Part B: Find Credible Sources
When designing a science presentation, look for credible sources. Science doesn't show bias, but humans
do. Avoid sites and articles that provide facts without citing proper scientific evidence. You must be able to
identify reliable sites so that the data in your presentation is credible.
Use sources that end in .gov, such as CDC.gov. These government sites are reliable sources. You can also
use sites ending in .edu. They are usually trustworthy, but sometimes students, not scientists, write
content for .edu websites. Always identify the source's author before proceeding. Some.org and.com
sites are credible, but it's important to verify their authenticity. When reviewing a source, ask these
questions:
.
.
.
Who is the author?
Is this person an HIV or AIDS expert?
What is the document's purpose?
Does the document state facts that scientists can prove with evidence?
• Are there opinions in the document?
• How old is the document?
Do other credible sources support the statements in the document?
.
Search for credible websites and note the information they contain. Write down two sources that you will
use for your presentation, and cite them using Modern Language Association (MLA) citation methods.
