Dependent Variable:
Velocity of wave (wave velocity)
Plastic storage container
Piece of wood
Height from which the wood is dropped and the way it is held before each time it is dropped Gravel-like substance that creates an uneven bottom—this includes both its physical material and the amount of it that is placed on the bottom of the tank during each treatment Time at which the stopwatch is started after the wooden block is dropped and a wave is created Problem:

It is a known fact about tsunamis that if the level of the water is higher, then the velocity of the wave will be greater. How does an uneven bottom affect the velocity of tsunami waves at different water levels? Hypothesis:

I believe that an uneven bottom will still result in the velocity of the wave being greater when the water level is higher. 5 MLA References with Annotations:

In addition, it helped me understand exactly what the original project would be testing, and also how I could make it my own. 2. “What are Tsunamis?” CBC News.

I believe that it is important to have as much information as possible about my topic, so that I am able to get the most out of my project and understand it to the fullest. 3. “Tsunamis.” National Geographic.

This includes a variety of submarinal conditions, and-although this is rare- those reasons related to meteors. 5. Cramer, Deborah. Ocean. Smithsonian. Smithsonian Institution. New York, New York: Collins Publishing, 2008. Print. (P. 62) •This printed source was very helpful, because it showed me a tsunami's effect on the whole ocean. This is an important thing to note, because it helps put into perspective how a tsunami is not only devastating once it hits shore, but also before it hits shore and is still a violent wave uncontrollably speeding across the ocean toward the shore, destroying almost everything in its path. Materials:

1.Plastic storage box (at least 40 cm long x 5 cm deep)

2.Source of water

3.Small gravel or pebbles (to be spread over bottom of storage box as representation of an uneven bottom in the ocean)

4.Piece of wood (2 in thick x 4 in wide x 8 in long)

5.Sharpie permanent marker

6.Metric ruler

7.Digital stopwatch

8.Bright ceiling light (above location of experiment)

9.Hand towel

10.Volunteer to run stopwatch

11.Lab notebook

12.Graph Paper

1. Find a well-lit location at which to execute experiment (favorably indoors and
free of commotion)

2. Remove any items away from location that could be damaged by potential
splashing water from storage box

3. Place storage box on white sheet and under bright ceiling light with no
surrounding lights in order to see waves as clearly as...
