About this Masterclass
Parabolas are beautiful mathematical shapes occurring in many every-day, scientific and natural contexts.
Through the demonstrations and activities in this session, students explore parabolas and their intriguing characteristics. They will learn about uses of parabolas in science and architecture as well as exploring natural parabolas such as the path a ball follows when thrown through the air. The students go on to create some of their own parabolas using a range of pleasing techniques such as paper folding and curve stitching.
Length: 2 hours (see the session leader notes for ideas on how to shorten the Masterclass).
