a scientific question. Hypothesis. A hypothesis is a testable idea or prediction about how something works that can be verified through experiments.

Independent variable

The variable which is manipulated by the researcher. Independent variable. In Science, the independent variable is the one that is changed to observe its effect on other variables.

Inference

A logical assumption based on prior experience. Inference. In science, inference is when you make a conclusion based on evidence and reasoning.

Metabolism

The sum of all chemical reactions in an organism. Metabolism. Metabolism is how your body converts food into energy and building blocks for growth, repair, and maintaining life.

Observation

The process of using your senses to gather information. Observation. In science, observation is the act of noticing and describing events or processes in a careful, systematic way.

Organism

Any living thing. Organism. An organism is a living being that can grow, reproduce, and respond to its environment.

Reproduction

The process of making offspring is called reproduction. Reproduction is how living things make new generations to continue their species.

Science

An organized process of gathering evidence about the natural world. Science. Science is the systematic study of the structure and behavior of the physical and natural world through observation and experiment.

Species

A group of similar organisms that can breed and produce fertile offspring. Species. In science, a species is a category of living organisms that can mate and produce healthy, fertile children.

Stimulus

Anything that causes an organism to react. Stimulus. In science, a stimulus is something that triggers a response from a living thing.

Theory

Explanation of observations supported by evidence. Theory. In Science, a theory is a well-substantiated explanation of aspects of the natural world based on evidence and repeated testing.
