Thermal Energy & Experimental Design

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, which determines its temperature and heat.

What is an independent variable in an experiment?

Back

An independent variable is the factor that is changed or manipulated in an experiment to observe its effect on the dependent variable.

Front

What is a dependent variable in an experiment?

Back

A dependent variable is the factor that is measured or observed in an experiment, which changes in response to the independent variable.

Front

What are constants in an experiment?

Back

Constants are the factors that are kept the same throughout an experiment to ensure that the results are valid.

Front

What is a control group?

Back

A control group is the part of an experiment that does not receive the independent variable and is used for comparison.

Front

What is an experimental group?

Back

An experimental group is the part of an experiment that receives the independent variable.

Front

How does increasing the height from which a ball is dropped affect its bounce?

Back

Generally, the higher the drop height, the higher the ball will bounce due to increased gravitational potential energy.

Front

What is the purpose of conducting an experiment?

Back

The purpose of conducting an experiment is to test a hypothesis and determine the relationship between variables.

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.

Front

What is a hypothesis?

Back

A hypothesis is a testable prediction about the relationship between two or more variables.
