STEM Career Role Models are practising scientists and engineers who are happy to offer their specialist knowledge and expertise to schools. Keen to excite students about science, technology, engineering and maths, they hope a visit to a school will allow students to see where the STEM subjects could take them in the future. Planetary scientist Sheila Kanani visits The Hollyfield School in Surbiton to deliver a workshop on comets. Using a variety of common household ingredients and some dry ice, she demonstrates how it's possible to cook up a comet in the classroom. She also explains to students how they can follow in her foot steps and pursue a career in space science. The programme also features a profile of Sheila in which she tells us about her work on the Cassini spacecraft, currently orbiting Saturn, and gives us an insight into what it's like to work on cutting edge science.
