One thing I noticed when I ChemEd-Ireland returns to UL visited several schools starting the new courses On Saturday October 21 st ChemEd-Ireland returns was that the Nature of Science (NoS) was being to the University of Limerick. The theme of this taught as a stand-alone topic. This is not the year’s conference is ‘Chemistry and Society’ and intention of the syllabus as NoS is supposed to be the organising team is led by Dr Sarah Hayes of integrated across all the themes as appropriate. In SSPC. Registration will be available through many of the new textbooks NoS is dealt with at Eventbrite. ChemEd-Ireland started on the UL the start as a separate topic and this may be the campus in 1982 and ran for 25 years there before cause of the way it is being taught.

This year’s bill service courses for the new course before it was of fare includes climate change and the chemistry introduced, due to the ASTI boycott of the new of food. We hope to publish the Proceedings in Junior curriculum. This is certainly an issue to be the Spring issue (#111). The conference went off addressed by the Junior Science support team as well despite Storm Brian and over 70 people teaching NoS as a topic may undermine its use in attended. the course. It remains to be seen whether the new shorter course (200 versus 240 hours) is a good Philip Ryan, RIP preparation for the senior cycle science courses. I was very sad to hear of the recent death of James Philip Ryan, the long-serving secretary of the Major science education conference Institute of Chemistry of Ireland. For many people in Dublin in the last 30 years he was the Institute and his From August 21-25 Dublin City University hosted hard work and cheerful manner will be greatly the European Science Education Research missed.

This page highlights some of 11.8 km of sticks to join them. the items, as started in the last issue, to encourage The summer is always a busy time for conferences you to browse. and workshops and in this issue we have a number We have several practical articles: by Enda Carr on of reports (pp. 46-59), ranging geographically from using Ziploc bags to do safe chemistry (p. 34); and Belgrade, Serbia to Debrecen, Hungary; from two TEMI ideas, one on density using the Limerick to Cork to Dublin. One reason for putting polydensity bottle(p.30) and one on the in the reports is to whet your appetite for next year disappearing precipitate (p. 32); also an article on – maybe you would think of going to Cork for the the chemistry of the brown ring test for nitrates (p. BASF Chemistry Workshop or to Limerick next 28). (If you have anything like this that you want summer for the Chemistry Demonstration explaining, please contact peter,[email protected].) Workshop. Miriam Hamilton contributes an interesting Opinion Practical work is important in science, something article on the integration of the three main sciences established in schools in England and Ireland since in the junior science course (p. 23). Do you have the 19 th century. In many countries practical work strong opinions on something connected to teaching does not have such a central place and science is chemistry or science in school? Why not send in an often taught from the book. The Gatsby Foundation article for the Opinion feature? in the UK has funded a recent report on Practical Work in schools, written by Professor Sir John Emma Ryan, an ex-student of UL, describes her Holman, which lays down benchmarks for school experience of teaching science in New York, after practical work. There is much that we could learn several years teaching in Ireland (p. 19). from this report and summary is given on p. 7.
