Rang a 3 are learning about Heat. We predicted and measured 3 different temperatures around the school. We learnt about what makes good conductors and insulators.

We are learning all about the Titanic at the moment. We are busy constructing Titanics in groups.

Rang a 3 enjoyed litter picking on Castle Street this Tuesday.

Rang a 3 went to a talk with Alan Nolan in Dalkey library on Monday. He was brilliant. He had inspired our writing and drawing.

We had a great time picking litter for our annual spring clean. Each class covered a different area of Dalkey, so we had a great spread across our locality. Well done for keeping our town tidy boys!

Second class did a great job for this year’s National Spring Clean, up and down St. Patrick’s Road. Well done boys!

A great way to visualise the water cycle in action in our classroom!

The much-anticipated annual clash, between the sixth class boys and the staff was a great spectacle. Well done to all who took part, particularly to the staff who narrowly won by 17-16.

Many thanks to Ms. Crowley for setting up a scavenger hunt around the school to find letters, that made a ten-letter word!

Well done to everyone who took part in this year’s penalty shoot out. And in particular, to the two finalists who made it through to Friday’s final - maith sibh!

The boys had a great day up Killiney Hill to kickstart Active School Week 2026.

The boys had a super time in the annual penalty shootout for Active Week! Congratulations to the boys who got through to the final round from each class and a special congratulations to our fifth class pupil who was the overall winner!

The boys had a fantastic time cheering on Rang a Sé as they went head-to-head with staff in our annual basketball match for Active Week! Well done to Rang a Sé who played brilliantly - and a special congratulations to the staff team who managed to pip them at the post for a very close 17 - 16 point win!

This week our Green Schools committee had the opportunity to test their skills and brush up their knowledge of rubbish sorting and responsible recycling through the ‘Bin it Better’ workshop. The boys impressed our visitor with their existing knowledge and learned a lot about how they can encourage people around them at home and in school to “Bin it Better”. Well done boys!

The whole school completed in a penalty shoot out on Tuesday. Two boys from every class will compete in the final on Friday.

In our recent ASF survey we could see that our students are heavily involved in sports with outside clubs. At Harold Boys' N. S. we think this is fantastic and want to continue to encourage outside school sports and develop links with these clubs where possible.

The results are in for our Active School Flag parent survey. Thank you to the 30 parents who completed it.

Only 33% of parents said that their child received PE homework. Teachers will give an activity sheet every Wednesday that must be signed by parents. 73% of parents have not visited our ASF page. We
