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 ‘Engineering a Cleaner World’. We chose to research wave energy, focusing on the prospect of harnessing it in Strandhill. We chose this because

  • It’s a relatively new source of renewable energy
  • It would be good for the west coast
  • It’s local.

Part of the project was getting 6 K’Nex kits in your school for 2 weeks. We had lots of fun with them!




The project runs for 4 months, from December to April. We have had learned lots so far and have put a lot of our project together.

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 it. He told us that the movement of the waves cause pistons move in and out, which in turn causes the motor to turn and the generator to work.


He told us that if you want to be an engineer you have to enjoy doing Maths.

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.

We made an Oyster. It is an oceanic device that harvests wave energy when the waves push the lid up and down! This moves pistons in and out, spinning a motor that creates energy. The energy then runs through an underwater cable into a power plant that converts it into electricity that is then used to power our homes!

Our group decided to make an Oyster. An oyster is a machine in the water that is used to generate electricity. Our Oyster was 3-D and we used K’Nex to build it. We really enjoyed using the K’Nex to build out Oyster.

We did a project about wave energy. We got the K’Nex kits on Monday 7th March. For the first day we were allowed to build anything. By the second day we had the choice of building either a Pelamis or an Oyster. We did individual creations at first. Vita built a Pelamis, Shauna and Louise both built Oysters. Later we all took Louise’s plan for an Oyster. It turned out really well. We all love working with K’Nex!!!

We built an Oyster. It is a machine that is built on the sea bed. The moving of the waves cause the top of the Oyster to move in and out, causing two pistons to move in and out. This pushes pressurised water into a small tube. The pressurised water is pumped onshore to a generator which produces electricity. We built a model of this out of K’Nex!

For our K’Nex experience we had to build a pelamis or an oyster. Our group Neasa H, Hannah B and Claire Mc V, decided to do an oyster. For the first step we had to design a plan of what we were doing. We used our plans to construct our Oyster out of K’Nex. We replaced lots of pieces to improve it. Finally we added the motor to make our creation work. Once we had that done, we got our picture taken with our oyster. We were then recorded talking about what it was and how it generates electricity .We enjoyed our experience with the K’Nex!!! J

There are two people in our group, Claire and Meadhbh. For the K’nex challenge we built a Pelamis. A Pelamis is like a giant sea snake in the water. When the water pushes the pistons in and out the movement generates electricity. We really enjoyed building the Pelamis. We also learned a lot about wave energy. We were very pleased to see that when we finished building it, it moved!
