JACKIE ^^

The fieldtrip to the Labrador Nature Reserve was a fun-learning experience.
From the Aerial Tower to the Jetty to the Promenade and lastly the Dragon Teeth Gate.
We were exposed to facts we learnt in class,topics like Natural Vegetation,Weathering and Coastal Studies.

Walking down the stairs of the Aerial Tower,we get to experience the Tropical Rainforest in an equatorial climate.
Features like the five distinct layers-
the emergent,canopy,understorey,shrub,ground layers and trees which are 40-50m tall.
Leaves which are thick and leathery,smooth and waxy with downward pointing drip tips.
Smooth,thin barks and also shallow roots and buttress roots.
Unfortuantely,the forest is a secondary forest.

At the jetty,we get to experience the low tide.
We were taught how to calculate the wave period with a stopwatch and to observe the swash with white foams.
Features like the notch,wave-cut platorm,cliff.
Having a better understanding for the swash,backwash and the difference between constructive and destructive waves.
As we proceed further down to the Promenade,we also learnt about the protecting of the coast. Seawalls were built to reduce the effect of the strong waves which in turn help to prevent further erosion.

Last but not least,at the Dragon Gate teeth,we were told that the type of rock found there was granite and it would be broken down into smaller pieces due to oxidation.
We were made to observe the lines of weakness found on the rock,which would thus hasten the rate of weathering of the rock.
Also,we experienced the sea breeze which kept us comfortable despite the hot weather.

In conclusion,i feel that the trip to the Labrador Nature Reserve is worthwhile beacuse i know i have learnt quite abit.
Looking forward to further fieldtrips planned.
