What do you need to create a graph?

Back

Data is required to create a graph.

Front

What units are used to measure density?

Back

Density is measured in grams per cubic centimeter (g/cm³).

Front

On which axis is the independent variable represented in a graph?

Back

The independent variable is represented on the X-axis.

Front

How do you order liquids from most dense to least dense?

Back

To order liquids from most dense to least dense, you compare their densities.

Front

Which state of matter allows particles to slip and slide past each other?

Back

In the liquid state, particles can slip and slide past each other.

Front

What is the definition of density?

Back

Density is the mass of an object divided by its volume.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is an independent variable in an experiment?

Back

An independent variable is the variable that is changed or controlled in a scientific experiment.

Front

What is a dependent variable in an experiment?

Back

A dependent variable is the variable that is measured and affected in an experiment.

Front

What is the purpose of a control group in an experiment?

Back

A control group is used as a standard for comparison to determine the effect of the independent variable.
