Doing research You should find out what other scientists have already discovered about your topic before you do your investigation. A good place to start is your school library. Here are some tips for searching the internet along with links to some of the more popular search engines. Using Search Engines Make a list of keywords before you start. Remember, they don't have to be single words.
Most search engines have a link for help in searching.
When your search results come back, read the description next to each link. Try to sort out those that are just trying to sell you something, and those that have real information. Sometimes the results descriptions give you new ideas for keywords and terms. Write them down for your next search.
