The Primary Science Education Conference (PSEC) run by the Primary Science Teaching Trust (PSTT) offers an inspirational and hugely worthwhile experience to hundreds of primary science practitioners.  This special issue of 'Primary Science' allows those of you who couldn't make it, and those who missed a session to attend an alternative one, the chance to read about the work that teachers have been doing - a range of topics and ideas, all easily accessible and do-able in the classroom.
