Santa’s Visit

Santa arrived in school today and settled himself in the Library to read a few books but he was soon joined by all the girls and boys in Infants. He chatted to each small  groups , asking if they were going to leave him any food on Christmas Eve. He then gave them a little surprise  for being so good in school. Here are a few pictures from Ms. Doyle’s class as they visited.

 

 

 

PTA Dance

The PTA Annual  Dance was held in the Crowne Plaza Hotel last Friday night with  a drinks reception  followed by dinner and live music. There was a large number of  raffle prizes and we want to thank the companies and individuals who so were so generous in providing sponsorship .  Well done to Ann Delaney and her team for organising such a great night.

6th Class Experiments

6th class conducted three experiments:

Bernouli’s Principle...How planes fly using a ping pong ball and a balloon

Bernoulli’s principle helps explain that an aircraft can achieve lift because of the shape of its wings. They are shaped so that that air flows faster over the top of the wing and slower underneath. Fast moving air equals low air pressure while slow moving air equals high air pressure. The high air pressure underneath the wings will therefore push the aircraft up through the lower air pressure.

Centripetal Force  using a coin inside a balloon

The shape of the balloon makes the penny move in a circular path – otherwise the penny would want to continue to move in a straight line. Another force to consider is friction. There’s very little friction between the edge of the penny and the balloon. More friction would cause the penny to slow down and stop.

The real force in action here is called centripetal force, which means center-seeking. This is a force that is always directed toward the center of the circle and is actually responsible for keeping the penny moving in a circular motion inside the balloon.

 Static Electricity , using hair and balloons

Rubbing the balloons against the woolen fabric or your hair creates static electricity. This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against your hair or the fabric they become negatively charged, they have taken some of the electrons from the hair/fabric and left them positively charged.
