Water - based experiment in jnr room
On 13th March, Pádraig from the Atlantiquarium visited our school. He and the children in the jnr room carried out an experiment using water.
Padraig got a plastic bag and a jug full of water. Then when we put our hand in to the bag and then into jug of warm water. Whe you take your hand out of the jug your hand is dry, but it feels as if it is wet. It a very strange feeling.
Tornado in a Bottle
Tornado in a Bottle
Materials
- 2 Empty 2L Plastic Bottle
- Strong Tap (Duct/Electrial)
- Water
- Food Colouring
Methods
- Fill one of the bottles three quater with water and food colouring (Make sure not to add too much, you onely need a light colour in water).
- Tape the empty bottle to the bottle with water (upside down-opening to opening)
- Turn the bottles upside down and swirl in a circular motion.
What happens
When the bottles are turned upside down the air in the bottom bottle wants to get inot the top bottle as fast as it can, while the water wants to get down as fast as it can. When you swirl the bottles it forces the water out to the edges and fastest route is for the water go down the outside while the air comes up through the middle. This forms a tornado cone in the top bottle.
Volcano
Materials
* Vinegar
* Bread soda
* A large spoon
* Glass container
Methods
1. Add about half a glass of vinegar to a glass container
2. Just mix a few droips opf food colouring
3. Add a large spoon of bread soda
The volcano should erupt nicely. If you wish the volcano to erupt over the container just add more vinegar and bread soda, care should always be taken with food colouring as it does stain clothes.
What happens
Bread soda is a base substance and vinegar is an acidic substance. WHen the two substances are mixed they react. This reaction causes a foam and emits Carbon dioxide.

Ocean Currents
Ocean Currents
Materials
- 2 Jam Jars (Same Size)
- Squares of card/plastic
- Table salt
- Food Colouring
- Paper Towels
- Plastic/Baking Tray
Methods
- Fill one jar with colourless fresh water (from the tap is fine) and the other jars with coloured salty water (tap water with salt added can be used). Place both the jars in the tray.
- Place a piece of card on top of the salty water and invert the card (turn it upside down), the upward pressure of air will hold the card in place (most of the time).
- Place the saltwater jar on top of the freshwater jar and have someone remove the card. Do this over the tray in case of spillages. Observe results.
- Repeat No 1 - this time put the freshwater on top of the salt water, remove card and observe the results.
- Repeat No 1 - this time put the fresh water on top of the salt water and turn the jars horizontally (sideways). Remove the card and observe.
What Happens
When the saltwater was placed on top, the water in the two jars mixed togheter. This is because saltwater is heavier that freshwater and sunk down through the freshwater in the bottom jar. When the freshwater is place on top is floats on top of the saltwater at the bottom.
Hydothermal Vents
Hydrothermal Vents
Materials
- Large Jar with wide opening
- Small Jar
- Food Colouring
- Cold Water
- Hot Water
- Baking Tray
Methods
- Place Large Jar in Baking Tray in fill 80% with colour water
- Fill Small Jar with Hot Water and colour with food colouring
- Slowly place the Small Jar in the Large Jar
What Happens
The hot water in the small jar comes out into the big jar to the surface because hot water is lighter the cold. Hydrothermal vents are areas in the ocean where heat esacapes from the earth's mantle through cracks in the earths crust. This heat warms up the surrounding water and causes it to rise as is observed in this experiment.

SAINT CAILLIN'S WELL
Saint Caillins Well
This holy place where people come every year on November the 13th to pray in honour of Saint Caillin, our local patron saint of fishermen. In olden days, celebrations went on for three days at a time, with house dances going on all night unil morning.
Nowadays people from the parish and all the surrounding parishes start visiting the well from midnight to do the Stations, many in their bare feet.
The ritual is as follows: pilgrims kneel down at a mound by the well and say a few prayers; then each pilgrims picks up seven stones and says an Our Father, Hail Mary and Glory Be To The Father as they walk around the well, also throwing a stone on the mound each time they walk around. This walking round and praying the ususal prayers are an ancient tradition, but in fact prayers will serve just as well.
It is said that fishermen carry water from the well and no boat has ever sunk. Many cures have been reported from sick people who visited the well.
