Science Project 2005
PurposeThe purpose of this experiment was to see how different soils affect the growth of a pinto bean.
I became interested in this idea when Don Jordan, my grandfather, was describing different types of soils and how they affect the growth of a plant.
The information gained from this experiment will help produce more trees and plants faster, so they can clean the polluted air around the plant's area. Also knowing this information will help farmers produce more vegetable
HypothesisMy hypothesis is that the cotton would increase the growth of a pinto bean the most.
I base my hypothesis on Don Jordan, my grandfather, who did this experiment before me and discovered that cotton was the best material to grow pinto beans.
Experimental DesignThe constants in this study were:
To measure my responding variable I will use a metric ruler. Growth will be checked weekly.
ResultsThe original purpose of this experiment was to see how different materials affect the growth of a pinto bean.
The results of this experiment were that a pinto bean grows best in cotton.

ConclusionsMy hypothesis was that the cotton would be the best material for the pinto bean to grow in.
The results indicate that this hypothesis should be accepted. The pinto bean grew best in the cotton.
If I were to do this experiment again I would start with many more cups of each type, so that more would grow. I would also use some soils that were not as powdery as the Moxee or the Blended soils. They compacted too much and kept the plants from growing. I would also repeat my experiment another time or two from the very beginning to make sure my results were reliable.
Because of my results I wonder how wheat or corn would compare to beans if grown in different soils.
