__**Pollution/Trash at Westlake**__ __**Question:**__ How has pollution/trash affect Westlake (The water & living organisms in and around it) __**Chemistry:**__
 * pH level of water - relating with buffering capacity
 * Turbidity of water - measure of degree to which the water loses its transparency presence of suspended particles
 * Chemical substances (like heavy metal) in the water
 * Lead II - precipitation between aqeous NaCl and water containing Lead II
 * Mercury - hard to carry out experiment
 * Cadmium - hard to carry out experiment
 * Chromium - hard to carry out experiment
 * Nitrate - using litmus strip

__Biology__
 * Comparing different parts of Westlake.
 * Will survey the fisherman at Westlake.
 * Compare areas where there is less fish to areas where there is more fish.
 * How many of these fishes are being caught
 * How long it takes to catch these fishes.

__**ESS:**__
 * To find out what type of fish lives in the lake
 * Base on the type and amount of fish judge how polluted the water is.
 * What type of fishes still exist and have dissappear through out time and why they have dissappear.
 * How does this change imapact the people lived around it.


 * __Physics:__**
 * Testing different locations to determine the pollution levels around the lake
 * use a multi meter to find the resistance and using the fact that purest water has the highest resistance, find which area of the lake has the purest water and which does not
 * will test eight different locations (5 samples from each location)
