Use Google to generate keywords and predict the scope of your topic.
Google for Topic Development
In Google, the keywords you type in, or pages consisting of your keywords, will be shown as the first hits in your results list.
Google is capable of sorting results in a ranked manner, according to how close the words are to each other. When you type in a phrase place quotation marks at either end: "life on Mars" to make your search even more specific: this tells Google to locate the words next to each other.
Early in your search, look at the source pages or documents returned by your first search for new words that better describe what your topic, or describe your topic differently.
Google Tip

Rather, you are looking for information that will
DETERMINE THE ANSWERS YOU NEED.
