       Counclusion 



throughout the standard experiment we relized that when the water went into the land it did not create a river from the begining instead it created a river from the end. the river was cshaped as a fan. the sand went into the water and went to the bucket of water. the clay and fine sand more of it had went into the water than the rough sand because they are lighter and softer thatn the rough sand.
