Part B When designing a scientific presentation, look for the most credible sources. Science doesn't show bias, but we humans
tend to show bias. There are sites and articles that provide facts without proper scientific evidence. Avoid using
information from such sites. You must be able to identify reliable sites so the data in your presentation is credible
Use sources that end in. gov (government sites), such as CDC. gov. They are reliable sources. You can also use sites ending
in .edu. They can be deemed trustworthy, but sometimes the information is written by students rather than scientists.
Always find out who the author of the article is before proceeding. Some. org and. com sites are credible, but you need to
analyze the contents to verify their authenticity. As you review a source, always try to answer these questions:
• Who authored the article?
Is this person a scientist or an expert in chemistry?
• What is the purpose of the article?
• Does the article state facts that scientists can prove with evidence?
• Are there opinions in the article?
• How old is the article?
Do other credible sources support the statements in this article?
Find some credible websites, and note the information they contain. Write down two or three sources that you'll use for
your presentation, and cite them using MLA (Modern Language Association) citation methods . Write one or two
sentences stating how the source will help you answer the questions from part A.
