What is the purpose of testing one variable at a time in an experiment?

Back

To know what is causing the changes. This helps us understand cause and effect.

What is meant by 'keeping a variable constant' in an experiment?

Back

It refers to maintaining certain conditions the same throughout the experiment to ensure that the results are valid.

Why is it important to have a control in an experiment?

Back

A control allows for comparison and helps to isolate the effect of the independent variable.

Front

What is the scientific method?

Back

A systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is an independent variable?

Back

The variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

The variable that is measured in an experiment; it is affected by changes in the independent variable.

What is the significance of the Wright brothers' experiments?

Back

Their experiments laid the foundation for modern aerodynamics and contributed to advancements in space exploration.

Front

What is a controlled experiment?

Back

An experiment where only one variable is changed at a time to isolate the effects of that variable.
