Yesterday room 13 did a science experiment called the red cabbage indicator. We used red cabbage juice to test whether something was acid or alkaline. We put the cabbage juice in a test tube first then another ingredient to see what colour it changes into. First we added Coca-cola it slightly fizzed and changed to red, the next thing we did was egg white it changed to a blue colour, then we added tomato juice and it changed into a purple. After that we mixed baking powder which fizzed up then changed to purple. Next was lemon juice and it turned red. We also did orange juice which changed to a red purple colour. Lastly we tested milk, this changed into a light purple. I really enjoyed doing this experiment and I can't wait until the next one.
