Today the boys and girls of 1st class were experimenting with objects to see if they would sink or float. For each object we did a prediction beforehand to say whether it would sink or float when put into the tub of water. Then we carried out a test to see if our prediction was correct.
Today Eric Dempsey, the well known bird expert visited our school to tell us all about birds.
He told us lots of interesting facts about birds, and he showed us some big and small feathers and a Barn Owl’s wing.
Did you know that an Owl’s wings are almost silent? That’s how they manage to sneak up on their prey!
Eric also told us all about the Swallow’s incredible journey to South Africa. Swallows leave Ireland and fly across the ocean and over the Sahara Desert to a warmer climate with plenty of food. We were amazed that a bird so small, with a brain the size of a pea, can fly so far.
Eric showed us many pictures of the different birds that live in Ireland.
The children of 1st class made Rainbow Spinners today using the colours of the rainbow as part of the Discovery Science Program.
Using a battery and a small motor they made the spinner spin really fast. You then see light reflected from all its colors, but your brain cannot separate them. So you see a mixture of all colors, which is white. It was fun!
Today the 1st class children made ‘Wag the Dog’ levers as part of the Discovery Primary Science Program.
When you push or pull one part of a lever you make a push or pull on another part in the opposite direction. Levers can be used to lift heavy weights or change the direction of a force (e.g. you sit on one end of a seesaw and the other end goes up; you press down on a screwdriver and the lid comes up).

The children made ‘Wag the Dog’ stick its tongue out by using its waggly tail as a lever!
Today the 1st class children tested their colourful snake spirals they made as part of the Discovery Science Program. They hung some of them over a warm radiator to show that warm air is lighter than cold air. The warm air will rise and make currents. These currents will then make the snakes spin. It was fun to watch the snakes spin caused by the rising warm air.
Today the children of 1st class made Acrobatic Clowns to learn about the centre of gravity as part of the Discovery Primary Science program.
All objects have a balancing point, called the centre of gravity. The lower you make the centre of gravity the more stable the object is or the better it will balance. First they tried to balance the cardboard clown on its nose – it was difficult.
Then they lowered the centre of gravity by attaching coins to the clowns hands and it balanced much better.
Welcome to the school’s Science Zone. This zone will be used to display some of the work the school is doing as part of the Discovery Science Program.
