Today through March 19th (or 19 March, since the British like to do things wrong even if they make more sense) is British Science Week, where they celebrate Science, Technology, Engineering and Math (STEM) in a formal way. Informally they celebrate it every day, since they use cell phones, televisions, mass transit and residents of London are photographed by government 300 times each day.
They have citizen science programs, activity packs for all ages
and even a 5K run. I don't know how running a 5K fits into science but neither does dancing your PhD, and that's still pretty cool.
