What is the dependent variable in tornado in a bottle?

Answer;

The amount of water and the temperature of the water and the angle the bottle was set in.

Explanation;

The two main variables in an experiment are the independent and dependent variable;

-An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.

For example; the dependent variable in tornado in a bottle is the amount of water and the temperature of the water and the angle the bottle was set in.
