Wash Out

Overview

Objectives/Goals My goals are to determen how slow low energy waves verses the high energy waves could affect the beach. Methods/Materials Methods:Step1: cover the shallow end of the paint roller pan with 1 quart of sand, making a beach. Step2: pour 2 quarts of tap water in the deep end of the pan. Step3: note the way the beach looks after you pour in the water. Step4: make waves by laying a pencil gently on top of the water, then slowly move the pencil up and down 1 inch (2.5 cm) into the water each time. Note: Repeat 3 times each using different things in water. Example: Toy cars on beach, twigs in water, and rocks in water. Step 5: Then observe the "beach" after the water waves hit against it. Materials: Pencil, Paint-roller pan, 2 quart (2 liters) of tap water, 1 quart (1 liter) of sand, little toy cars, twigs or little pieces of wood, rocks (small). Results With Sand: After two minutes of making study waves the sand began to erode after another one an a half min. more sand began to go with the waves. With the twigs: The sand bareley moved. Whith the cars: the sand didn't moved but started sinking. With rocks: little amount of sand was washed away. Conclusions/Discussion For our conclusion we concluded that high energy waves made more damage to the beach then low energy waves.
