Can scientific laws change?

Back

Scientific laws do not change, but our understanding of them can evolve with new evidence.

What is the difference between repetition and replication in scientific experiments?

Back

Repetition is when a scientist repeats the same experiment multiple times; replication is when other scientists conduct the same experiment to verify results.

Front

Why is replication important in science?

Back

Replication is important because it helps to confirm the validity of experimental results and ensures that findings are reliable.

Front

What does it mean when a theory is described as 'well-supported'?

Back

A well-supported theory is one that has been extensively tested and confirmed by multiple lines of evidence.

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 masses.
