We used a balloon to make an aluminum can roll across a table. How? We rubbed the balloon on our hair really fast. We held the balloon near the can and it began to roll without anyone touching it! Why? … Continue reading

Senior Infants went to the school library today and had a look at the new exhibit in the School Museum. We looked at pictures of some computer game consoles and discussed which ones we thought were older and which ones … Continue reading
Well done to all the children who took part in the semi-finals and final game today in Aughrim Street Sports Hall.
Week 4: Match Reports
SEMI FINAL 1:
ESTONIA 2 Kelly Larkin (1 goal), Florin Popa (1 goal) V CHINA 1 John Campion (1 goal)
Estonia edged out china in a hard fought but fair first semi-final. The fans were in good voice- chanting for both teams. Kelly Larkin, who was on loan to Estonia took the first goal but John Campion pulled one back from China. In the end, despite some heroic goalkeeping from Daryl Stokes, a second goal from Florin Popa sealed victory for Estonia and a place in the final.
5th/6th class got eggs-perimental this week with a super experiment.
We put a hard boiled egg in a glass of vinegar for four days to see what would happen. We made great predictions first.
After four days, the egg had lost its shell – well, actually, the egg’s shell dissolved in the vinegar. We learned that this is because the eggs shell is made from calcium (just like our teeth and bones) and the vinegar is an acid that breaks the calcium down.
It’s this reaction that caused the limestone in the Burren in County Clare to form the way it is – because of the acid in the rain. The limestone is a sedimentary rock, formed from the bones of creatures like fish and animals over thousands of years – so it’s also made of calcium.
Hmmm. now we know why fizzy drinks are so bad for our teeth – it’s the acid that wears away our lovely teeth, which are formed from all that great calcium in our bodies. The fizzy drinks are full of carbonic acid!
We are designing our own experiments now to test which acids are strongest – we’ll carry out our tests next week – watch this space!
This month in Science, we learned about different ways of moving objects. Pulleys are used to move heavy loads with little effort. They are simple machines that have been used for thousands of years. We learned how they are made, how they are useful and we even made some working ones ourselves.
Here are some things we learned about pulleys:
Pulleys are simple machines designed to make life easier. They involve wheels that turn using a chain, rope or cable of some kind.
They work by pulling in a direction that is different from where the load being moved is going. By pulling down on the cable, the load goes up.
By pulling down on the rope, the load goes up.
· Pulleys have been in use for thousands of years.
· Modern pulleys use a wheel instead of a branch or a beam of wood. Thisis because there is less friction when a rope pulls over a wheel than when itpulls over a branch.
· Pulleys often use more than one wheel.
·The more wheels in a pulley arrangement, the less force is needed to lift the same amount of material.
· Pulleys are found in lifts, sash windows, cranes and some types of window blinds.
· They are also found a lot in the work-place.
The Afterschools clubs finished up their 4 week block this week.
3rd/4th classes had great fun learning tunes on the tin whistle and doing sports with Mr.Gallagher.
5th/6th class have been getting crafty the last few weeks with Ms. Leonard. They produced some lovely ribbon weaves. They finished off this week showing their creativity by producing a lovely range of Easter Art – from translucent coloured Easter Eggs, to origami rabbits, inventive Easter characters and mixed material Easter Eggs.
Look out for more clubs after the Easter break.
