Experiment 2: Depotition

Question: What happens to land when it gets eroded





Hypothesis: I think it will go separate ways and form a deep valley after it is dried out. I also think it carry a lot of sand with it.



Materials:4 cups of water, Bucket with small hole, Ruler, sand, hard sand, clay, Bucket with 3 pipes and small hole at end, wooden wedge.


Procedure:Put sand and hard sand and clay in the bucket with pipes. Mix the sand and clay.
make sand 20 cm in the length is the side without the hole. Take the wooden wedge and put it under the sand side. Put the ruler under

the bucket in the sand side. Pour water




Observation: When the water first touched the sand it did what it did in the last experiment, it just made a little pool and sat there after 1 minute it traveled to the slope part of the sand and the pathway towards the slope was slowly going down in the ground. after 15 - 30 minutes the water made it become a river and the water travelled through the streams to the bucket. After the water had ran out the river became a canyon which had crack in the side.






Conclusion: This one was almost the same as the first one. We did the same thing so I think that is why it was almost the same as the last one. What was different from this experiment was that the shape and the way of the canyon was different from the first was even tho it was the same experiment with no varibles changed. I wonder if there are a number of patterens for every single varible changed or is it just random every time.


The pictures were in the school laptop and I did not have them.
