The younger children really enjoyed the visit of Scruffy’s Pet Store to Togher N.S. The children were delighted to meet and learn about wonderful animals and reptiles that were brought to the school.
We were delighted to visit Carrigdangan Wind Farm. Mr. David Egan the Senior Operations Manager explained how the wind farm and sub station operated and how the electricity was generated and added to the national grid. The children enjoyed the walk through the wind farm and the opportunity to see the inside of one of the turbines.
The children in 3rd and 4th class have been learning about The Wright Brothers and the first powered and sustained heavier than air flight in 1903. The children discovered that the brothers completed many experiments with different wing shapes and that they used a wind tunnel to study the effectiveness of these wing shapes.
As a science experiment the children have tested different wing shapes to discover which wing shape creates the greatest lift. After a number of failed efforts our latest wing shape was ready for testing in our wind tunnel (a piece of string and an old hairdryer) The children were delighted to finally see wing lift in action.
The children in Miss Daly’s class really enjoyed their latest science experiment, They loved watching the raisins dance in the soda as the bubbles attached to the raisins and lifted them up.
The Science behind The Dancing Raisins: When the raisins are dropped into the soda they sink to the bottom of the glass because they are more dense than the soda. But the carbonated soda releases carbon dioxide bubbles and these bubbles love to attach to the rough surface of the raisins. They act like tiny floatation devices that lift the raisin to the surface of the water. This is due to an increase in buoyancy.
Once the carbon dioxide bubbles reach the surface of the soda they pop and the gas is released into the air. This makes the raisin lose buoyancy and fall back down to the bottom of the glass.
This continues until all of the carbon dioxide has escaped and the soda is flat.
STEAM stands for Science, Technology, Engineering, Art, and Maths. We love a STEAM challenge here at Togher N.S.
The children in Miss Daly’s room were given the challenge of designing and building a boat. STEAM helps students ask questions, problem solve, think creatively, and produce innovative solutions. The children produced some wonderful designs and were soon ready for the buoyancy test.
The children in Miss Daly’s room loved bringing gummy worms to “life” with this simple chemical reaction. Using baking soda and vinegar.
In this experiment, gummy worms float and move as the vinegar (acetic acid) in the cup reacts with the baking soda (sodium bicarbonate) they’ve been soaked in. The chemical reaction forms carbon dioxide gas bubbles which float to the surface, pulling the worms with them and making them wriggle until the chemical reaction stops.
As a “Hands on – Minds on” school we love science experiments here at Togher N.S. Hands-on science experiments are fun for children of all ages. Most children are tactile learners and prefer to experience things in a hands-on way. Scientific concepts can be difficult for children to understand when just reading about them in a book. When a child explores a scientific concept with a hands-on experiment, they can see the concept right before their eyes. When doing an experiment, kids are much more likely to remember the science behind the concept.
The science behind the Magic Milk experiment: When milk is homogenized, fat particles are equally spread throughout the milk. When food colouring is added the surface tension of the milk keeps the food coloring in one place. When drops of liquid dish soap are added to milk with drops of food coloring on the surface, the soap will reduce the surface tension of the milk and react with the fat. This interaction will cause the particles in the milk to move around and create swirls of color. When the surface tension is completely broken the food colouring mixes together.
Senior classes joined Professor Baloney for a thrilling virtual science show with an emphasis on showing how much fun experimental science is. There was a mix of laughter and experiments with the professor!
We joined to discover if flour can burn? Can we make rocket fuel in the kitchen? And much much more…
We have been experimenting with chemical reactions as part of Science week. The chemical reaction between baking soda and vinegar is a wonderful “hands on – minds on” demonstration that children can enjoy and understand. Baking soda is an alkaline and vinegar is an acid. When baking soda and vinegar are mixed together they create carbon dioxide.
We really enjoyed predicting what would happen!
