Observation
In science, an observation is the active and systematic process of gathering information and data using one’s senses or scientific instruments to understand a phenomenon or object in the environment.
Hypothesis
In science, a hypothesis is a testable and falsifiable proposed explanation for a phenomenon or a prediction of a relationship between variables, derived from prior knowledge and observations.
Experiment
In science, a hypothesis is a testable and falsifiable proposed explanation for a phenomenon or a prediction of a relationship between variables, derived from prior knowledge and observations.
Data
Data science is an interdisciplinary field that uses scientific methods, processes, algorithms, and programming to extract knowledge and insights from data, blending principles of mathematics, statistics, computer science, and domain expertise.
Conclusion
In science, a conclusion is the summary of an experiment’s results, interpreting whether the data supports or refutes the original hypothesis.
Theory
In science, a theory is a comprehensive, evidence-based explanation for observed phenomena that has been repeatedly confirmed through observation and experimentation.
Law
A scientific law is a statement that describes an observable natural phenomenon that has been repeatedly verified and appears to be consistently true under specific conditions.
Independent Variable
In science, an independent variable is the factor that a scientist changes or manipulates in an experiment to observe its effect on another variable.
Dependent Variable
In science, an independent variable is the factor that a scientist changes or manipulates in an experiment to observe its effect on another variable.
Controlled Variable
In a science experiment, a controlled variable (or constant variable) is any factor, other than the independent variable, that is intentionally held constant to ensure that it does not affect the outcome or dependent variable.
Control Group
In science, a control group is the group in an experiment that does not receive the experimental treatment, serving as a baseline or comparison to the experimental group (which receives the treatment).
Experimental Group
An experimental group is the subset of subjects in a research study that receives the experimental treatment or intervention being tested, as opposed to the control group.
Trial
“Trial science” is not a single, unified concept but refers to two distinct fields: clinical trials, which are scientific studies testing new medical interventions in humans, and trial science in law, which applies psychological and research principles to legal proceedings to understand jury behavior and improve trial strategies.
Bias
In science, bias is a systematic error that can distort the results of a study and lead to inaccurate conclusions.
Placebo
The placebo effect is a phenomenon where a person experiences a beneficial health outcome after receiving an inactive treatment, such as a sugar pill or sham procedure.
Meter (M)
It is defined as the distance light travels in a vacuum in 1/299,792,458 of a second.
Gram (G)
It is defined as one-thousandth of a kilogram.
Kilogram (kg)
In science, a kilogram (kg) is the International System of Units (SI) base unit of mass, defined by a fixed numerical value of the Planck constant (h) as 6.62607015 x 10⁻³⁴ J·s.
Kilometer (km)
In science, a kilometer (km) is a metric unit of length, a multiple of the base unit of length, the meter, and is defined as exactly 1,000 meters.
Milliliter (mL)
Metric unit of length equal to one thousandth of a meter. synonyms: millimetre, mm. metric linear.
Centimeter (cm)
Centimeters are metric units of measurement that are useful for measuring lengths of small objects, just like the imperial unit of inches. Centimeters are smaller than inches; it takes 2.54 centimeters to equal 1 inch. There are 100 centimeters in 1 meter, and there are 10 millimeters in each centimeter.
Millemeter (mL)
Definitions of millimeter. a metric unit of length equal to one thousandth of a meter. synonyms: millimetre, mm. metric linear unit.
Celcius (C)
In science, Celsius (°C) is a temperature scale where water freezes at 0° and boils at 100° at standard atmospheric pressure, with 100 equal intervals (degrees) between these points.
