Jetties: Help or Hurt? Do the Jetties at the beach actually help keep the sand on the beach, or do they allow it to be sucked out to sea? If the beach has a jetty, then it will lose more sand. I will supply a beach (sand, water, wave generator, and tub to hold it in) and the jetty (rocks). I do not think that I will need to use any supplies from you. None There will be no chemicals used in this project. 1. Create three identical beaches. Each beach will have the same amount of sand that reaches to the same point in the container. Also, each beach will have the same amount of water and a wave generator for each. The wave generator will be on the same power for each. There will be only one difference between the beaches, two will have a jetties and the other will not. 2. Over a course of two weeks, watch where the sand goes, or doesn’t go. Each night at the same time and place, take a picture to show the difference of the sand progression. 3. After two weeks, check the results and see if the jetty actually kept the sand in. My independent variable is the jetty.

 * What is your independent variable? **

My dependent variable is the erosion. My control is the beach without the jetty. My constants are the amount of sand and water, and the power of the wave generator. I believe each experiment should take about two weeks to fully let the sand situate. That would mean that it would take about a month to complete the project, since I should do the experiment three times to make sure the information is correct. I will work on it after school at my house where the beaches will be located.
