Front

What is density?

Back

Density is the mass of a substance divided by its volume, typically expressed in grams per cubic centimeter (g/cm³).

Front

What is the formula for calculating density?

Back

Density = Mass / Volume

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is a controlled variable?

Back

A controlled variable is a factor that is kept constant throughout an experiment to ensure that the results are valid.

Front

What units do we use to measure mass?

Back

Grams (g) are used to measure mass.

Front

What units do we use to measure volume?

Back

Milliliters (mL) and cubic centimeters (cm³) are used to measure volume.

Front

What is an observation?

Back

An observation is a statement based on what one sees, hears, or experiences.

Front

What is an inference?

Back

An inference is a conclusion drawn from observations, often based on reasoning.

Front

How do you determine the cause and effect relationship in an experiment?

Back

By identifying which variable is manipulated (independent) and which is measured (dependent).
