Children in Fifth Class learned the importance of scientific investigation in solving crimes through this experiment.
Children looked at a sample crime story and investigated with forensic clues such as chromatography, finger prints and hair strands. They eliminated culprits based in this.
Cornflour & Water
Children in our ASD class did the cornflour & water experiment. The children mixed cornflour with water and it was solid when we hit it from the top but when we slid our fingers gently into the mixture it was in a liquid state again!
Skittles Experiment
Children in First Class were doing an experiment with skittles. The arranged the skittles in a rainbow pattern on a saucer and poured warm water over them. The shell of the skittle is made from sugar and it starts to dissolve in warm water.
Vinegar & Baking Soda
Senior Infants did 2 different experiments using Vinegar and baking soda.
One was to make a volcano in a cup. When we added baking soda to the vinegar, it began to fizz and come out of the cup.
In the other experiment, we placed some vinegar in a cup, and put some baking soda into the fingers of a rubber glove. We then turned the glove upside down. and taped it on to the cup. The rubber glove began to inflate like a magic hand!
Mixing Liquids
Third and Fourth Class mixed water, oil, glitter and food colouring. We saw how the oil didn't mix with the water and the food colouring only mixed the water and not the oil.
Playdough Experiment
Fourth Class made playdough by mixing cornflour, shaving foam and food colouring. It was very messy but great fun. They needed a lot of shaving foam and it took a while to mix to the correct consistency.
Absorbing colours
Senior infants observed kitchen paper absorbing coloured water and moving along it. They saw the colours mix and create a new colour.
Mixing Colours!
5th and 6th Class did a number of different experiments with food colouring.
Cornflour slime experiment- We created a thick slime using cornflour, food coloring and water. The slime is a non-Newtonian liquid which means it is different to ‘normal’ liquids. It gets thicker when it is pushed or pressed down.
Fizzy Colours- We created a fizzy liquid using vinegar, baking soda and food colouring. The bicarbonate of soda is an alkali, it reacts or changes when it mixes with an acid like vinegar because they are very different.
Paper towel colour mixing- We mixed food coloring and water in cups and used paper towels to watch the colours mix. Water moves up the paper towel because the paper is absorbent, it sucks up water. The colour travels with the water making the paper change from white to red or blue. Colours mix when they are joined together, red and blue make purple.
Rainbow Colour mixing- We used milk, food colouring and fairy liquid to create a rainbow effect. Milk is mainly water with another big ingredient: fat. The washing-up liquid bonds with the fat in the milk. The food colouring is pushed out because the bond is so strong.
Creeping colours and colour mixing
4th Class were looking at colour changing flowers and how the flower stem functions.
They also looked at fizzy colours, which involved mixing acid and base to create a chemical reaction.
Senior Infants were investigating creeping colours too!
Keep the water out!
Fourth class investigated how to make a piece of cloth waterproof. The discovered what happened when you drop water on the treated and untreated piece.
Puking Pumpkins!
Senior Infants investigated puking pumpkins! They didn't like the smell!
Chromatography
Fourth Class created beautiful Halloween art using chromatography
Investigating water!
Junior Infants have been learning about water, and have been investigating if it would change certain materials. It was exciting to see how some materials like coffee and sugar changed completely in water and others remained the same!
Which is the best coin cleaner?
Oil Rules!!
What dissolves in water?
First and Second class read about Hammy and how he tried to trick his friends by dissolving some things in water. Sometimes the trick worked and sometimes it didn't, because not everything dissolves in water!
