Here at science made simple we are keen to inspire not only the next generation of scientists but also the next generation of science communicators. Supporting work experience students each year is an important part of what we do.  Our work experience students get a chance to see a range of the activities that science made simple is involved with and we always set them challenge to produce some science communication themselves, whether designing a demo, delivering a short presentation or, in this case, writing a blogpost that includes all of these!
