Our 4th classes invited their parents to their very own engineering exhibition today.

4th classes showed their Young Engineer Award prototypes that they had made to solve some pressing problems that our world is facing. The children confidently explained how their prototypes work, how they are powered and what community or global problem they are solving.

The projects were incredibly innovative. Ideas brought to life by the young minds of tomorrow. We can rest assured that our future is in good hands!


Engineers Visit Our 4th Classes - November 2023


Our 4th classes are currently participating in the Young Engineers Award. This initiative involves the children thinking of a problem in their community that they would like to solve. They then collaboratively design and build a prototype of their idea. Engineers Ireland assign a guest engineer to visit each class. The Guest engineer inspires the next generation to enter the world of engineering. The children present their projects at this time also.

This week we had two visiting engineers.

Martin, an engineer from ESB visited one of our 4th classes on Wednesday. The students loved learning all about electrical engineering and were thrilled with the opportunity to show off their projects to a real life expert! Thank you so much to Martin for answering all our burning questions and for your positive feedback on our prototypes.

Here are some photos of the visit by Viswas from TOBIN Engineering today. He told us all about the different types of engineering, his work projects and who inspired him to go into engineering. Thank you so much Viswas for a very informative visit!

Well done to our budding engineers in 4th class!

Environmental Science - Sustainable Houses by 6th Class

IMG_2125.jpg. IMG_2126.jpg

In sixth class, students were learning about sustainability as part of Environmental Awareness and Care in Science and Geography. As environmental care has received a lot of attention over the years, including a recent SEAI workshop, students in sixth class were very knowledgeable on the topic. Therefore, I decided to challenge them further by making their task into a STEM challenge. I gave them the challenge of building 'Sustainable Homes' in groups. Each group researched what features make a home sustainable, for example, solar panels, insulation, wind powered energy, green houses, gardens, rainwater collection basins etc. The children then gathered as many reused recyclable materials to construct 3D homes and gardens that showcased all their sustainable features. They were challenged with creating homes that displayed indoor and outdoor sustainable features. Lastly, they decorated their houses with paint, recycled paper, markers etc. The project allowed students to take responsibility over their learning and further their own knowledge through research. Additionally, working in groups facilitated peer teaching and learning. My favourite part was it made the link between knowledge gained on sustainability and applying it to a real-world situation – building a sustainable home. The challenge led to students using their creative juices to build the best home while allowing informal discussions between peers about the environment and sustainability. Students loved the challenge and were eager to work on a similar project as soon as they finished their amazing 'Sustainable Homes'.

March 2023 - History STEM Projects

These Norman castles have moving parts using a variety of pulleys, levers and catapults. Scientific learning during Energy & Forces lessons was brought to life by imaginatively designing moving parts in the castles.


This is Trim Castle. Beware, it has cannons that work, made using balloons and card tubing! The drawbridge can be opened and closed using string.


This is Lough Eske Castle in Donegal. Look how the waves are tied together. There is a secret tunnel beneath the waves leading to an island where there was a jail! There is a moving drawbridge also.


This is Cahir Castle standing proudly on a rocky island in the river Suir. It has a moving drawbridge, a kitchen and a chapel. It also has a drinking well with a tiny bucket that moves up and down using string and card as a pulley and a crank.


This is Kilkenny Castle with numerous clay figures who worked and lived in the castle. This castle has two doors that open. The dungeon has been updated to include a light using an electrical circuit!!!


This castle was inspired by a group member's visit to the Tower of London. This is White Tower, London. There is a legend which says that when the resident ravens leave, the tower will fall. Therefore, this castle needed to fall apart! The team cleverly designed a way for this to happen using 4 open sides held together with string. Let's hope the ravens stay!


This is Malahide Castle with a moving drawbridge. Part of the roof opens to allow us to peep inside the castle!


This is Donegal Castle. It has a secret tunnel leading to a secret garden! It also has a moving drawbridge.


March 2023 - Engineers Week - Trip to Hilti


3rd & 4th class were invited to take a tour of Hilti today for Engineers Week. Hilti design, manufacture and service construction tools. We had a fantastic time exploring different areas of their super cool building wearing our high vis vests and safety googles!


Our first stop was the futuristic Hilti Customer Service Experience room. We were amazed to learn about the variety of tools they make and how they are all powered using the same battery model. We learned about different types of engineering and how important teamwork is.

We then made our way to meet another Engineer who showed us Hilti's impressive Red Bull Soapbox cart. It was very interesting to hear which materials were used for the soapbox cart and the reasons why each material was chosen. The brake was made using a 3D industrial printer. The suspension system looked very robust!

Next, we went to the Hilti Tools Service Centre. We enjoyed learning about quality control and saw the Balex machine which breaks down materials for recycling.

Last but not least, we got to use our own engineering skills as the Hilti Engineers challenged us to build bridges using lego bricks! CETNS students rose to the challenge and designed some great bridges.

We had a fantastic time today at Hilti. Thank you so much for having us and a very big thank you to Noah Markey's dad, Dennis for organising our trip. It was most inspirational.

take a look at some photos of our trip here!

There were lots of very interesting engineering challenges happening in our school this week. Click here and find out all that went on this week in CETNS!


Here is one of the challenges - Egg Drop Challenge in 3rd class

As part of Engineering Week 2023, 3rd Class took part in an Egg Drop Challenge. Everyone had two weeks to plan, design, build, and test a prototype that would protect an egg when dropped from a height.

We thought a lot about what materials we might use, and though some of us came up with amazing ideas like wind-powered arms to support a parachute, and atomic balls of energy to prevent breakage, we had to think again, as it might have been a little difficult for our parents to source these. Most of our prototypes were made from recycled materials such as cardboard, cotton wool, elastic bands, and plastic bags.
When Launch Day arrived, everybody was so excited to try out the prototypes. We had fun predicting whether or not the egg would survive, and most did! Though there were a few broken shells, we used this as an opportunity to review, refine and improve our designs - all part of the engineering process!
It was clear that everyone put lots of hard work into their prototypes at home, and we would like to say a big thank you to all of the parents and guardians at home who helped out. There are definitely some engineers in the making in Rang a Trí.

February 2022 - Maths 3D Art!

2nd class made 3D shapes such as cubes, cuboids, pyramids, and even a fish using marshmallows, spaghetti, and playdough.

The Intel Mini Scientist National Grand Final!!!!!!!

"When we arrived at the venue, Maynooth University, we were greeted with many exciting and interesting projects. We rushed to our stall and began to set up, looking forward to the day ahead. We presented our project to five judges. After the judging, we really enjoyed watching ‘The Science Show with Phil’. Our favourite experiments were when he shot paper all around the hall and when he exploded liquid nitrogen everywhere! We were seated in the front row so it felt like we were being rained on! The judges then announced the winners. Unfortunately, we didn’t win ☹. We were so proud to get this far, and honoured to represent our school in such an exciting and amazing way." by Izzy, Ella and Maisy

For History Week in CETNS, we asked children to build a monument or building of their choice using lego bricks! Our creative master builders got to work! We had a fantastic display in our school.

Around this time, the Heritage Council of Ireland put out a call asking children from across the country to get creative and showcase an element of Irish-built, natural or cultural heritage using LEGO® bricks, and the wonderful children of CETNS duly obliged. We have lots of enthusiastic Lego master builders across the school who were only too delighted to take up the challenge. We received lots of creative, imaginative, and expertly built Lego models which are currently on display in our foyer. Please have a look at some pictures below of the incredible Lego models that the children made.

The Heritage Council ran a competition across two age groups, 4-7 and 8-12, across Ireland. We are delighted to share the news that CETNS had two winners and four runners-up across the different age categories which is an incredible achievement. Our two winners were Luke Campbell ( 4th Class) and Isabella Carwood (1st Class). Our four runners-up were Ishaan Dalmia (1st Class), Liam Giusti (1st Class), Sophie Dixon (4th Class), and Jerry Luo (5th Class).

Models made by Oisin in Senior Infants (Wellington Monument), Nikki in 1st class (Papal Cross), Miar in 2nd class (Poolbeg Chimneys) and Cian in 4th class ( Newgrange ) are also to be seen in the introduction of the video announcing the winners.

Congratulations to all of them, but also to all our amazing Lego builders who made models.

October 2022 - Intel Mini Scientist - 6th classes

Everyone had a great time at the Intel Mini Scientist on Friday. Well done to all who took part. The projects were all very interesting and informative.The children were outstanding at presenting and describing the projects. Congratulations to Maisy, Ella, and Izzy (Eugenia's class) who won with their fascinating Bird Project. And congratulations also to Seb (Andreas' class) and Sam (Emmett's class) who got a special mention for their Steam Engine Project.

Maisy, Izzy and Ella were our most recent winning school team. They constructed an avian project using recycled wood and a motion sensor camera above it. The camera was linked to a phone for easy observation to make their findings. "The reason we chose this project is because we are all passionate about nature, biodiversity and birds in particular. We also thought people who care for birds would like to know which food birds prefer and is healthiest for them. What we enjoyed the most about our project was making it together and presenting our project to everyone!”.

October 2020 - Young Engineers Award Prize Arrives to CETNS!

Our Young Engineers Award winners Umiya, Daniel, Maggie and Ashkan from 4th class received their prizes today from Engineers Ireland.

We are looking forward to learning to code with Photon, our new school robot!

"In 3rd class, we participated in the Young Engineers Award. We collaboratively decided to design our project, a wireless electric car charger, which we felt was needed in our community. The project involved making a prototype while detailing the engineering process in a booklet. We presented our prototype to a visiting guest speaker engineer. For months of nervous waiting, we hoped for the best. To our delight, we received the good news that we had come in the top 6 in the country. We were all set to attend the prize giving ceremony in May 2020, but due to Covid 19, we couldn’t attend, we were in lockdown. However, we did attend the online prize giving award ceremony, which was great! For our school, we won the photon robot, which was a great achievement for us and our school. We were very proud of ourselves. We really enjoyed participating in the Young Engineers Award."

Engineers Week – 4th – 8th March 2019

Young Engineers Award Prize Winner!!!!

Huge congratulations to Cliona Magerusan (3rd class) for coming highly commended in the first ever Young Engineers Award! We were thrilled to hear that Cliona's fantastic STEM project construction of a community polytunnel was chosen! Congratulations Cliona!!!!!!!

"I was so surprised and delighted to hear that I had made it to the shortlist of the top 10% of the projects for the Young Engineering Award. For my project, I decided to construct a community polytunnel. I thought this would be useful for everyone and especially people in apartments so they could get a chance to grow organic fruit and vegetables. I was inspired by our school polytunnel where we grow lots of fruit and vegetables and share the harvest with all the boys and girls in my school. To make my project, I knew real polytunnels are made with a steel frame covered in strong plastic so for my mini-polytunnel I used a pipe cleaner frame and a clear plastic sheet. I was very proud of my finished project. I had so much fun designing and making it." By Clíona 3rd class

February STEM Challenge - Engineers Week 2019

Manga High Workshop – Feb 2019

4th class recently had a very informative ICT maths workshop hosted by Chris from Manga High. They learnt all about what you have to do to get each type of medal, bronze, silver & gold. He taught the teachers how to keep activities classroom assigned. If you want gold you had to get every single question right & be on the difficult level & get 10 ‘on fire’ questions right. You can only get a bronze on your first go! There are easy, medium, hard & extreme levels. You have to get 3 questions right to go up a level & if you 2 wrong you go down a level. We love it, go on give it a try!

Finn & Cathal, Andreas’ 4th class

Science Workshop – January 2019

Designer Minds scientists visited to host a science workshop with 3rdand 4th classes in January. The workshops introduced the children to the area of biology, specifically bacteria. The children carried out their own experiments using nutrient agar plates to test whether antibacterial handwash kills bacteria. The children will observe bacteria growing over the course of a week. We will be very interested in their results!

Young Engineers Award Projects – December 2018

3rd and 4th classes were busy bees in December working on their Young Engineers Award projects. Take a look at some of the projects that were submitted!

Last Thursday we had a visit from an engineer, Anjena, who works with Nicholas O’Dwyer Engineering. Right now she’s working on a new design for a water treatment plant in Sligo. We presented the projects we did for Young Engineers Award. Our group built a bridge over the Ashtown Train Station & she told us how to add side supports. The point of the projects is to look at the community and see what’s not working and make improvements. We then needed to make a 3-D model so we used K’nex for our bridge. She told us the sides and slope needed to improve and she helped us by showing us the side supports.”

Intel Regional Finals – 5th Dec 2018

On the 5th Dec 2018, we went to ITB to compete in the Intel Mini Scientist competition. Three of us were invited last year so we had a good amount of experience. On the day, there were 90 different schools battling for one of the 16 places in the national finals. Our project was on biometrics. Conor Walsh (me), Charlie Coffey, Jack Brady and Abdullah Anwar made the project. We were judged around 9:45am and the judge loved our project! She stayed around for a long time to listen to every last word we had to tell her! I had a good feeling that we were going into the next round, At 11:30am, we had a science demo by a scientist named “Scientific Sue”. She did the same show she did last year on bubbles. Even though she had the same content, it was fun to watch. After lunch it was time for the results. We didn’t make it in, but a few of the kids we were chatting to made the cut. Even though we didn’t make it in, I still had a great day. Most people who viewed our project liked it and wished us luck.

Thanks to Liz for giving us the opportunity to compete in this competition and thanks to our parents for arranging meet-ups and waiting with us on the day.

Intel Science Fair – 15th November 2018

The Intel mini scientist exhibition took place in the hall on the 15thand a great day was had by all. Fifth and Sixth class children presented their projects and the rest of the school learnt all about their various experiments and findings. Many parents joined us on the day along with the Intel judges. Congratulations to our winners but particularly a very special congratulations to all the children who presented on the day, a lot of work went into the preparation for the day and we hope you are as proud of yourselves as we are. You can view some photos of the day http://www.cetns.ie/News/Science-Fair-2018/814/Index.html Thank you to all who helped with this event,

The winners were Charlie, Conor, Abdullah, and Jack from Liz's class with their project about Biometrics.

The runners up were the Mysha, Shaheera, Aamna and Maheen from Aoife's class with their project about Mnenomics.

Well done.

Marine Biologist Visit for Science Week – Nov 2018

A workshop took place in 3rd class all about marine litter. Lorraine, a marine biologist recently spent 6 months working in the oceans beside Hawaii helping to clean up plastic. She told us facts about how big sharks are. She also told us about a whale that died and scientists found 11 plastic bags inside the whale’s stomach. By 2050, she said there would be more plastic in the ocean than fish! So I am going to be more careful with plastics to stop marine litter.

The Whole School STEM Project returns!

The STEM project for January is to make any winter themed creatione.g. snowflake using matchsticks and marshmallows, igloo using sugar cubes, a snowball launcher. The options are endless! We look forward to seeing the fantastic projects.


Here are some Roald Dahl Day STEM Projects.




As National Space Week runs from the 4th to 10th of October, our STEM project for October will be to make a space themed creation. As always we look forward to seeing your wonderful ideas!

Fantastic creations for our Space themed Stem Challenge

Ireland’s Ingenious Engineers Show with Scientific Sue.

This highly creative and exciting science and engineering show explores some of the amazing scientific discoveries and engineering feats endeavoured by some of our amazing Irish Scientists over a period of 350 years: Which of the amazing engineers was responsible for the creation of hot chocolate? The discovery of carbon dioxide? Who found out how to turn a gas into liquid? This process now allows us to send astronauts and rockets into space? Whose invention saved the life of Neil Armstrong the year before he landed on the moon? Which field of engineering will give us the excuse to make ice cream? Explode gases? Race balloons? Save people’s lives?

As always, lots of volunteers will be needed to help Scientific Sue on, yet another one of her mind-boggling, energetic journeys of scientific discovery.

STEM Family Project

Castleknock Educate Together has introduced a monthly STEM Family Project. Parental involvement is a very important part of our ethos and we feel STEM Family Projects are the perfect way to create meaningful connections between the school and home for science, technology, engineering and maths processes.

The Engineering Design Process is:
1. Ask - what’s the problem?
2. Imagine- choose a solution.
3. Plan - draw it.
4. Create - make it.
5. Improve - make it better.

January’s challenge was to create an object using sweets in its construction! Teachers were blown away by the creativity and enthusiasm shown by the families of CETNS. We also received lots of very interesting photos of the stages of the engineering process.

February’s STEM Family Project is to create a Fairtrade themed object using recyclable materials. This challenge will link in with our whole school focus on Fairtrade this month.

We look forward to exhibiting our February STEM Family Projects in our school during Engineers Week (26th Feb - 2nd March)
