On the afternoon of the Science Fair Room 13 and Room 21 investigated what would happen if we added different things to purple cabbage water.


We had 6 bottles marked A, B, C, D, E, and F, with 6 different liquids in them.


               Bottle A – Dishwasher powder

                  Bottle B – Ammonia

                  Bottle C – Baking Soda

                  Bottle D – Water

                  Bottle E – White Vinegar

                  Bottle F – Citric Acid


As you can see from the photograph we made a rainbow.
