Sports fans are familiar with slow-motion instant replays. Fans of nature shows have seen a flower bloom in a matter of seconds. But how, exactly, do people create videos that slow time down or speed it up?
In this lesson, students use unit rates to explore the frame rate of a camera and video player. They discover that filming at a high frame can be used to create a slow motion effect, while filming at a low frame rate can make motion look sped up. In the end, students have a clear idea of how these tricks work, and will be able to create stunning videos on their own!
