Today we did a science experiment for Science Week. We got balloons and a knitting needle for the experiment. We blew up the balloon until there was some dark balloon left at the bottom and at the top. Then we pushed the knitting needle through the bottom of the balloon first and then it came out through the top. The balloon did not burst

This morning we did a science experiment for Science Week. For this experiment we needed food colouring, cotton wool, full fat milk, washing up liquid and some shallow plates. We had to pour the milk into the plates and let it settle. Then we poured the food colouring into the milk. We had yellow and red food colouring. The food colouring settled on top

Last week we went on a minibeast hunt. We followed the Conservation Code: Search care f u l l y Handle animals with care Replace stones and logs Observe, draw and re c o rd if possible, rather than handling Return animals to habitats as soon as possible
What is the Xperience Engineering Challenge? Xperience Engineering is a program run by Engineers Ireland for primary schools. The project is divided into 2 categories, 3rd/4th Class and 5th/6th Class. The top 20 projects from each of the categories will be chosen to represent their school at the Xperience Engineering National Final in the Helix in Dublin in June. This years theme is

What is an Oyster? The action of the waves moves the device up and down. This action activates the pistons causing high pressured water to be pumped to the shore, through an under water pipeline. Onshore hydro-electric generators convert this high pressure water into electricity. By Shauna, Seán M, Aoife, Carla, Sophie
What is a Pelamis? This Pelamis is a huge “sea snake” in the water. It generates power in the hinged joints that connect its cylindrical tube sections. As the wave move the joints up and down, and side to side, hydraulical rams drive an electrical generator. The electricity is carried to shore via a sub sea cable. In a Pelamis the pistons move

Miss Hynes asked the class to bring in things like toilet rolls, plastic bottles and straws to construct a model of a wave energy generator. The choices were a Pelamis or an Oyster. Most people made a Pelamis. When everyone had finished making their Oyster or Pelamis, they left them to dry at the back of

Micheál O’ Halloran is a mechanical engineer. He came into our classroom and spoke to us about the engineering that is involved in things like Avatar and Grey’s Anatomy. He told us all about the different engineers that are involved in making a rollercoaster. He explained to us how a Pelamis works. We learned that there is a motor and a generator inside

We built an Oyster. It is the same shape as a suitcase. It is a wave energy generator. The top of it moves forwards and backwards in the waves. We hooked up the motor and it finally worked.
Our group built an Oyster out of K’Nex for our Steps Xperience Engineering Project. An Oyster is an energy producing product. It moves up and down with the waves. It is set on the seabed close to the shore. We used a motor to get our K’Nex Oyster to move up and down. We had a lot of fun using the K’Nex kits.
