the first thing we did was make an indicator which is water mixed with purple cabbage, we then experimented a little bit with vinegar and baking soda and worked out that vinegar makes bases and baking soda made bases. but for some reason we couldn't make a neutral.
Acids are Reds, Oranges, and dark Yellows, Neutrals are Yellows, Greens, And Baby Blues, and Bases are Purples, Pinks, Blues and Dark Greens. We made Black, Dark Blue, Green, Light Blue, Red, Pink, and a double layered Purple and Turquoise.

Algae In The Tukituki River
what is causing the Algae to grow
The Tukituki River is different to others around the country because phosphorus is the main cause of the slime and algae seen in the river. research has shown that if the amount of phosphorus in the river is reduced, it will it will stop the slime and algae from growing. This will give us a more attractive river for swimming, fishing and other recreational activities, not to mention it will make it healthier for us to drink. Other things causing the slime and algae include the amount of light reaching the streambed and the amount of frequent floods in the river.
what can we do to stop polluting the rivers
some things we can do to reduce the Phosphorus and make our water healthy again include,keeping stock out of the water. New stock exclusion rules will reduce the amount of sediment, bacteria and pathogens entering the water. beef and dairy farming must take a fair share of the blame.
