experiment four: aquatic erosion.

Question:    what happens we two streams come together with big and small cup.  

  hypothesis:     that the water will connect and after a while  there will be one big river   


 materials:  water, two cup with hole, tray, sand, rule, computer, wooden wag, clay, bucket. 

 procedure:  we put sand and clay  28cm in the tray and then put it on the wooden wag then put the water in the cups with a hole and poured water in it and put the bucket near the tray on the ground. 


observation:       we saw that the cup with the bigger hole was so quick and the other one was so  slow. The big one formed a valley but the other one formed a valley for a long time and it was steep and it finished  later  than the first one
