Identify the variables from the experiment below.
Timmy has decided he wants to test which if music can read help flowers grow. He decides to expose some roses to classic music 10 minutes every day. He will have another group of roses that will receive no music and a third group that will get music for 20 minutes per day. Timmy makes sure to have the same types of plants in each group and to expose them to music at the same time during the day. He also makes sure that all plants get the same amount of water and sunlight each day. At the end of 2 weeks, Timmy measures the height of all plants to see if the music made a difference.
identify the independent variable, dependent variable and at least 2 control variables in this experiment.

An <B>independent variable</B> is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.
A <B>dependent variable</B> is the response or measure of results.
<B>Extraneous variables</B> â other than the independent variable â potentially can affect the dependent variable, so they must be controlled. If possible, you try to keep them constant between the experimental and control group.
The <B>experimental group</B> receives the independent variable.
The <B>control group</B> is similar to experimental, except it does not receive the independent variable. Extraneous variables are balanced between experimental and control groups.
