When making a science presentation, look for credible sources. Some websites present information as evidence that has not been scientifically proven. You must be able to identify reliable sites so the data in your presentation is credible. Sources that end in .edu (school and college websites) and .gov (government websites) are great resources to use. However, sometimes students, not scientists, write content for .edu websites. Because the content might not be checked by scientists, read any .edu website carefully to find out whether it is reliable. Some .org and .com sites are also credible, but you have to read the content carefully to determine how legitimate it is. When you review a source, ask yourself these questions:

Who authored the article?
Is the author a scientific expert in climate change?
What is the purpose of the article?
Does the article state facts that can be proven by evidence, or is it made up of opinions?
When was the article written?
Do other credible sources support the statements in this article?
Which scientific studies support the information in the article?
Now find two to three credible websites that you can use to find information for your presentation. Write them down. They can be e-books, magazines, websites, and so on. Also, write down one to two sentences for each source explaining how the source will help you. You will find some websites in the Resource section of this activity. Show how you will cite the sources in a works cited page at the end of your presentation using MLA (Modern Language Association) citation methods.
