my group was assigned to go to the Labrador Park.
It was fun but tiring...
The beach was "nicely" littered but nevertheless, we had conducted experiments on the organisms which are living on the beach. Sea snails can be found near the shores and there are even some spiders located on some rocks, too bad i did not bring my camera, i forgot =(
but nvm
i learnt how to use a data-logger and took specimens of soil and sand and especially the water. i think the pH of the sea water was around 5.--, if i recalled properly.
One of the teachers there taught me how to take the pH of the soil on the walls of rocks which were quite far from the shore, i added the soil which is brown in coloured and Eric's West Spring water xD, and the outcome of it is...
Good news: Homemade "Milo"(because of the brownish and opaque colour of the water)
Bad news: i spill some on my uniform...
but i didn't mind
the temperature of the sand at the beach was around 33°
wow it was very warm, so much so that Joel sweat...
after recording the data, we took a look at some of the snails scattered around the area.
but before that, i spotted something dangling from Joel's behind, it was a spider
then i laughed(not like Nicholas) as it was funny, how did the spider climb on Joel without him noticing?
after that i go take a look at some snails.
they had tough and cold shells, some are quite tough but a few are extremely tough, so tough i could step on it and it will not break.(sad, got owned by snail)

then, i checked on their soft bodies, Joel asked me to pull them up and i could not. (I'm so lousy, i couldn't T^T)

Data:

TEMPERATURE-32.1°C
R.H-39.5%
P.H-8.2(somewhere there)

My hypothesis:
Sea snails are rarely located far away from shores as their bodies must be moist and they could not withstand 33° without water. Some of their shells are patterned so they could easily camouflage or blend with their surroundings which makes them hard to find and thus harder to be preyed by their predators. Some of their shells are also spiny to get extra protection and makes their whole body harder to swallow. Their muscular foot act like suction cups so these little and light snails would not get eaten up if they do not have spiny shells are washed away by strong waves or get dislodged by rocks near the sea.
In conclusion, Labrador park is not a place for us to litter if we want to find weird spiders that creep behind people's behinds or spiny shelled snails living in the water or rocks that are funny looking that they create tide pools. Labrador park is a nice place to skip rocks too.=)
