In this experiment we investigated the impact of salt on ice. We placed ice cubes in a tin can, laid the string on the ice, added salt and after approximately one minute we pulled the string out of the water with all the ice cubes attached.
When salt is sprinkled over the ice, it lowers the ice’s freezing point and causes it to melt. Water around the ice forms and then the string sinks into the ice.
Challenges included:
Francesca gave very interesting workshops to 4th & 5th class and then 6th class. She brought examples of different artefacts and show the children some examples of the types of materials used for clothing during the different Ages.
It was a great start to Science Week 2022!
Their work over the course of the year included encouraging wellbeing within the outdoor classroom, learning where your food comes from and how to support Irish, as well as learning how to grow, cook and eat your own food!
For the past couple of weeks 1st & 2nd class have been learning about apples.
From looking at the different apple varieties, to how they are harvested and creating an excellent apple harvest display they now have a great deal more knowledge on a favourite fruit for many.
In recognition of their hard work, they all got apples from the Apple Farm in Cahir. The variety they received was ‘Tipperary Pippen’.
The third and fourth class pupils recently investigated the importance of good hand washing and the results are clear to see in the photos below. The washing techniques which were compared were: ‘splash & dash’, ‘quick wash’ and ‘hospital wash’.
Mr Franklin’s class were challenged with creating the tallest ‘skyscraper’ possible using newspaper. Some fantastic constructions were created with groups with the highest skyscrapers reaching the dizzying heights of 47 and 45 inches!
Experiment 1: The pupils looked at how a simple Carbon Dioxide fire extinguisher works.
Firstly, baking soda was added to vinegar in a jug. This created a reaction where carbon dioxide was produced. Due to the fact that carbon dioxide is more dense than air, the carbon dioxide stayed in the jug for the most part (although it was not visible).
Pupils where then able to ‘pour’ the carbon dioxide onto a candle and extinguish the flame.
Experiment 2: Hot Water vs Cold Water
In experiment 2 the children observed how hot water is less dense than cold water. This was demonstrated by placing a glass of hot water on top of a glass of cold water. The hot water (which had green food colouring in it) stayed on top of the cold water (which was blue). To further prove the theory, we repeated the steps of the experiment but this time placed the cold on top of the hot water. In this instance, the cold water rushed downwards and mixed with the hot as the hot itself would have initially have been trying to rise.
