An essay is a short piece of writing on a specific topic. Common topics which might be assigned in a public school setting include "Should Homework Be Abolished?" "Why Should You Brush Your Teeth," "What Is Your Favorite Place To Go On Vacation," "What Can We Do To Save Water/Energy," etc. Usually essays are one to three pages in length. Students simply make a thesis statement (usually state an opinion) and then defend that opinion by providing evidence or coherent reasons why the opinion is valid.
