EXPERIMENT ONE: WATER EROSION
QUESTION: What happens to land when water flows over it?
HYPOTHESIS: I think when water flows over a land, the surface of the land gets covered by water and becomes wet. And the sand gets softer.
MATERIALS:
- 2 buckets
- 1 ruler
- wood piece
- ruffle sand
- clay
- fine sand
- water
- stream table
PROCEDURE:
First we putted the fine sand, the ruffle sand and the clay and mixed them all together.
Second we measured the sand and put the ruler on top of the bowl and put the small bucket with the small hole on the bottom on top of the ruler. With the wood piece we putted under the stream table, and then we putted a bigger bucket for the bottom because it could hold the water that came out of the stream table.
After that we pourd into the small bucket 4 cups of water.
The water went into the sand really slowly and it formed a little canyon.
When we were done with the experiment we took all our materials back to our classroom.

OBSERVATION:
I saw that the water covered all the sand and that under the bucket the water created a big deep hole. A lot of water went out of the stream table's hole.

CONCLUSION:
My prediction was correct because I guessed that it cover the sand and it actually gets softer.

Very nicely organized! About your conclusion, what can you say now about the effects of water running over land? How can you connect it to the real world?
