How does a scientific theory differ from a scientific law?

A theory is an explanation of things or events

A theory is a description of what happens in nature

A law explains why events occur

A law is based on a single observation

What is one limitation of science according to the text?

Science cannot explain or solve everything.

Science can answer all questions about values.

What must a scientist do to ensure their guesses are valid?

Make sure guesses can be tested and verified.

Assume guesses are always correct.

What is a scientific law?

A statement that seems to be true all the time.

An explanation based on observations.

A theory that cannot become a law.

What is the definition of "measurement"?

The dimensions, capacity, or amount of something

The amount of matter in an object

The physical property of matter

The amount of space occupied by an object

How is density defined?

Physical property of matter that can be found by dividing the matter’s mass by its volume

The amount of space occupied by an object

The amount of matter in an object

An exact quantity people agree to use to compare measurements

Why are measurement standards necessary?

To ensure consistent and comparable measurements

To ensure everyone uses different methods

To allow for personal interpretation

To make measurements more complex

Which of the following is an example of something measured in millimeters?

The distance between two cities

What is one advantage of converting to the International System of units?

It is based on multiples of ten.

It is harder to compare measurements.

Why is it important to have exact standards of measurement?

They provide a consistent, known, and accepted value for a base unit.

They are flexible and can be adjusted as needed.

They are only used in scientific experiments.

They vary from country to country.

Organize the following measurements from smallest to largest: kilometer, nanometer, centimeter, meter, and micrometer.

Nanometer, micrometer, centimeter, meter, kilometer

Kilometer, meter, centimeter, micrometer, nanometer

Micrometer, nanometer, centimeter, meter, kilometer

Centimeter, nanometer, micrometer, meter, kilometer

Why is density considered a derived unit?

It is made up of two SI base units, mass and length.

What is the definition of "data"?

Information gathered during an investigation or observation

A visual display of information or data

A type of graph with vertical bars

A visual display of information or data

A type of scientific experiment
