Scientific Method and Scientific Investigation

A set of practice flashcards covering key concepts of the scientific method as described in the notes.

What is scientific investigation?

A plan for asking questions and testing possible answers by following the scientific method.

What typically starts a scientific investigation?

Observations—things detected with the senses (sight, hearing, touch, smell, taste).

What is a hypothesis?

A possible, logical, testable answer to a scientific question that is based on knowledge and is falsifiable.

What is a prediction?

A statement of what will happen under certain conditions, often expressed as if/then.

What is evidence in the scientific method?

Data that can support or disprove a prediction and test a hypothesis.

What does it mean to test a hypothesis?

To gather evidence and determine whether the prediction is supported or refuted.

Can a hypothesis be proven true?

No; evidence may support it, but it cannot be conclusively proven true.

What is drawing conclusions in the scientific method?

Interpreting the collected evidence to decide whether the hypothesis is supported and how strong the support is.

What is communicating results?

Sharing methods, data, and conclusions with others so they can test and verify findings, and identify possible errors.

What is the difference between a hypothesis and a prediction?

A hypothesis is a testable answer to a question; a prediction states what will happen if the hypothesis is true.

Why must a hypothesis be falsifiable?

To allow observations that could disprove it if it is false.
