[Blanca's Blog] what i Think

I think the result changed from the experimented to group to group because we had humus,and sand,clay,and gravel.In investigate two we had humus and clay and sand,and some bubbles at the top of the cylinder others had some gravel,in them thats why some groups thought it had more erosion. Some people thought that the other group had more erosion because they saw gravel.
