Compare and Contrast
In order to find contrasts, or what is different between two things, it can be helpful to compare, or figure out what is the same between them as well. Comparing and contrasting puts two or more subjects side by side in order to draw insights from their similarities and differences.
A Venn Diagram can help you organize the information you will use. A Venn Diagram shows visually what two or more subjects have in common and what characteristic they have that they do not share. What you choose to contrast depends on your topic.
Compare and contrast a car and a bicycle in a Venn Diagram.
