My group was assigned to Labrador park.

It is very hot and sunny there,and my group members sweat a lot.
Over there, we were asked to collect data of the place.
I learnt how to use the data-logger and took specimens of the sand and seawater.
I spot some spiders and there is also small shell crabs.
After,we are done collecting the data,we go and play with the rocks some of my friend even threw rocks at the sea.

Abiotic Data(Physical Factor)
Date of Observations: 2/September/2009
Time of Observations: 2.30pm to 3pm
Weather conditions:Very hot and humid
Soil texture: Rough,soggy
Soil temperature:32.1ºC at 10 cm beneath the surface
Soil pH:8.2

Data(Results):
Temperature:32.1ºC
R.H:39.5%
P.H:8.2

My hypothesis: How does the snails adapt to the environment?
My conclusions:
They have a very hard shell to protect themselves from their predators.Some of the shells are also patterned,this means that they can blend with their surrounding and thus harder to get found and eaten by their predators.They also have a very strong foot to help them hold onto rocks and will not get wash away when it is high tide.
