In room 15 we have been learning about the PH scale and we did an experiment testing different liquid based objects such as baby oil, jelly and other things we used tea as the indicator and used an eye dropper to pour the tea into the thing we were testing.
We did the experiment in our class with room 19 we learnt that coke is very bad for you but diet coke is actually worse than normal coke because they take out the sugar and put in another acid.
Some of the things we tested were quite astonishing such as mayonnaise which is actually quite acidic and Sunsilk shampoo which is extremely acidic and jelly which is really acidic because of all the sugar that gets put into it but not everything is really acidic Listerene mouthwash is quite alkaline and toothpaste which is neutral.
There is one thing that is quite astonishing bottled water it is really acidic but normal tap water is neutral which is quite strange.
