In an experiment on plant growth, what is the independent variable if different liquids are used?

Front

What is a dependent variable?

Back

The part of the experiment that is measured or observed, which changes in response to the independent variable.

Front

In an experiment where a ball is dropped from different heights, what is the dependent variable?

Back

Front

What is a controlled variable?

Back

Factors that are kept constant throughout the experiment to ensure a fair test.

Front

In the plant growth experiment, what are some examples of controlled variables?

Back

The amount of soil, sunlight, and type of plant.

Front

What is the purpose of an experiment?

Back

To test a hypothesis by manipulating variables and observing the effects.

Front

How does changing the independent variable affect the dependent variable?

Back

The dependent variable changes in response to the manipulation of the independent variable.

Front

What is a hypothesis?

Back

A testable prediction about the relationship between the independent and dependent variables.

Front

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

Back

To provide a baseline for comparison and to ensure that the results are due to the independent variable.
