Science videos work best when you’re clearly describing a specific topic or experiment. Because so many topics are enormous, it can be tempting to go off into digressions or delve into details during a video. However, if you’re making learning material for high school students or a younger audience, you have to hold their attention and make sure they understand. Stay focused.
If you’re doing a video that explains a science experiment, break it down into well-defined steps. Outline ways that students or other learners can do it themselves and achieve the same results. Replicating results is part of the scientific method, and if your viewers can replicate what you do onscreen, they’ll have a greater appreciation and understanding for what you’ve taught them.
If you’ve made videos about related topics, link to them. A video about the circulatory system could include links to the respiratory and digestive systems, and a video about ecology could link to another video about climate change. Group videos together into a YouTube playlist or your YouTube channel, and make sure your new work calls back and links to your old work.
