Know your audience.
Science videos are useful for audiences of all age groups, from young kids to college graduates. When you set out to make a science video, you need to decide who it’s for and how much basic knowledge that audience will have. A third-grader will have much less context than a high school student or fellow science instructor.
Regardless of your audience, use simple, direct language as much as possible. Avoid technical jargon if you can, and if you do have to use technical terms, define them in a way your audience will understand.
Use and cite the right sources.
Accuracy and credibility are very important for science media. When doing research, use trusted sources like publications from academic institutions and primary sources as much as possible. Avoid using sources that are branded, commercial, or agenda-driven. “Really double- and triple-check the resources you’re using,” says science educator Jessica Purcell. “Make sure they’re credible and unbiased.”
Cite your sources. Established science YouTube channels like CrashCourse and Veritasium will have a small bit of text pop up whenever the speaker makes a factual claim, with a link to the source. Link to all of your sources in the YouTube video description and on whatever other pages you use to promote the video. This not only bolsters your own credibility and trustworthiness, but it also provides more resources to viewers who want to learn more about the topic and go deeper.
