The scientific study of life

Biology

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

The standard used for comparison of test results in an experiment

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.

Information gathered through observation

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.

The factor measured at the end of an experiment

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.

The change in a species over time

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.

Testing a hypothesis by collecting data in controlled conditions

Experiment

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

The maintenance of the stable internal conditions in an organism

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.

A possible explanation or answer to a scientific question

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.

The variable which is manipulated by the researcher

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.

A logical assumption based on prior experience

Inference

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

The sum of all chemical reactions in an organism

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.

The process of using your senses to gather information

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.

Any living thing

Organism

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

The process of making offspring

Reproduction

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

An organized process of gathering evidence about the natural world

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.

A group of similar organisms that can breed and produce fertile offspring

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.

Anything that causes an organism to react

Stimulus

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

Explanation of observations supported by evidence

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.
