1. They can provide students with experiences that cannot be duplicated in the school but are nonetheless an integral part of the general knowledge which are worthwhile for the students.
2. They can enable teachers to expand students' learning beyond the walls of classroom into the vast community outside.
THE AIM OF THIS PARTICULAR FIELD TRIP :
1. To understand and learn the various types of basic field work techniques after the self-experience during the field trip.
2. To investigate and study the ecological environment of the rocky shore habitat.
3. To find out the major organisms present and their adaptations to the environment.
4. To find out the effect of the main physical factors on the distribution of organisms and the interrelationships existing among organisms.

BRIEF INTRODUCTION OF ROCKY SHORE HABITAT
Rocky Shores are the regions with strong waves all the time which erode the rocks surface and thus leave the rocks exposed. Due to the different period of submergence along the rocky shore as a result of tidal effect, it is usually divided into three main regions : a. Splash zone -- a region rarely covered by the sea, but is usually sprayed with salt spray at high tide. Sometimes, it may be drenched in a heavy gale. Aquatic plants and animals are rare in this zone. b. Intertidal zone -- Also known as the littoral zone. It lies between the mean high water spring tide mark and the mean low water spring tide mark.. All the plants and animals in this zone must
