Who made major contributions during the Scientific Revolution?
Isaac Newton’s laws of motion and gravitation revolutionized science. His work unified celestial and terrestrial physics. Unlike philosophers or artists, Newton’s work reshaped modern scientific thinking.

The application of scientific knowledge for practical use is called
Technology applies scientific discoveries to create tools, devices, and systems. It bridges the gap between theory and practice. While engineering uses technology, the broader concept is technology itself.
Scientific laws summarize consistent natural patterns, often expressed mathematically. Unlike theories, laws do not explain why phenomena occur but state what happens. They are based on repeated observations.

In an experiment, the factor deliberately changed by the scientist is the
The independent variable is manipulated to test its effect on the dependent variable. Controlled variables remain unchanged to ensure fairness. This distinction helps identify cause-and-effect relationships.
Data includes recorded observations, measurements, or facts gathered through experiments. It forms the foundation for analysis and conclusions. Unlike opinions or guesses, data is evidence-based.
A controlled experiment isolates a single independent variable to determine its effect. All other factors are kept constant. This ensures reliable results and reduces confusion caused by multiple influences.

A testable prediction made before conducting an experiment is called a
A hypothesis is a tentative statement predicting what might happen in an experiment. It is testable and forms the basis for investigation. If supported by evidence, it can lead to theories or laws.

Which of the following is NOT part of the scientific method?
The scientific method values accuracy and evidence, so results must always be considered. Ignoring outcomes undermines reliability. Observing, hypothesizing, and experimenting are essential steps in the process.
3559
A well-tested explanation for a wide range of observations is called a
In science, a theory is a comprehensive explanation supported by significant evidence. It explains patterns and predicts outcomes. Unlike a hypothesis, which is a testable guess, a theory has been repeatedly validated.

The process of asking questions and testing ideas is known as
The scientific method is a structured approach involving observation, hypothesis, experimentation, and conclusion. It ensures reliability and reduces bias in results. Unlike guesswork, it relies on evidence and logical reasoning.
