SLOPE CHANGE

BY ELIZABETH RAMEY AND AVA WILSON

OUR HYPOTHESIS ARE:

AVA'S: I think that by lifting the slope it will change how much water will go down  at one time.

liz's: I think that it will change how much water will go down at one time.

Question

how dose the slope of the tilt of the land affect how much water changes the land?

our materiais

~stremtable   ~tilt  ~bowl  ~water  ~sand ~ clay  ~humas  ~soil   ~rule  ~cup with holes

before water!!!!!!!!!!!!!

our variable

the tilt of the land.

Looking how much the soil moves

after the water !!!!!!!!!!!!!

steps

1:get stream tables

2: get 2 tilts

3: get cup

4: put bowl  under the stream table

5: use ruler to meaeier how much the water moved the sand

6:pure water

7: watch it flow

measurntis

for two lifts :23 in

for four lifts :30 in

conclusion

for our experinent we tried to see how much  sand would move by the lifts.

this is what hapend `when we  awnser qustion. it changed the way the water came down.  On the 4 lift the water came down really rough so the sand came down with it.  On the 2 lift the water came down slowly and it didn't come down as hard so the sand moved a little but not as much as we thought it would.  It moved more sand on the 4 lift one because it was so high that it wouldn't stay in place when the water came down.
