When you do this experiment you need a
tin pan, some sand, and some water. First you take the sand
and make a slope in the pan. After that you try to predict
what will happen when you pour the water onto the slope.
Then after that you pour the water and see what forms. You
will problobly notice the little groves the water carves out
of the sand. You will probably call the grooves rivers and
streams. You will notice that there is a big puddle of water
(in other words, a little ocean) at the bottom of the slope
you made with the sand. Then you draw a picture of what it
looks like after the water settles down.
