I am teaching Calculus (one and also several variables). I would like to create questions in which students would watch a short video and then answer a question related to the content of the video. In this way, students might find it interesting and appreciate the subject. The video is not necessarily related to Maths (directly), but at some point in the video we could ask a simple question related to Calculus, such as limits or derivatives.
I would think that there are only a very few such videos on the internet. Nevertheless, could you recommend me a video?
