In a nutshell, citing information means giving credit to the creator of information that you use in a project. It is the right thing to do! Plaigarism occurs when you do not cite your sources correctly or do not get proper permission to use copyrighted works.
When to Cite
CIte your source if:
-you use a direct quotation
-you paraphrase information in your own words
You do not need to cite your source if:
-the information you include is common knowledge (like the capitol of a country)
Tools for Writing Citations
The Purdue University Online Writing Lab is an extensive resource for completing correct citations. The good news is that there are several sources that will build a citation for you, such as Easy Bib and Citation Maker. Many databses also create citations for you as well. You do need to make sure the citations these tools create match what your teacher expects before you turn in the assignment.
Fair Use/Getting Permission
Sometimes you need permission from the author/creator to use the work in your project, particularly if it is posted online. This website clearly explains what you can legally include in presentations.
