Overview

Objectives/Goals To Find Out if a metior hit water at what angle would cause the biggist wave. Methods/Materials The materials in the experiment used were a 3" by 3' tube, 1 lacrosse ball, 1 plastic container, sand, camera tripod, clamp, protractor and water. The methods in this experiment were: 1: Setting the tube to a certain hieght and angle. 2: My dad drops the lacrosse ball and takes the time while I mark the wave length on the sand. 3: We record the data Results The results showed that the 90 degree was the shortest wave length. The 45 degree angle created the longest wave. Conclusions/Discussion The reason the 90 degree angle was the shortest was because the water compressed under the ball then released losing a lot of speed. The 45 degree angle hit the water pushing the water forward causing a bigger wave.

Summary statement

I used a lacrosse ball dropped from a specific angle hitting water to represent a meteor hitting water making a large wave/tsunami.

Help received

Dad & Brother assisted with ball drop & timing. My Dad also assisted me with MS Excel spreadsheet.
