The outcome of my experiment was the same as my hypothesis as the turbidity of the dirty water changed most drastically than the other liquid when it was filtered. In the dirty water I added a small bowl of garden dirt to 1 cup of water and 1/4 teaspoon of vegetable oil. The turbidity of a liquid is the cloudiness or haziness of a fluid caused by large numbers of particles that are generally invisible to the naked eye. The other liquids I tested including black tea, soapy water and Coca-Cola did not contain as large particles as the dirty water (as the soil does not dissolve in water) therefore when these liquids where filtered they did not change their turbidity’s as drastically as the dirty water did. This is the reason why the turbidity of the dirty water (671.2NTU) changed more drastically than the Coca-Cola (56.5NTU), black tea (84NTU) and the soapy water (131.1NTU)
Below I have attached a video, to help explain how I have conducted my experiment, hopefully making it easier to understand:
