to research you first have to think. What are your sources? You can research by the internet, books and even ask your parents. When researching ask your basic questions: who what where when why how.
For example:
If your doing research on the titanic. Think: who were on the titanic? What is the titanic? Where did the titanic sail? when did the titanic sink? why is this knowledge important? how did the titanic sink?
If your doing research on social studies think of a story. What happened from the titanic from beginning to end? Believed it or not, research is actually the easiest part. Afterward you must learn to apply your research.
