How Corona Virus Affects Your Body? is a YouTube video produced by Peekaboo Kids in May 2021.  It is published on YouTube and mainly introduces the pandemic, how COVID-19 spreads, and how it affects human bodies to kids with less prior knowledge of biology and medical issues. As the contents of COVID-19 contain very complex information and are hard to understand for children, this video aims to use cartoonish animation and sound effects to motivate children and explain difficult concepts in a more simplistic, understandable, and entertaining way. 

In the video, the cartoon character Dr. Binocs (Figure C2) takes the role of an expert and a narrator to explain concepts to kids with conversational language. The instructional designer applies the Voice Principle in the video as they present Dr.Binocs with a natural human voice that allows the children to feel more engaged and more conversational with the learning content. 

However, although this video has a good implication for the Voice Principle, it ignores some functional principles, such as [https://ectwiki.online/index.php?title=Segmenting_Principle segmenting principle] and [https://ectwiki.online/index.php?title=Signaling_principle signaling principle] that failed to keep children focus on the video for a long time and distracted by other unnecessary content which increased kid's extraneous load as a result.
