4th Class – ‘Plastics in the Ocean’

As part of work for our Discover Primary Science and Maths Award, our 4th Class men in Rooms 20, 21 and 22 have completed a projected entitled ‘Plastics in our ocean’. The boys have looked at some of the harmful effects of polluting our oceans. The boys found out that by 2050, there will be more plastics in the sea than fish. Plastics in the ocean can cause great damage to wildlife, with thousands of marine animals killed annually due to entanglement or ingesting plastic materials. They then used the findings of their investigations to start a campaign around the school, looking at our use of plastics, and encouraging us to search for alternatives. Among the suggestions are as follows:

  • Use reusable cups instead of plastic or cardboard
  • ‘Ditch the straw’ – replace the straw with reusable materials
  • Reduce the use of plastic bags when shopping
  • Not using toothpastes that contain ‘microbeads

Here are some images of the excellent display that our boys have created in the alarge hall on the topic.

5th Class – ‘Weather Watch’

Over the past week, our 5th class men have been carrying out a ‘weather watch’. We have really enjoyed working as scientists and meteorologists. Before we could begin with this project, we had to understand how weather equipment was used for measurements. We then built our own anemometers (to measure wind speed), rain gauges (to measure rain) and thermometers (to measure temperature). We went out to different parts of the school yard each day to record our findings, and represented them through graphs and images. It was very exciting and interesting to get the opportunity to work in this way.

Professor Donal O’Shea Visit

We were delighted to welcome Professor Donal O’Shea (known for his work on RTÉ’s Operation Transformation) to the school on 30 November 2017. Professor O’Shea was speaking to the boys as part of a ‘Science Foundation Ireland’ initiative. We learned about the different ways in which we can keep our bodies healthy, how to exercise properly, and how to eat certain foods in moderation. The boys were then delighted to take part in the ‘Q&A’ session with Professor O’Shea at the end of his presentation.

We were also delighted that Professor O’Shea stayed around to deliver a similar presentation to parents and other members of the community in the evening. Thank you Professor O’Shea.

Junior Infants: Science Experiment

Last week the boys in Room 3 carried out an interesting experiment, which was prompted by our recent weather! It was called “The Snowman’s Coat”.

Having discussed and shared the fun they had in the recent snow, the boys described their many and varied snowman-creations. As they have all since melted, the boys were  asked to think about how they might get their snowmen to last longer! They came up with some very interesting ideas, among them…..

  • put him in the fridge
  • wrap him in an ice-pack
  • make him beside the wall/under a tree
  • put a blanket around him
  • give him a coat and hat

So we decided to carry out an experiment to establish what would happen if we gave the snowman a coat, as some boys suggested. We brought in some snow from the yard and made two small snowmen in our classroom. We tried to keep them the same size, so that it would be a fair test.

We then wrapped one snowman up in a “coat” and placed them side by side at the top of the room. The boys suggested that we would not place them near the radiator or under the light, in the hope that they would last much longer!

The boys predicted what they thought would happen, giving their reasons why. We kept a close eye on our “new classmates” during the day, but before long it became clear that one saucer was filling up with water a lot faster than the other!

Yes, the snowman wearing the coat lasted longer, but can you tell why?

Senior Infants- Science- Space

During the month of January, Senior Infants were learning all about the theme ‘Space’. It was a very popular theme because it was so interesting and lots of fun! We watched some Youtube clips of astronauts brushing their teeth and washing their hair in a space station!! We learned that everything floats in the space station because there is no gravity. We then carried out an experiment to explore gravity on Earth. We held two bottles of water at the same height and predicted which bottle would hit the ground first. We had many different predictions so there was a lot of discussion. We varied the weight of the bottles and also dropped them from different heights to ensure it was a fair test. Check out our photos below to see the results!

We had great fun launching a rocket. We blew up a balloon, let it go and noticed what happened. Next, we discussed ways in which we could control the path in which the balloon was travelling. We then connected the balloon to a piece of string and launched our very own space rocket in the small hall!

We carried out an experiment to discover why there are craters on the moon. To make the moon’s surface we put flour and cocoa powder in a big tray. We used pieces of plasticine as meteorites and predicted what would happen when we dropped them onto the moon’s surface. We changed the size of the meteorites and dropped them from different heights to see if there was any difference in the craters. As you can see making craters was quite messy but great fun!

At the Role Play area we had the opportunity to take on the role of an astronaut in the Space Station.

At the construction area, we made space ships, the planets, rockets space stations using Connects and Lego.

At the Creative Station, we created our own space rockets and flying saucers.
