“It’s a programme of UK-wide events that get students excited about science, technology, engineering and maths.”
They may include theatre shows, exhibitions, some hands on and other interactive events. Along with careers info in STEM areas.
It is led by Engineering UK, so they may a engineering theme to them. Not sure: I’ve not been to one yet.

Some 300 events all held in Cambridge in March. Some are drop-in; some need to be pre-booked, and they can book up fast.
Really aimed at teenagers, looking to find out more about science, though kind of interesting to anyone interested in science. It is run by the university and so the science and the researchers are world class.
The day I went to was very busy, though well worth the effort.
