Target Boards

We like using Target Boards to revise different types of numbers which are written in many different ways.


Maths Table Quiz

During Maths Week we all enjoyed a Maths Table Quiz in our classrooms. We worked in small groups and had great fun working together on the answers to the questions which were shown on our Interactive White Boards.


Do you have Maths’ Eyes?

During Maths Week we became very aware of evidence of Maths all around us.

We hadn’t really noticed before but when it was brought to our attention, we noticed Maths everywhere! We had lots of posters around the school illustrating Maths in our environment. We discovered Maths everywhere!!

Maths Trails

Third and Fourth Classes really enjoyed doing a Maths Trail around the school and the school grounds.

Fifth and Sixth Classes also enjoyed a more challenging School Maths Trail.

Who knew Maths could be so much fun?

Science Presentation in Beaumont Hospital by the Royal College of Surgeons to St. Fiachra’s SNS students

It’s not every day that our students are invited to Beaumont Hospital  for a Science Presentation by the  tutors of  the Royal College of Surgeons!

St. Fiachra’s 6th class students put on the white coats and surgical gloves and participated in a myriad of fascinating scientific experiments. They got the opportunity to use various items of medical equipment. Everybody was enraptured by this experience! A fascinating day for our students!

Design and Make a Car Ferry

Each  group of four children designed and made a car ferry. The car ferry had to have a ramp for cars and lorries and had to be capable of holding passengers and ten play cars. Obviously, it also had to float! We tested each car ferry in a large container of water to make sure that each group had met the criteria given! We had lots of fun!

Making Oobleck

Oobleck is a weird substance!!

Oobleck is a non-Newtonian fluid; it has properties of both liquids and solids.


If you hit the substance with force, it becomes a solid.

If you slowly lower your fingers into the substance, it becomes a liquid.

Weird, eh??

Here are the ingredients you need to make it:

  • cornstarch / cornpowder
  • warm water

We used three parts cornstarch and one part warm water. Mix together.

An Electro-Magnet

Want to turn a bar of metal into a magnet? We were shown how to do this by this young scientist!

Firstly, wrap copper around a bar of metal. Next, connect one end of the copper wire to a switch. Then, tape down the copper wire so it doesn’t fall out of place. Finally,  flick the switch and the bar has magnetic properties.

Making a Lava Lamp

See how easy it is to make a Lava Lamp. The boys mixed oil, water, food dye and an Alka-seltzer tablet in a bottle and admired the chemical reaction! Cool!!IMG_0475 IMG_0480 IMG_0481 IMG_0483 IMG_0489 IMG_0490

Reaction of Baking Powder on Malt Vinegar

Watch what happened when baking powder was put in a balloon and dropped in on top of a bottle of malt vinegar!! Their chemical reaction created a gas which inflated the balloon!  Wow! Almost like magic!!

Making Slime!

Want to make slime? Mix cornstarch and hair conditioner! Success!

IMG_0528 IMG_0531 IMG_0532 IMG_0534A lovely messy job!

One way to make plastic

We were fascinated to see plastic being made out of milk and vinegar. The milk and vinegar were heated in the microwave and then mixed together until small lumps started to form. Food dye was added.  The lumps were shaped and left to cool overnight! Job done! Plastic made! We were amazed!IMG_0463 IMG_0465

Using iPads

Children researching for their projects using the school’s newly acquired iPads!! Everyone enjoys  iPad time!

Designing and Making a Hovercraft

It’s amazing what we can design and make with a bottle cap, BluTac, a CD and a balloon!! Yes, can you believe that a hovercraft can be made using these simple items?! When everything is assembled, put the inflated balloon and watch the hovercraft glide!!! FabIMG_0466 IMG_0467 IMG_0468 IMG_0469!!!

The effect of washing-up liquid on food dye

Washing up liquid really does work!! We dropped different coloured food dyes into a saucer of milk. We were fascinated to see the food dye move away from the washing-up liquid when the washing-up liquid was dropped slowly onto the milk using a cotton budIMG_0473 IMG_0470 IMG_0471 IMG_0472 IMG_0473 IMG_0474

Volcano Erupting

Wow! A volcano eruption in the St. Fiachra’s Senior school yard. We really enjoying watching a homemade volcano erupt spectacularly – thanks to the chemical reaction of  baking soda and vinegar! Very impressive! You can understand why this experiment took place outdoors!IMG_0535 IMG_0536 IMG_0540 IMG_0542 IMG_0545 IMG_0547 IMG_0549 IMG_0551
