Pupils from Primary 7 took part in an event held at the Odyssey arena where the world record for largest Science lesson was smashed. There were 1,339 school children from all over Northern Ireland involved and it proved to be a very enjoyable day. Here are a few recounts from Primary 7 pupils.
Recount Writing
Although I already knew that salt dissolves in water, I thought it was very clever how Scientific Sue told us to mix water with salt and pepper, so we could actually see the salt dissolve. It was fun and educational at the same time.
I have learnt some new facts from our trip to the Odyssey Arena, Belfast. I learnt that Chromatography is a method of separation that scientists use to separate colours and dyes. They use special paper to dip the colour or dye into the water so that the colours used to make the original colour separate upwards on the sheet of paper. This is how we now what colours to mix if we are making colours.
I also learnt that by draining the pepper from the salt water with an empty teabag, the water had no pepper in it and the teabag had lots of pepper in it. Eva also liked how the pepper-filled teabags tasted.
Another fact I learnt is when you use Chromatography on an orange marker, the colours that spread out are red and yellow.
However, the most interesting fact I learnt was that, if we use Chromatography on an ink cartridge, we can tell whether the ink was used to make forged money, or if it was regular ink that we use everyday. We did this to help the police with an investigation on the forged twenty pound notes they have been finding lately. This is called Forensic Chromatography.

My Recount on our trip to Odyssey Arena
Although I already knew that mixing two colours gives you another colour, red, yellow and blue are primary colours and science can solve a lot of things even for the police.
I have learnt some new facts from our trip to Odyssey Arena
I learnt that:
*When you put salt in water it dissolves
*When ink is put in water it fades to different colours
*By putting ink on card and dipping it into water, the ink will fade and stretch up the card.
I also learnt that Chromatography is a technique used to separate things such as different coloured dyes and salts and peppers.
Another fact I learnt was if you put salt and pepper into water, the salt dissolves, and you can get the pepper out by putting it in an empty teabag.
However the most interesting thing I learnt was that there are currently fake £20 notes being used and since we researched on ink it could help the police to find who made the notes.

Guinness World Record
Although I already knew that salt dissolved in water .
I have learnt some new facts from our trip to the largest practical science lesson. I have learnt about separation and how it works , here’s more detail on what I was taught.
I also learnt that using water and felt tip pens you can discover what colours are in the pen, you use a special type of paper called chromatography paper.
Another fact I learnt was that money uses a special type of ink that helps forensic scientists solve counterfeit money problems .
However the most interesting fact I learnt was that using an empty teabag you can separatesaltwater from pepper!

Our Trip To The Odyssey
Although I already knew that salt dissolved into water
I have learnt some new facts from our trip to the Odyssey to help me understand more about science
I learnt that which colours mixed together made other colours and that food colours and flavours dissolve into water.
I also learnt that things can dissolve into gaps and spaces also if you put a dot of pen on a piece of paper and dip it into some water the ink would space out because the water travels up the paper and the water takes the ink with it so it would change colour.
Another fact I learnt is that counterfeit money ink can look real and also have water marks and that you can also use empty tea bags to separate things like salt water and pepper.
However the most interesting thing I learnt was different coloured dyes may be separate by a technique called chromatography.
