Students Art Work

Below Are Examples of art work which were created in the De La Art Department. To see more recent work, the De La Salle art Teachers have set up a blog. The blog has students work from 2010 and it will be updated on a regular basis. The Blog will also have information on art colleges and useful website links.

It was an early start - dragged up at 6:00 a.m. to get the Matthew's bus to Whitehall. However, it wasn't to be. Ryan was just awakening from his slumber around 7:00 when we phoned him so we patiently waited and got the 7:30 bus. Even so, Ryan nearly managed to miss it again and had to run to catch the bus ! The moral of the story - a contingency plan is always worth the extra 5 minutes it takes to come up with it.

We found the RCSI Smurfit building quite quickly, navigating treacherous icy paths and dubiously signposted housing estates to reach it. The Santa Sabina girls proved to be a very strong and polished proposition. We had our speeches well rehearsed, however, with Conor providing a dash of humour and Fritz putting the factual icing on the cake. On the day, though, it just wasn't to be. Apparently words such as 'evil' and 'soul' constitute emotive language. Who knew!

Afterwards we played the gracious losers and wished the girls, who seemed like thoroughly decent people, well in the subsequent rounds of the competition... hoping to have the honour, at least of being beaten by the eventual national champions! Incidentally, Ryan collected a hug from each of the nine girls against us, but was denied one by Fiona (the organiser) - it would be slightly inappropriate, after all.
As a consolation prize, Fiona gave us an impromptu and fascinating tour of her laboratory. We got to see microlitre pipettes and cell cultures... it was all very exciting as you can imagine. Then, all cheered up by Fiona and her colleague "Izzy", we took the bus in to the city and made the small stroll to the ambassador to see the Bodies exhibition. While not exactly appealing, it was still a fascinating experience. Very educational all the same.

The display seemed to be intended to raise people's awareness of cancer and general health as there were a lot of blotchy, disgusting-looking cancerous tissues, including cancer of the... let's not go there.

Also on offer was an exhibit of embryos at various stages of development which managed to amaze and disturb simultaneously.
Afterwards we had a bite to eat in the luxury establishment that is Supermacs, then caught the 14:00 bus (on time) back for 3:30; too late for school, but not too late for applied maths - well for some!

De La Salle Institute - Rome

De La Salle College 4 - 13 St. Josephs CBS Drogheda 3 - 5

De La Salle College took the Louth Colleges Under 16 title back to Dundalk following a strong second half performance at a blustery Ardee. Both sides put in a great effort in difficult conditions with some super scores taken on both sides.
St. Josephs played with the aid of the breeze in the first half but it was the Dundalk school which started the brighter. De La Salle opened the scoring in the first minute through Ciaran Bellew with Joe Rogan squaring it up for Joes a minute later. However they were not to score again until the 16th minute with their opponents adding a further three points to their tally through Patrick Reilly(0-2) and Gerard Mc Sorley. It was then that St. Josephs made use of the elements and hit the long ball into their forward line with Anthony Lynch, Jake Mc Cabe and a fine Cian O Brien effort leaving the score even. In the 23rd minute St. Joes hit the first major of the game with a goal fit to grace any arena. Anthony Lynch stormed through from midfield and smashed the ball to the Dundalk net from distance. This left the goal separating the sides and this was reduced to two a minute from the interval with a Gerard Mc Sorley free.

The game was won in the first ten minutes of the second half when De La Salle scored 1-4 without reply to take a strong hold on the game with Patrick Reilly hitting the goal. St. Josephs reduced the arrears to four but the Dundalk school built on their lead with a further goal from Raymond Mulholland and points from Gerard Mc Sorley and Darren Mc Mahon. St. Josephs to their credit never gave up and in the 21st and 28th minute hit goals of their own through Jamie King and Conor Smith to reduce the deficit to five, but De La Salle capitalized on some tired legs from their opponents to hit two goals in the last minute.

Full credit to both schools and their mentors for serving up a high scoring affair. A feature of the game was some of the fine scores taken. Two in particular which warrant a mention were the goal from Anthony Lynch in the first half and a point from De La Salles corner forward Conall Smith in which he sold a number of dummies before slotting over. De La Salles victory was built on a good work ethic and they had the edge on their opponents for large sections of the game. Full credit to St. Josephs however as they kept battling right until the end and the scoreline does not fully reflect the effort they put in.

Scorers:
DLS- Patrick Reilly 2-5, Gerard Mc Sorley 0-3, Liam O Leary 1-0, Gareth Hall 0-2, Raymond Mulholland 1-0, Conall Smith 0-1, Ciaran Bellew 0-1, Darren Mc Mahon 0-1.
St. Josephs- Anthony Lynch 1-1, Conor Smith 1-0, Jamie King 1-0, Jake Mc Cabe 0-2, Joe Rogan 0-1, Cian O Brien 0-1.

De la salle took part in world maths day on March 4th. Approximately 150 of our students participated. The students enjoyed competing against international opposition and took great pleasure in beating students from far flung areas of the world. More students participated this year than ever before and we were delighted to be part of it. Our overall winner and winning the gold award was a first year , Mark Gilmore. Niall Mc Ardle was our 2nd year winner , while Aidan Mc Nally was top in 5th year .We all look forward to next years competition when we plan to get more of our students involved.
