I don’t know much about insects. If I were assigned an essay in my biology class about the life of ants, I would have a major case of writer’s block. It would be necessary for me to learn about them and their everyday activities in order for me to even know what to begin writing. So, if your problem is unfamiliarity of the assigned topic, visit Google (or your preferred
search engine) and spend a few minutes learning about it. Take notes while you’re reading, and then use those notes as an outline for your essay. You can then decide what is worth mentioning and what parts of your research are irrelevant to the paper.
