What is a scientific theory?

Back

A scientific theory is a well-substantiated explanation of an aspect of the natural world that is based on a body of evidence and can be tested through experimentation.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., mass, height).

Front

What is a control group in an experiment?

Front

What is a scientific law?

Back

A scientific law is a statement that describes an observable phenomenon or a relationship in nature that is consistently true under specific conditions.

Front

How are scientific laws and theories related?

Back

Both scientific laws and theories are developed based on extensive observations and experiments, but laws describe what happens, while theories explain why it happens.

Front

What is an example of a scientific law?

Back

An example of a scientific law is Newton's Law of Universal Gravitation, which describes the gravitational attraction between two masses.

Front

What is an example of a hypothesis?

Back

An example of a hypothesis is: 'If plants are given more sunlight, then they will grow taller than plants that receive less sunlight.'

Front

What is the purpose of a scientific experiment?

Back

The purpose of a scientific experiment is to test a hypothesis by manipulating variables and observing the effects.
