| Hypothesis:
I think that water will work better than oil and vegetable oil when lubricating
the fault.
|
|
| I am trying to find out if water or vegetable oil lubricates the fault better. | |

1. Place two
pieces of plywood next to each other
2.
Pour liquid into crack where the two boards meet.
3.
Use masking tape to stick the two boards together
4.
Cover moist sand over the surface of the boards until it is one inch thick,
and there is some space around the edges.
5.
Remember where the crack was in the sand, and put the toothpicks over it
6.
Gently shift the two boards in separate directions to create a miniature
earthquake
Note:
Make a different model for each liquid

Water- The toothpicks seemed to all be on one side of the fault. They moved in all directions, and often fell on top of each other. The toothpicks didn't fall in any specific pattern, and just flew all over the place. The fault line moved slightly to the left after I shifted the boards. Vegetable Oil- Like the water, the toothpicks were all on one side of the fault. A majority of them were pointing towards the lower right-hand corner. The toothpicks didn't fall in such a chaotic manner. Again, the fault line moved slightly to the left. From my stand point, I would say that the vegetable oil worked better than the water. |

| From my project, I learned that my hypothesis was wrong. It turned out that the vegetable oil lubricated the fault better than the water did. | |
