 Question:


what happens when the force of water is increased
     



         Hypothesis:

       i think the cnayou will go deepper



            Meterials:  fine sand, rough sand, a ruler,  plastic cup with a small hole, clay bucket, wooden wedge and a stream table.





         Prrocedure  :  

1.  we set up the computer 
2. we put the clay, fine sand and rough sand into the big tray 
3. we mixed the caly, rough sand and fine sand
4. we put the wooden wedge unnder the strem table 
5. we placed the stream table at the edge of the table 
6. we placed the bucket under the table 
7. we placed the ruler then on it the the plastic cup with a hole at the bottom 
8.  then we poured some of the water into the plastic cup with a hole 
9. then the river started accuring

        Observation 

10 seconds- the water is starting to flow without creating a canyon
20 seconds- making very small canyons at the bottom of the sand
30 seconds- the canyous are becoming a bit larger
40 seconds- we realized that with the previous experiments the canyoun would start from the begining to the end but this experiment is it creating a canyon from hte bottom to the top
50 seconds- water is flowing very fast
60 seconds- the canyons are becoming a bit thicker
1 min- the sand is becoming weaker.
1 min and 30 seconds- the canyouns are becoming thicker not longer
2 min- the water is making smaller canyons



       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.
