Research involves investigating topics by collecting information from multiple sources and organizing it meaningfully. People conduct research to learn, for fun, to share information, or to become experts in their fields. Researchers include scientists, lawyers, doctors, teachers, actors, and students. A topic is the main idea being researched, while a subtopic is a smaller part of the main topic. When choosing a research topic, one should pick a topic they are interested in learning more about and find information for easily. Information can be found through books, interviews, videos, magazines, newspapers, and credible websites. Taking notes involves focusing on what is relevant to the topic and will interest readers, while avoiding plagiarism by paraphrasing information.
