In this Group 4 Project, the main common topic of the Group 4 Project this year is West Lake. Our theme was to look at the pollution of the lake, and use Biology, Chemistry, Physics and ESS to investigate the level of pollution.

In order to relate Physics to pollution in West Lake, we put up the question:

How does the pollution of water affect its refractive index?

In order to answer these questions, i have toured around West Lake in order to find ideal spots with different specification in order to determine the pollution level.

Area 1: Area one is a tourist attraction, therefore there is will be a moderate to high amount of pollution due to many visits by people. This puts its pollution level at moderate.

Area 2: This area is a field of lotus flowers. This is an enclosed area, and there are alot of growing lotus flowers therefore suggesting that it is a clean and less polluted. This puts it's pollution level at low.

Area 3: This area is also a field of lotus flowers. This is although not an enclosed area. This has more dead flowers, although the habitat is still hospitable, therefore putting it's pollution level at low to moderate.

Area 4: This area is the most common area for fishermen to work. Therefore we can conclude that there are alot of fish in this area, therefore the water must be clean. This puts it's pollution level at low.

Area 5: This is another enclosed area. This area is near a waste dumping area. There has been alot of history about garbage being dumped into this lake. This puts it's pollution level at high.

Area 6: This is the area at the opening of a sewer. This is where all the wastes from the sewer is dumped. Therefore we can conclude that the pollution level of this area is very high.

Area 7: This is the area inside the hotel Intercontinental. Before the hotel was built, the water was cleaned. The hotel also puts an effort in keeping the water clean as part of their environmental responsibility.
