´╗┐Kevin Pontonnier Geography Internal Assessment Methodology: Before doing carrying out the experiment, please read ?safety and regulations? by ?Hong Kong government Health & safety? on www.hkgov.com.hk Wave Heights: To calculate the wave height, a metric ruler is needed. The student will have to go into the water, far enough to measure a wave, but close enough for safety reasons. The metric ruler will be placed where it will be touching the beach floor, and as the wave passes, he/she will measure the height of the crest and the height of the trough marking the two measurements on the ruler. The ideal method is to, when the wave passes, mark with your hands the top and bottom of the wave, then subtract the trough from the crest, which will give you the difference in height. ...read more.


Using the tape, measure the length of the stone; using the guide to determine the rock scale, deduce a suitable scale for the stone, also giving a description of its appearance (ie. Green; brown; brick red; etc.). Drop the stone, and move 2 meters down the tape, picking up a new stone. Repeat measurements (of length, scale and type). Move 2 meters down again and repeat. Continue until the sea is met. Repeat the entire process 10 meters to the left. Long shore drift: This process will be used to determine the direction of the current. Inflate a plastic balloon. Attach a string to it so it will not be lost somewhere and so that it will always be retrievable. Before measuring, determine the expected direction of the balloon (compass points + bearing). ...read more.
