Pour the water into the bottle with its top cut off. Then pour the water back and forth between the two cups about 10 times. Once filtering is complete have them bring the test tubes to you for observation. Once completed give each team 25 ml of the dirty water to begin to filter in their test tubes.

To start ask the child to make a hypothesis or prediction about the experiment. Begin by getting a jar full of dirty water. You will need a few supplies. Pour swamp water in the 2 liter bottle with a lid.
