Laws vs. Theories

In science, a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.

• Fact
• Theory
• Law
• Hypothesis

Laws tells us that it happens but doesn’t describe how or why.

• True
• False

Scientific theories are based on

• general assumptions of how systems work.
• mathematical principles that can be proven true.
• large amounts of data collected over time.
• observations from within only one scientific discipline.

Can you disprove a scientific theory based on a single experiment?

• Yes

• No

Theories are based on thousands of supported hypothesis and tons of physical evidence.

• True

• False

This is often expressed in a mathematical equation like E=MC² or F = M x A

• Scientific Law

• Scientific Theory

• Hypothesis

• All of these

A scientific theory can become a law if it has enough evidence to support it.

• True

• False

A scientific law is a repeatable pattern in nature

• True

• False

A scientific law can be demoted to a theory if information is produced questions it's validity.

• True

• False

Check all the statements that apply to a scientific theory.

• States that an event will occur

• A repeatable pattern in nature

• Can be rejected or modified

• Based on repeated observations

• Explains how or why an event occurred
