Sound in 2nd Class

Sound is an energy, caused by vibrations that makes sound waves.

We completed a dancing rice experiment to see sound vibrations. We made ‘String telephones’ to hear sound waves.

We investigated which material would be the best sound insulator. We measured how far away from the sound we needed to walk before the sound disappeared when blocked by each material. We predicted that the cardboard box would be the best sound insulator and we were right!

Some materials allow sound to pass through them easily. Other materials absorb sound.

Incredible Edibles – Senior Infants

This week we worked together to plant all of our seeds from Incredible Edibles! We now have such a variety of lovely fruits and vegetables growing in our garden. We sowed strawberries, potatoes, chives, lettuce, spinach and turnips. We will be busy caring for them over the coming weeks and can’t wait to watch them grow!

Design a Bridge Challenge

Task: Design a bridge

Method:

Using blocks, paper, books and crayons to test we designed bridges to see which ones were stronger and could hold the most amount of crayons. We manipulated our structures to increase their strength by folding the paper used, using double layers of paper, creating arches and structures for extra support.

Conclusion:

The material from which a structure is made is important but you can strengthen a material by changing is shape. Bridge designers often use different shapes for example: arches and triangles. The curve of the arch spreads the load on the bridge and makes it stronger.

 

Which Material Absorbs Best?

Spring showers can only mean one thing for our floors inside our homes…PUDDLES! First class put their thinking caps on today and came up with an experiment that would test which material would clean up puddles best. They made a prediction and then carried out the experiment to establish a result. Each of the children made sure to measure the water and the size of the materials carefully. It is so important that each test is fair so that the result is accurate.

Not only did first class discover whichmaterial absorbed best, they also discovered that playing with water is lots of fun!

GLOBE Project

Our fourth and fifth classes were getting started with some cloud observations in preparation for our GLOBE project this year. GLOBE is a project run in conjunction with the EPA, An Taisce and ESERO, the European Space Agency.

The project monitors aerosols and air quality around the world. Our young scientists were practicing their skills at cloud observation and classification. They will be recording their results  online and sharing them with schools and scientists around the world.  Here you can see them hard at work.

 

Spring Hunt- Senior Infants room 2!

 

Today we went on a Spring Hunt around our school grounds. We worked in pairs and used a checklist to help us to spot as many signs of Spring as we could, it was so much fun!

Signs of Spring! Room 3

We had great fun searching for signs of spring this morning around our beautiful school grounds. We had a checklist to complete with our partner.  We found insects in the bug hotels and a frog splashed in the frog pond. We saw daffodils, crocuses, catkins and snowdrops. We saw birds returning from warmer countries and we even spotted a nest in a large tree.  We were lucky to see a squirrel from our classroom window yesterday that must have awoken from hibernation.
