Here are a few more Google search tips:
To find specific types of websites such as .gov or .edu type in the search box Site:.gov or Site:.edu.
To eliminate specific websites or words you can use a minus symbol before the word. For example if you want to search for something but do not want Wikipedia to show up in the results simply type in the search box -Wikipedia.
Use quotations around a phrase to search for results containing that exact phrase. For example search for "climate change" will return less, but more relevant results than searching for the phrase without quotation marks.
