Example: "The researchers conducted an experiment to demonstrate the effects of temperature on enzyme activity."
Alternatives: "a test to illustrate" or "a study to showcase".
Newton bluntly refused to correspond but, nevertheless, went on to mention an experiment to demonstrate the rotation of Earth: let a body be dropped from a tower; because the tangential velocity at the top of the tower is greater than that at the foot, the body should fall slightly to the east.
Prior to the analytical and numerical study, an experiment to demonstrate stochastic resonance in a mechanical system is described.
In the latter part of this paper, we describe an experiment to demonstrate the friction characteristics between a fingertip and the plastic plate we used in the experiment.
