Work experience
The aim of work experience is to provide an experience of work, rather than just to try a particular job, though that can be included. The idea is that young people should have the opportunity to develop their transferable skills and, if possible, to put some of their science and maths skills into practice, or observe others using theirs.
If you are looking for opportunities related to science or maths you can get ideas from friends, family, online business directories or business directories in your local library.
