What is the dependent variable in an experiment?

Back

The dependent variable is the variable that responds to the change and is measured or observed in an experiment.

Front

What is a procedure in scientific investigation?

Back

A procedure is a step-by-step list of how to carry out an investigation.

Front

In which direction does thermal energy transfer?

Back

Thermal energy transfers from a warmer object to a cooler object.

Front

What is the definition of a dependent variable?

Back

A dependent variable is the variable that is affected by changes in the independent variable.

Front

What is the definition of an independent variable?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total energy of all the particles in an object.

Front

What is an example of thermal energy transfer?

Back

An example of thermal energy transfer is when a hot cup of coffee warms your hands.

Front

What is the purpose of a hypothesis in an experiment?

Back

A hypothesis is a proposed explanation for a phenomenon, which can be tested through experimentation.

Front

What is the role of controlled variables in an experiment?

Back

Controlled variables are the factors that are kept constant to ensure that the experiment tests only the effect of the independent variable.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
