The basic components of a scientific experiment are the types of variables included in the experiment which are dependent (to be studied), independent (can be changed)  and the constant variables (remain same).

The experiment is also influenced by another variable called confounding variable which directly influence these basic variables and can cause or produce the useless results in an experiment.

The basic components (depedent and indepedent variables) are the plants and altitude while the confounding variable is the 20 story building. Confounding variables affect the experiement variable and are mainly outside of the researcher’s control in the experiment.  Ray cannot change the building but this variable can affect the depedent and indepedent variables and cause distorted or spurious results.
