Multiple Choice

Which of the following statements about scientific theories and laws is correct?

• A scientific law can be disproven easily.

• A theory is an explanation supported by evidence.

• Theories are always mathematical equations.

Open Ended

Classify each statement as a hypothesis, theory, or law: 1) We all descended from a common ancestor. 2) Life on Earth began due to aliens. 3) Since ink is transferred to paper, it can be transferred to anything.

Multiple Choice

Multiple Choice

What is the difference between a conclusion and an inference when analyzing data?

• A conclusion is based on what you actually see, while an inference involves further reasoning from evidence.

• A conclusion is always true, while an inference is always false.

• An inference is based on what you actually see, while a conclusion involves further reasoning.

• Both conclusion and inference mean the same thing.
