Videos On Scientific Subjects: Cheetah Hunts Gazelle, Worlds Deadliest

Go to the internet, or YouTube, or both. Find two science websites or videos on scientific subjects, one that you think is really good, and one that you think is bogus. If you can find sites related to chemistry, great, but other sciences are fine.
For the “bogus” site, I’ll be most impressed if you find something that looks credible, but is actually not true.
Note the web addresses or identifying information from YouTube here:
Good site:
Bogus site:
Now comes the most important part of the exercise. Explain how you decide whether something you read or see on the web is true or false. How did you decide that your bogus site was not telling the truth? Do you apply the same criteria to something you see on TV or read in the paper? Please be thoughtful in your answer, and write it.
The aim of this exercise is to make you think about the criteria for good, believable sources, and criteria for sources that are trying to fool you.
