Science education in England
For the ages of 16, 17 and 18 (and older for those that remain in education below university-level), students in England do what is sometimes loosely called ‘key stage 5’ or KS5; it has no legal meaning (unlike the other key stages). And unlike KS1–4 in which the levels of complexity of topics learnt at each stage are prescribed within relatively narrow limits, at KS5, the levels of complexity of topics cover a wide range, although the highest level of complexity at KS5 is RQF level 3. Whether or not a student actually studies at this level of complexity in KS5 depends on his/her GCSE results—crucially on what subjects the student obtained passes at RQF level 2 standard (including mathematics and English) as well as the actual grades themselves. In other words, unlike KS1–4, where a specific student studies at one RQF level, at KS5, a specific student may be studying at several RQF levels depending on what s/he obtained at GCSEs. Regardless of the RQF-level mix, a KS5 student can do his/her post-16 study in one of the following:
Canadian Light Source
The Canadian Light Source (CLS) () is Canada's national synchrotron light source facility, located on the grounds of the University of Saskatchewan in Saskatoon, Saskatchewan, Canada. The CLS has a third-generation 2.9 GeV storage ring, and the building occupies a footprint the size of a football field. 
It opened in 2004 after a 30-year campaign by the Canadian scientific community to establish a synchrotron radiation facility in Canada. It has expanded both its complement of beamlines and its building in two phases since opening, and its official visitors have included Queen Elizabeth II and Prince Philip. As a national synchrotron facility with over 1000 individual users, it hosts scientists from all regions of Canada and around 20 other countries. Research at the CLS has ranged from viruses to superconductors to dinosaurs, and it has also been noted for its industrial science 
and its high school education programs.
