Chemistry
Leaving Certificate chemistry aims to provide a relevant course for students who will complete their study of chemistry at this level while, at the same time, providing a foundation course for those who will continue to study chemistry or a related subjects following completion of their Leaving Certificate. This syllabus is for students in the senior cycle of post-primary education and is assessed at Ordinary and Higher levels.
Adjustments to the Leaving Certificate Chemistry Syllabus (Changes in September 2013)
The Leaving Certificate chemistry syllabus has been adjusted as a result of a ban on substances that have been designated as Substances of Very High Concern by the European Chemicals Agency. The theoretical content of the syllabus is not being changed. Four of the mandatory experiments have been adjusted. Three are being adjusted to accommodate the removal of banned substances and one that did not require the use of a banned substance is being extended to ensure that the overall amount of practical work in the syllabus does not change.
Circular letter 0047/2013
Teaching guidelines for each of the adjusted practicals can be found here

CHEMISTRY STUDENTS ON TOUR IN NUI, Galway
Biology, Chemistry & Engineering Departments February 28th 2014
Biology, Chemistry & Engineering Departments February 28th 2014
The School of Chemistry welcomed 33 students from PCH to NUIG today. The students were treated to a two hour tour conducted by Seamus Collier. This included visits to many chemistry labs and a motivating talk on career choice given by Dr. Niall Geraghty. The Electron Microscope was viewed and described with great enthusiasm. NMR and Gas Chromatography were looked at in awe. With some costing close on half a million, its unlikely we will see them in PCH in the near future!!
We visited the Kingfisher gym and saw the many wonderful resources on offer to students. No tea break in sight two hours on, we crossed the campus to the Engineering building. Here we were met by Damien Dooley, a PCH graduate of whom we are immensely proud. He is currently working on a PhD which will result in a car which is hands-free in a very special way. It drives itself! Damien gave us a wonderful presentation which dealt with every aspect of Engineering from Biomedical to Mechanical to his own speciality, Electronic Engineering. He held the rapt attention of his audience as he lay the world at their feet regarding what they could aspire to. He was hugely motivating as well as being an expert in his field. Another enthusiastic engineer swept us off on a tour of various departments we 'just had to see'. We saw a little of the sports lab where students were 'wired up' to computers to track their movements. Just not enough time to do everything. We raced off to the canteen, starving and tired from information overload. It didn't take long for the sight of Starbucks to raise the spirits. What a day.
We are immensely grateful to all NUIG staff that made our day so enjoyable. See photos on your web page for good memories of a great trip. M.Healy :)
