Brooklyn Omaru Creek testing for- colour
Testing Omaru Creek for - I am going to find out: What colour the water is. I am going to test this by:comparing different water samples from the culvet, the bridge, the tap and the sea Resources and equipment: 4 water samples from the sea, the bridge,the tap and the culvet I predict that:tap water will be clean,culvet water will be dark,sea water will be dappled and the bridge water will be dirty. I think this because: Results of my tests Sea Water was cloudy Tap water was clear and clean Omaru Creek water by culvert had bits of rubber off the road floating inside the water. Omaru Creek water by bridge was light green My conclusion (what I found out): That the creek had bits of rubber from the road in it. Why I think this is: The sea water is clear because of the salt thats keeping it nice and clean.
