So  in Science we are doing some labs with stream tables, soil, and water.  My groups real world problem is erosion and how much soil is eroded with so much water.  The amounts of water are 1 water bottle 1 1/2  water bottles 2 water bottles 2 1/2 water bottles and 3 water bottles. My hypothesis stated that the more water the more soil that would get eroded.  My hypothesis was correct! My highest data point was over 610 grams and my lowest was 75.4 grams.  Some problems we had was the scale couldn't weigh the soil because the soil was too heavy also we were not able to get all the soilthat was eroded.  Questions I had if I were to do this again is: What would happen if we packed the soil down? Also What would happen if we got new soil each time instead of using the same soil?  What I learned was what meandering streams are ( curving streams).  I also saw how much soil was eroded with water. I think this lab is really cool and interesting.
