A sample compare and contrast essay can be the ideal start to write about two texts, two scientific experiments, two separate events you may have experienced, or two case studies to work with. You may have to compare and contrast to establish a relationship between two similar elements that have some essential differences. For example, you could have two fungicides that have very different effects on plant life.

Let us look take a sample compare and contrast essay. You may have two teachers who have very different views on political events going to unfold in the country, but it could be that they have the same perspective of how a school or college project should be written. There are methods you could use to establish the difference. One such method is the keyhole comparison where you give less weight to any one element than the other. You do this by using the first element as a lens or keyhole to view the other. For example, if you look through at an object from afar using binoculars, you would view it differently than without the binoculars.
