Young Scientists !

Thank you to Emily and Lucy from Ardgillan Community College for presenting their BT Young Scientist project to Ms. Walsh’s 4th class.

Emily and Lucy’s project was about the use of micro plastics in facial washes.

They were very informative and answered lots of questions. They were deleighted to hear all about Ms Walsh’s class project which was at the BT Young Scientist Fair. 

Primary Science Fair

Ms Walsh’s fourth class took part in the Primary Science Fair at the RDS on Saturday, 13th January.

The RDS Primary Science Fair showcases STEM investigations (science, technology, engineering and maths) undertaken by 4th-6th class children. With a core focus on children’s skills development, it brings together teachers, parents and students to showcase class projects, share experiences and learn from each other. The primary science Fair takes place alongside the BT Young Scientist Exhibition.

The fourth class pupils, teachers and parents had a great day at the fair. The children had studied how cranes work and  built a number of model cranes from recyclable materials. Thank you to Fergal, Jodie’s grandad for building us a crane from wood.

The pupils impressed the judges with their knowledge and enthusiasm about cranes and they also taught the  judges some Gaeilge!

During the day in the RDS the children had an opportunity to experience some presentations and films on STEM related subjects. They visited a number of exhibitions and really enjoyed the experience.

Well done to all and a big thank you to Ms Walsh and Ms 0′ Brien for facilitating this work with the children. .


Can you Balance?

In order to balance when you are standing your centre of gravity should be over your feet. When you are standing and bend forwards your centre of gravity starts to move forward too. Normally, you’d compensate by sticking your bum out behind you.

In this experiment you stand with your back and heels against a wall/door. Drop a coin on the floor in front of you and try to pick it up without falling over.

With the wall/door there, this is impossible, so you fall over.

5th Class Visit to Balbriggan Community College

The 5th class children from St Molaga’s were invited to visit Balbriggan Community College. The children were split into different coloured groups on arrival. They then, with their group leader, visited the art room to make gory cuts out of paint, glue and plaster, the tech room to look at robots, the science lab to make fire and dissect a lambs heart and finally to their new amazing gymnasium to jump the high jump and climb the climbing wall.

The children got a real flavour of what secondary school in Balbriggan Community College will be like if they chose to go there.



We carried our some fun expeirments today to learn about sound!

We used tuning forks dipped into water to show that sound causes vibrations!

We used elastic bands to create mini string instruments!

We used straws to make mini wind instruments!

Finally we made a ‘string telphone’ to test whether sound would travel along a piece of string! It did.

We made lots of of noise! (Click on the link to see more pictures.)


Electrical Circuits

We had great fun investigating electricity and how electrical circuits are formed!

We used insulators and conductors to make working torches and fans. We investigated how conductors can attach positive and negatively charged wires together to create and electrical circuit! The conductors attached wires together and sent electricity to different areas on the circuit. The wires were protected by plastic insulators.

It was so exciting to watch the light-bulbs light up and the fans begin turning when the circuit was complete!


Science- testing the strength of Materials: paper

In December 2016 we did a science project to test the strength of paper. We had to make a bridge of newspaper and see how many copies it would support. We separated the tables, leaving a gap wider than a copy. Then we placed a sheet of newspaper across the gap, to keep the paper in place we put baskets on each end for support. Then we started putting the copies on but we got around 50. Then we thought about folding the newspaper in half and putting on tape instead of baskets. It made it stronger and we got 77.

Experimenting with materials

We learned about different kinds of materials and their properties. We carried out an experiment to test some materials. We tested a tennis ball, a sponge ball, a ball made from plasticine and a ball made from rubber to see which one would bounce the highest. We wrote out the experiment and carried it out three times to make sure that it was a fair test. We discovered that the tennis ball was the bounciest ball.
